Damn, in remember when this channel had about 1200 subscribers. Congrats on the success, well deserved. Thanks for the quality content over the years. All the best Andy mate.
What a great piece of kit and what a difference it makes brilliant. Happy New Year to you.
Very good! Now you can participate in the field day. Please show in the next video how an equally wonderful one of the Begali's key with this wonderful radio and amplifier works.
I use the Mirage BD-35 VHF/UHF amplifier for my HTs. Added bonus during experimentation is that also works on 1.25MHz/23cm/33cm. Only issue was a cold solder Tx antenna connection within which I fixed. Saved purchasing the addition mobile radios, although already had them.
Thanks for your great content. In finland we do have two classes, basic and general class. The basic clas power limits on hf is 120w and over hf something like 20-30 wats, on general class the limits are 1500w on hf and 150w over hf, this is on fm modulation, I can't remember the limits on basic clas on ssb but on general class you are allowed to run up to 600w there is no difference in frequency ranges between classes.
With some exceptions I think it was on 70mhz where there is some different power limits and are actually erp. all other traditional bands are limited to transmitting power.
In finland we do have quite a few hig power repeaters that works well, almost any mobile rig has about 50w output on 2m and 20 to 30w on 70cm
Power is something that does help, but there is a rule of thumb that you should get in the neighborhood off 10db amplification to make it worth the trouble.
What it comes to singnal meters, the 6 db s unit is a very loosely followed standard, and are not even calibrated from the factory even on expensive rigs.
Example Japanese rigs like yaesu use 3db scale on singnal meter.
3db difference in singnal is really hard to hear with your ears. That's what amateurs are using 3db standard in filters and antenna patterns
Thank for your great videos and keep up the good work 👍 de OH2FHJ
Another great video Andy. Very well explained. That’s what you do for our hobby. 73s from the states.
Great vid Andy.. ah my old mate Dave G6TNJ love that little rig..great to see it working on a big twig.. Happy new year.. M0PPK
Thanks for the review!
Love the music at the beginning & end
Thanks for this Andy... I've got a 7300, and a 705. Need to Add the ID-52 to the collection!
Although the amplifier has an SSB button because it doesn't have a ptt line, two things happen, if you stop talking whilst keyed up the amp will drop you out, It doesn't operate on low power but you have found that one out, I have been thinking about getting one for ages but I'm seriously considering Microset which is twice as much moneywise! Great video!
Andy the first great video in 2022 congratulations 73
Thanks for the information of the setup! Cheers from Wichita kansas
Starting to see a common theme here - E-bikes ,E-scooters & ham radio - more power !
I have been using a pair of Motorola amps from the days of the MX radios in the mid eighties. They work great and I can get up to 60 watts with 3watts drive on VHF and up to 50 with 4 watts drive o the UHF unit. One of my favorites is the Motorola HT 1000 series radios. It has a car kit that allows one to set the HT into a holder and it has an external microphone, amplified speaker and the best part the controller ( which originally had an 800 MHz amp which I replaced with a UHF amp from a dead Radius mobile) can provide me with 65 watts out which is way to much for the amp. All I had to do is replace two surface mount resistors on the rf attenuator circuit on the input of the amp. Now its at 50 watts. Now if I only had one of the wide band JT1000 radios to use with this set up.
BTW, all of this is using USA radios in the USA.
Also works with DV/DMR as I tested it with my Retevis RT3S (TYT ND-380G).
RM Italy is a great, innovative company with many good models. Use their KL501 HF 1.8-30 MHz amplifier for my Yaesu FT-817D bought demo from ML&S. Only issue had was it needed 4AWG cabling and/or direct hookup to a large automotive battery.
Bit o' binge watching Andy, like the radio...Thanks
Hi Andy , happy new year , with regards to antenna gain and ERP, because nowadays antenna manufacturers use dDi as it looks if it’s more gain for selling point of view , actual fact that antenna gain is dBD ie db respect to a dipole with us the reference, if an aerial is says it has 3dbi it’s not 3 db gain or x2 , it’s actually 3dBi - 2.15 = 0.85dBD gain at the antenna connector at base of the aerial. So ie if the antenna for example is 5dBi gain that is actually 3dBD gain and if 10w applied to that aerial base then the effective radiated power is 20w . I hope this helps . Great video and that icom handheld looks really great . 73s de Mark G8RDE
I’m into GMRs since my area has quite a few repeaters. Running a 45 watt radio with a beam I’m reaching repeaters 50 to 70 miles away. just for the heck of it bought a Chinese 80 watt amp off eBay which put out Around 65-70 watts and it didn’t make enough difference to warrant spending the money on.
I’m now a believer that the antenna is the key.
Thanks Andy, all interesting and helpful stuff. I want to do my intermediate license soon too.
Cool, there's a section in the intermediate manual that talks about this stuff. Glad it was helpful.
