I have an old Philly 148 GTL. I have had it in all my convertible Jeeps. Since I do get caught without my soft top in the rain from time to time, I would have to say the Philly 148GTL is extremely durable. I easily make contacts over several states on sideband. It is looking a bit worn over the decades, but it still runs like new!
Probably the most Iconic 11m band SSB Transceiver.. From the early 80s.. My personal favourite is the Teaberry Stalker 9 FDX... Ticked all the boxes, particularly in the UK with the UK 27/81 FM included.. On SSB outstanding RX TX...
Thank you so much for this and ALL your video's. This one was particularly helpful as you went to the trouble to show us exactly what to turn. I don't have the gear to measure and do it all but it's nice to know what and where they are. Thank you again!!
I have Uniden Grant XL radio built Phillipines also built in 2004 radio also open Clairifer and tune up nicely to ! It also well built for plus filters are like HR 2510 10 meter rig and I have adapter 5 pin to 4 pin Cobra with stock mics only needed! Love it 100%
i LICK my 148 daily. it is such a great great radio. i miss the radio so much, and sometimes i wonder if the CB craze will ever come back again. started 93, and i was such a fan up to 2001, or so, i spent most of my day behind the MIKE. lots of groups all around the channels, so many kids, it was fun fun fun. i loved it. lots of dx ' ing. locals, etc, you name it, mobile operation. oh well. :) thanks for the nice video.
Basically a Cobra 2000 in a small package. Provide a beefy trouble free power supply and now yer in business! One of the smoothest sounding receives you'll ever hear due to the dual conversion. Great on sideband. Highly recommended for folks that may not know. Hard to beat. Avoid the Chinese stuff.
I bought my 148 GTL back in 92’ when I started driving 18 wheeler and I still use to this day . A bit different then the one you have. Mine has on/ off and SQ. In first position.
good job. I have the same radio I have sent to a guy I know in my town how to fix radios and he had it over 12 months to turn it up I was on his back about it's to fix it. I told him I'm going to pick it up today he told my wife on the home base radio if he comes over he's will use his baseball bat on me LOL air came out with a baseball bat and I did see a pole next to his door and I picked it up and he slammed the door in my face and I bashed his door with the pole the police officer told me to go home he pack the box away and gave it to a some person I know. he thinks he knows how to fix CB radios I think you fuck my radio up it just needs a tune-up now it doesn't have any modulation my needle moves a little tiny bit I can't hear myself on my other CB radio. in Australia not many CB shops fix these 27mhz no more only UHF CB radios a guy in Queensland he does fix the radios in his own home but he's got all the machines that's good. looks like I got to send the radio to his home to fix it. 😎
I'm looking for help trying to troubleshoot mine. It was working... but now my channel display is blanked (not visible). Does it do this when the PA switch is on? I thought that might be a clue to what's wrong, if it is? I was trying to fix a detached black wire inside of my microphone, and when I turned it back on, the display was off. Is it possible I shorted something out? Help if you have suggestions.
hello I'm a newbie and a friend gave me a tiwan made 148 gtl the radio is five pin but the Mike is four pin and the colours are red,black,purple and braid how do I wire to the radio I'm going crazy here thanks
I own a 148 gtl. While keying the mic in usb or lsb the needle doesn’t rotate to the right in the meter while transmitting. The needle is supposed to rotate to the right the same as keying the mic in am right? If anything the needle in the meter pegs itself all the way to the left.
O.K. wow ! The Cobra 148 GTL according to my impression is that it is a great AM / SSB mobile CB radio. That being said, I went out sort of looking for one. Most recently, over in Canada just a stones throw from Buffalo New York and the American (U.S.) border I am pretty sure i saw a Cobra 148 GTL in a showcase or shelf behind a glass sliding door at a place called the Pilot Flying J - looks like a truck stop, to me - so, I wanted to snap it up - impulsive buy it - and I walked up to ht eocunter and it is said to me that the person who is in charge of the radios is not prresent. i should up a few days later and the radio is not there. WHAT A LET DOWN. I am on a mission to get my hands on a Cobra 148 GTL CB radio. Please help.😀👍
Do you offer a 148GTL / Grant XL video showing the TR24 RΩ mod or the NPC mod? - Also, I came here searching for the Imax 2000 exposed video but none seems to exist.
i have the same one as yours. works well, power output is low and the 5 pin is really gay but other then that its a nice radio. shitty segments in the channel selector and the needle for the meter bangs against the right side when on sideband
I have 2002 Undien Grant XL like Cobra 148 GTL video but got in Undien heavy duty finals in also use 5pin to 4 pin adapter connector for common 4 pin mics Undien and Cobra stock ones and Undien Grant XL got in 2010 Januray 6. from my neice Nicole found in Pawn Shop for $70.00 dollars! It had power cord, 5 to 4 pin adapter with Astatic 636 L low impencedence stock mic , 4 bracket knobs and Am need repair by resistor also Choke and antenna jack plus got orgnial bracket from CB / Radio store sells them and Double Tune Up! Use the radio in my vechile with homemade mic from parts it a Citizen Case , key switch 1970 type & Turner 1960 mic element and 10 foot cord with 4 pin Cobra plug sounds like Power Mic but have Mic Gain at 1:00 spot for Am or SSB modes use Wilson 1000 with 68 inch whip ! Plus K40 both flat match too !
I still have my old 148 GTL from 1979 with original box. The older ones are great and work awesome on SSB. The new Chinese made 148 GTLs are completely useless on SSB and Cobra has NO PLANS to improve the audio problems with the new ones on SSB. Cobras stance on thier radios these days is "take it or leave it"...........................
I got 148gtl-dx Export radio nice radio but the fm on my is disable as well cw too only am model work but it do my ANTENNAS for turn 28 to 29 meter band other that nice cbradio
Don't know bout that..i have one and yeh out of the box it wasn't good at all. Little work and tuning and this thing does EVERYTHING the old one did! Modulation on sideband was easy fix, peaked , tuned with all the channels, and clarifier unlocked (-11 +6.5)
If you are trying to setup a base station but live in an apartment (second floor) with no balcony or anything....anyone have any good recommendations for setting up an antenna to get out a good distance on SSB?
r131 makes a huge difference in modulation, I've owned a couple 148s and when you clip r131 your audio will go to like 120% and its super loud, and from far away you'll be heard, 148 is a good radio and its basically a cobra 2000, which is a super bodacious radio, 148s are loud and sound good with the limiter cut and a d104.
+alizarin alexander I disagree. They sound like crap with the limiter cut. If you look at the audio wave, it becomes narrow, and rectangular shaped. Modulation gets to be around 200% or even more. You also get all sorts of weird harmonic radiations all over the spectrum when you do that. The channel width get super wide and it bleeds up or down 3 to 5 channels. Clipping parts out of these is the worst thing you could ever do. Also, if you clip the limiter out, is not a single bit louder, than just cranking VR-11 all the way up. The final simply cannot reproduce that much extra audio power, so it stalls out when the audio limits reaches the physical limits of the finals. (Think stalling an airplane when it tries to climb straight up) So not only do you get a super distorted wave form on the scope, but a good chunk of the audio is simply never added to the carrier at all. Just crank up VR-10 and VR-11 the way the factory intended it to, and you will have the loudest, cleanest radio ever made. Even today, the ONLY radios that can compete with it are build on the modern version of the same original main board. The Galaxy today, for example, uses the same identical audio chip as the original 148 did. It's never been upgraded.....nothing beats it, so it stayed the same all these decades.
VanishingNomad all my radios get the limiters cut, its easy to dial back the modulation and its plenty clear, it only gets the distorted sound when its turned up very high and sometimes it sounds really good like that, but to each is own.
VanishingNomad the problem is that most stock radios the modulation is very low, sometimes as low as 50 or 60% and thats a mud duck dude, doesn't matter if you have a power mic, i've hooked up base D104's to stock radios and the modulation is still 60 or 70%, a power mic doesn't affect the modulation % at all really, it might make you sound loud at short ranges but at long ranges it does nothing, i've tested many times many years ago, all my friends had bases and mobile cb's i would have people get on my base station while i was is my car the next town over and do countless tests using different radios mics etc, i have meters that measure modulation and power etc, so i know what a mud duck is, i would run a galaxy 2100 or cobra 148 in my car using d104 mics, steel whips, and messenger amps, usually 500 watts min, i could go park on a hill in the los angeles area and people 30 to 40 miles away thought i was in their