@@andykirby Yes, that's good to know. I have got the intermediate manual ready to study. Mind you, like you say, you can feed up to 10 watts into the antenna on foundation. So my 9dbi UHF Yagi is radiating me out 64Watts ERP from my 8Watt Baofeng GT3TP. But it would be nice to have those extra few watts if I need them once I get the intermediate sorted. :)
Yes exactly, 10W is enough. I wouldn't mind the 23cms allocation that the intermediate brings and also operating abroad which I think you can do in certain countries without needing a full license. Ultimately I'd like a full license eventually anyway!
@@andykirby Yes, it's got to be done a full license!
@@andykirby 23cm is something i want to do and as you are so close to me it could be fun :) only full calls can operate abroad I believe :)
Great video Andy. Happy New Year. Motters M7TRS 73
Good work there Andy! How much powerare you alowd to use on 2m in the UK? Here in Norway we can use max 300W I think. Happy New Year Andy. The best from LB1NH.
How do you see the activity on the screen I think that's useful do you no if you can do this with the ALINCO DJ-MD5XE, I also would like to use it as a home base, thanks in advance.
Wow Love the waterfall on the Radio!
Do you used an ATU on the 705 or use 2 antennas? Happy new year 🥳
That is a nice power unit.
Nice video. Who makes the amp?
Andy another good interesting video, where did you purchase the stand, radio holder and amp?
The stand is a mini camera Tripod amzn.to/3qMjGty with the smartphone grip. The amp is an RM LA144, Google for results.
This little radio is becoming more and more interesting.
Thanks for all the information and your music is getting up
there 😎 with likes of Armin van Buuren in a State of Trance.
Just out of curiosity which way did you have the fan.
Was it blowing air on the heatsink or was it pulling heat away from the
heatsink ?
Thanks mate👍🏻 the fan is blowing onto the heating haven't tried it the other way.
Hi Andy, I was looking for a stand that worked on my id52, but all seemed a bit short length in order to cover battery and body, Could you please tell me which one you are using . It seems quite still. Thanks in advance. 73
That’s awesome Andy, I’m thinking of getting myself one as I’m using a mobile unit as a base radio for now. 73s from 2ED503 🇺🇸
Ooow i want one, so many possibilities
Where did you get the radio holder Andy?
Great video
i like your icom..Very nice man
What PSU are you using with this?
And what does the 70 watt amp cost you guys? I would like to buy one whT is the name amd model number of the amp ?
What kind of power supply is that?
Hey Andy, did you manage to upgrade your license?
Have you grounded your Diamond x50?
Hi Andy just wanted to know if u was selling any of ur e scooter as I'm looking for 1 meany thanks
Oh that title will get a few going. 🤣 All the best Andy.
Just for 2m or 70cm too?
How do you like that antenna? I'm thinking of getting a dual band antenna for my house but didn't know what to go for. I'll be using a handheld mainly to start with. Thanks for the vids mate great work 👍
Those antennas are fine. I have the smaller model which is the Diamond XL30 and it's perfect for me. My only advice is buy the Diamond brand and not a copy.. 👍
@@benpatsy2076 thanks mate. 👍🏼
Moonraker are doing the sharman x200 £59.95 atm it’s the equivalent of the diamond x200 which is better than the x30 and x50 only a lot cheaper
@@Superfandangoo oh really? I'll have a look now thank you very much👍🏼
@@DeeMcQueen plus 8.99 next day delivery dhl, you’ll notice your receive is a lot stronger with these good luck
what try pod phone charger
Do you get interference when using the USB charging ?
Yeah you do... not sure if it comes from the supply or the internal charging system.
Another advantage is to install one of these amplifier units (hidden) in your vehicle, so there is no fixed mobile radio to get stolen.
Why are you using lossy rg58 at 144mhz and above? First thing I would do, is scrap rg58 and use decent cable to reduce any cables losses especially at vhf frequencies, plus it will reduce interference.
It's a temporary solution and so is the mast in the garden. This is my temporary location. I usually use M&P Ultraflex 10. Actually I was surprised how well RG58 worked.
@@andykirby RG58 is fine for shortish runs, I've never had a problem. Although I do use RG213 for anything over 10Mtrs on VHF and above. You hardly notice any losses with short runs.
Andy what coax are you using from the radio to the antenna?
Simple RG58 nothing special.
@@andykirby lossy
@@andykirby just 15m of rg58 on 2m loss half your power on 70cm 3/4 of power loss, remember 10w PEP is out the radio into the coax not the antenna feed point. And just 1 meter of that rg174 on uhf has a 1.5 watt loss.
LMR400 will sort you out on tx & rx
Andy, what pole did you use for the x50 mate?
It's a telescopic fibreglass pole from moonraker, expensive but very good if you want to do experiments with different antennas etc. It can also rotate/twist so you can put a beam on it.
@@andykirby spot on Andy. Will take a look. Thanks again and keep up with the videos.