neighborhood, i've used all sorts of antennas, i had a beam on my roof, my friends had different setups, i guarantee you, if you and me had the EXACT same radio and antenna and you left the audio 60% and i cranked mine up to 120%, i would step all over you and even if you had a 300 watt amp my audio would cut thru your carrier, thats a fact, i know for a fact lol i've done it, you're talking to someone who had a CB when i was 10 years old, putting my own antennas up on the house i saved up from delivering the paper and doing odd jobs, i had cbs all my life, even now i have a base, now if you can raise the audio to 100% or very close to it without cutting the limiter great, but thats not always easy to accomplish if at all, so if i'm gonna have a choice of a radio with 60 % audio or 100 plus % audio, its a no brainer.
+alizarin alexander , I don't leave the audio at 60%. If you crank VR-11 all the way up, you can get about 110% modulation with the dynamike set at 10 (8 is a perfect 100% with a power mic). You have a MUCH cleaner, clearer system if you leave the limiter in, and just open the adjustment up. NOW, that said, a CB with the PC-412 mainboard (Like the old 148GTL/2000 & Uniden Grant, Galaxy and the like, or the Export version of the same board), you can do that with. They were built for it from the factory. On the other hand, if you have a different radio, you have to start playing games with the limiter design, or flat out clip it from the system, similar to what you describe. It depends on the radio you are dealing with. Clip the limiter out of an old school Cobra 148 (and others built on the same mainboard), and you will ruin it. 200%-300%+ modulation will wreak havoc with your performance. You will have a loud, distorted, over modulated radio that not only sounds like total crap, but also bleeds all over the place. Trust me, I have built enough of these to know how to do them right (since the 1980s). I don't know what has to be done on the newer 148GTLs though. Those came after my time, and were significantly inferior to the old ones, so I never actually bothered with them. You may have to clip the limiter on those, I don't know.
I have the malaysia model and it wont transmit when it is cold. after around a half hour it comes to life...so it is shelved, but my Grant XL dose a wonderful job
+cordelmar , On a real one, crank up VR-10 all the way. You will get double the power, but the audio volume drops off. To prevent this, you have to crank VR-11 all the way up too. You then get double the power, and double the audio out of it From the factory, they can dead key 8 or 9 watts, and swing to about 16 or 18, sometimes 20 even, on AM, and hit 24 on SSB. They will stay clean, not bleed or cause TVI either. You don't even have to modify them at all, just turn up the adjustments.
I bought a 148gtl made in Malaysia off ebay. R131 clipped, Alc turned up, vr10(am power) also turned up. My dk is 8 watts on ch20, talk into mic it shows a negative swing to 6 watts?? My antenna is a Antron 99 with a 1:1 Swr, 22 amp Pyle power supply. Why the negative swing??
😆 lol. I had an old 148, bought at a garage sale an elderly lady was having. She threw in a black box with fins free. I put it in my f150 with 2 - 102" whips. It was turning tv screens blue for a block. Driving on 290 west at 60mph, I was hitting a guy on a base in Syracuse NY. But, a month later I discovered it was burning my clear coat on my cab.
I wished I had never gave my two thousand to a buddy.. he had it stolen, but i wished I still had it. probably the compositors would have to be replaced.
You have the dead key too high for one thing, and also if you're using an RMS meter it might show 'backward'. It's likely moving forward SOME, but not much. Remember, a 100% fully modulated AM carrier has a peak of 12 watts with a DK (carrier) of 4 watts. You're not going to get much more out of that rig without doing an NPC mod, even still turn the DK down to 2-4 watts - other operators will thank you for it - you will be much louder and have at least as much range as with the 8w DK.
B Henderson I have a 148. It was a good radio. Lost power cord. A buddy of mine got a power cord that plug's into CIG.lighter. When it got turned on. It popes and hasn't worked any more. Do you know any one that work's on them. Would it be worth repairing? If you do my e mail mauldinhogan@gmail.com
Basically a Cobra 2000 in a small package. Provide a beefy trouble free power supply and now yer in business! One of the smoothest sounding receives you'll ever hear due to the dual conversion. Great on sideband. Highly recommended for folks that may not know. Hard to beat. Avoid the Chinese stuff.
I had a Cobra 148 GTL DX about 50 years ago great set
I have an old Philly 148 GTL. I have had it in all my convertible Jeeps.

I ♥ THE COBRA 148 GTL THIS IS A BEST RADIO
I had one of these when I was a little guy. Loved it.
I have Uniden Grant XL radio built Phillipines also built in 2004 radio also open Clairifer and tune up nicely to ! It also well built for plus filters are like HR 2510 10 meter rig and I have adapter 5 pin to 4 pin Cobra with stock mics only needed! Love it 100%
I have a cobra 148 made in Malaysia. Think you for your video it was very helpful
I just picked one up all stock 148 gtl real good condition for $100 bucks made in the Philippines.
i LICK my 148 daily.
it is such a great great radio. i miss the radio so much, and sometimes i wonder if the CB craze will ever come back again.
started 93, and i was such a fan up to 2001, or so,
i spent most of my day behind the MIKE.
lots of groups all around the channels, so many kids, it was fun fun fun.
i loved it. lots of dx ' ing. locals, etc, you name it, mobile operation.
oh well.
:)
thanks for the nice video.
Still licking your 148?
This is the best review of the 148 i've seen. Great job!

i like to see a review on the cobra 146,i hear you can get 20watts out of them i have one solid as a rock on ssb allways on freq,nice audio too.
that was useful, even though i knew most of the stuff. thanks for taking the time to make this. cheers from portugal

Cool story, bro.
Awesome radio. I have the same radio.
That radio actually has a amc pot in it. It is located below and slightly left of the big blue capacitor.I have this same maylaisian radio.
Just to clarify this a bit...The pot that's AMC is it VR7...and if it is, can I just ask...how do you know that please.
If that is VR7, by it on the board it'll be in white/dull white print.
how do you fix the led and the tuner bar
which condenser make my 148 cb Radio run off frequency
I'm looking for help trying to troubleshoot mine.
It was working... but now my channel display is blanked (not visible). Does it do this when the PA switch is on? I thought that might be a clue to what's wrong, if it is?
I was trying to fix a detached black wire inside of my microphone, and when I turned it back on, the display was off. Is it possible I shorted something out?
Help if you have suggestions.
Very informative videos. Love your videos sir. Keep them up. Really Really good stuff your doing for the electronics field.
So is the Pot to adjust frequency for receive transmit or both?
hello I'm a newbie and a friend gave me a tiwan made 148 gtl the radio is five pin but the Mike is four pin and the colours are red,black,purple and braid how do I wire to the radio I'm going crazy here thanks

its not supposed to until you speak in the mic when on ssb, the louder you speak the more the needle will move
THIS radio likely has an RCI-8719 as it is a Ranger made radio. Uniden made radios (Taiwan or Philippine) will have an MB8719.
Looking for a frequency chart for this radio.
I got mine like 30 years ago . excellent radio but it's more like an exciter .
Nice radio k heave a uniden grant xl and it is great too !!
Is it true that ranger now make the chassis for cobra now since they fell out with uniden? (at least that's what i heard)

isnt it a 29 or 26 ltd now?
I got 148gtl-dx Export radio nice radio but the fm on my is disable as well cw too only am model work but it do my ANTENNAS for turn 28 to 29 meter band other that nice cbradio

How do you increase the watts?
+cordelmar ,
On a real one, crank up VR-10 all the way. You will get double the power, but the audio volume drops off. To prevent this, you have to crank VR-11 all the way up too. You then get double the power, and double the audio out of it
From the factory, they can dead key 8 or 9 watts, and swing to about 16 or 18, sometimes 20 even, on AM, and hit 24 on SSB. They will stay clean, not bleed or cause TVI either.
You don't even have to modify them at all, just turn up the adjustments.
Mine was made in Taiwan.

I bought a 148gtl made in Malaysia off ebay. R131 clipped, Alc turned up, vr10(am power) also turned up. My dk is 8 watts on ch20, talk into mic it shows a negative swing to 6 watts?? My antenna is a Antron 99 with a 1:1 Swr, 22 amp Pyle power supply. Why the negative swing??
can anny one help me out my swr is not working can onnyone help me out?
Anyone used a frequency counter on it?
Hardwired?
Me. Galaxy.
it is a shame Cobra stop producing this radio , I don't think cobra is even making a SSB A C.B radio
The 148 GTL is back.. I"ll leave it at that.
ganyan radyo ko ah!! 5 star
No clip🤨
i have one in my truck and i can talk under light lines. i can talk through the tv 5 houses down the street bare foot
😆 lol. I had an old 148, bought at a garage sale an elderly lady was having. She threw in a black box with fins free. I put it in my f150 with 2 - 102" whips. It was turning tv screens blue for a block. Driving on 290 west at 60mph, I was hitting a guy on a base in Syracuse NY. But, a month later I discovered it was burning my clear coat on my cab.
please don't confuse loud audio with good audio is a difference. was the sense of getting way more audio and still sound like shit?
I wished I had never gave my two thousand to a buddy.. he had it stolen, but i wished I still had it. probably the compositors would have to be replaced.
Woz Ya.!!
You have the dead key too high for one thing, and also if you're using an RMS meter it might show 'backward'. It's likely moving forward SOME, but not much.
Remember, a 100% fully modulated AM carrier has a peak of 12 watts with a DK (carrier) of 4 watts. You're not going to get much more out of that rig without doing an NPC mod, even still turn the DK down to 2-4 watts - other operators will thank you for it - you will be much louder and have at least as much range as with the 8w DK.
take it to a radio shop.
138 xlr el mejor cobra
would never remove or clip anything. keep radio stock.
Hm
Mine died!Im sad crosspolarity I think
Fuse didn’t go
All the cobra radios look the same
Keep cobras stock.
Anyone looking to buy and old original 148 with good mods already done?
B Henderson yes, still available?
B Henderson I have a 148. It was a good radio. Lost power cord. A buddy of mine got a power cord that plug's into CIG.lighter. When it got turned on. It popes and hasn't worked any more. Do you know any one that work's on them. Would it be worth repairing? If you do my e mail mauldinhogan@gmail.com
Basically a Cobra 2000 in a small package. Provide a beefy trouble free power supply and now yer in business! One of the smoothest sounding receives you'll ever hear due to the dual conversion. Great on sideband. Highly recommended for folks that may not know. Hard to beat. Avoid the Chinese stuff.