Andy ay up mate, love the vids Andy and inspired by you, Fred, DX comander and Lewis plus many other tubers i took and passed my foundation licence test on the 21-12-21 [great date, all 2's and 1's] just thinking now of a proper antenna and i know you run a Diamond 50....do you rate this antenna and is it your main home base twig....i'm an engineer and over the past 2 years of covid i've made many an experimental antenna, to include, inverted v's dipoles co liniers, etc etc ..but from my home station was thinking of a proper 2M 70 cm commercial y bought one. ..many thanks for your thoughts mate....happy new year and 73's
Hi mate, well done on the foundation! The diamond x50 has become a bit of benchmark antenna, it gets the job done reliably and they are built well. I also like building antennas😁 but you cant really beat a commercial antenna like this for its weatherproofing and just reliability. Take a look at the other diamonds like the X200 and X300, they are a bit longer but provide a bit more gain, I'm tempted to try one myself!
@@andykirby cheers mate, and thanks for the response. have you tuned the x50 down to other bands at all. just to save having numerous twigs on the roof...ta mate any way, love the vids.

Can you get the CB radios bands on icon
Not on a 2/70 handheld you can’t
Is that a multimode ht? Ssb Fm Cw?
nope.
Great job what is the brand of the amplifier ?
RM Italy
@@forgetyourlife thank you
ic705 draws 2amps at 12v on FM at 10 watts output, as reference (I have one)
I thought it was, not a lot different to 5W, its super efficient.
Be careful of too much power reflected back to radio. In a bad SWR event your radio will not like the Higher than normal return. Best to ensure the SWR is flat. Hopefully the Amp will absorb the extra.
SWR was 1:1 did you see the meter?
@@andykirby newbie HAM, @william was referring to a “bad” scenario..normally you have 1:1, but if something were to happen where SWR changes without you realizing…
Please be careful when connecting a handheld to a base station antenna like that, static charge build up from the antenna blowing in the wind can be enough to kill the radio
Interesting, surely this would affect any radio? Not just hand helds? What's the best solution? Earthing?
@@andykirby yep having a path for the charge to go is the best solution.
I'm sure it does affect any radio, handhelds seem to be more susceptible to it, probably because they were designed to be used with smaller rubber antennas
This really isn't the problem people make it out to be, I had a yaesu ft23r handheld continually connected to a roof top antenna running my tnc and packet radio station for 20 years until I moved house, the radio still works 100 percent and it's receive sensitivity is still per the book, fact is your handheld is far safer in you shack, it's far more likely to get broken stolen or lost when you take it out, just enjoy the radio what ever you do with it.
Dont tell ringway Manchester about the burner
I had a hand held I put on a beam and was talking all over the place
I got a speaker mic for mine from icom so expensive for just a speaker mic 85 pounds
1:14 that's FT8 on 144.175
Yes.
My Step Dad who was an illiterate 6'5" 250 lb man that could give a Fuk had an antennae like that an would crank it up as he was runnin 50.watts ..lol
This is 1978 an it would kill all t.v. an radio to home for Blocks ... Too funny an thx for memories
Sounds like a real jerk running a poor station with lots of bad RFI. Television isnt on 2m so im guessing it was either 11m or most likely 6m which was right on the TV band at before the digital switch over.
@@forgetyourlife it was 1976 sunshine 🌞
@@JayTalksinjury physics were the same in 76 as they are now.
What can i say he was 6'5" 260 lbs an that jerk would hammer your ass into the ground .. fyi
@@JayTalksinjury cool, My family could use the money.
I don’t get that S-point argument, two S-points is massive, if you're a very faint signal just above the noise floor, two points up brings you into a very strong readable signal, on SSB.
CW might be different, I don't use CW like 90% of operators.
10 Watts. Who are you kidding? More power is almost always better; higher S/N
Andy's next amplifier draws that much he has to notify the national grid when he uses the radio so they turn on another power station.
Hold on, that's wrong! 5w in to the antenna, fine. However, the antenna cannot make it magically 10w! The gain of an antenna is in its directivity compared to an isotropic radiator!
Correct, I said 10W out of the antenna I didn't go into how it is radiated. I tried to keep it simple.
@@andykirby OK, I'm trying to get into FM 2m and 70cm myself. Last time I had a handy and only got Dutch locals complaining about traffic! Interested in trying to catch some satellites this time around.
@@andykirby you meant ERP :) right :)
I think you should make clear that while only 5 watts is coming out of the antenna, that it will SEEM like you are transmitting at 10 watts to other people who are listening to you. I say this just because I'm sure a lot of beginning and aspiring hams benefit from your channel, and it can be difficult to get all of these things straight.
not in to radio stuff hopefully at some point there will be some other content
Get a radio and mess around.. it's a lot of fun..
@@mixxndj why would I waste money on a radio when I have no interest what so ever in this type of communication, I have a perfectly good phone and the internet to communicate world wide.
