I’m curious about about your personal protection device in the upper right corner? I’m a truck driver but those personal protection devices are what really does it for me
Mike, What's your thought on drilling out or using a dremel moto-tool to open the mic jack hole on the faceplate and mounting a regular 4 pin Cobra/Uniden/Galaxy Mic Jack? It looks like there may be just enough room from way over here.
Mike, I'm just now watching this, considering buying the radio for actual ham use. (Imagine that!) I run exclusively 10 meter FM above 29 MHz, and have two questions: (1) Is the 455 kHz IF filter surface-mount or through-hole? It's a 6 kHz-wide filter, and I'd like to replace it with 20 kHz for FM use. (2) Is there a way to bias the finals for Class-C? That would reduce power consumption and waste heat, at the cost of sacrificing any ability to use it on AM.
CRT France is euro name,was built on commercial radio Russian markets for business cb uses ie taxi etc as band used different allowed higher power and more channels legally Been out in Uk a while but has 2 fet pa 15w output not high power usa version. they use a cut chassis jig for repairs. radio has narrow fm (2.00khz dev/9khz bandwidth) for European uses & uk use also ctcss/dcs built into radio. pc software quite handy and radio does have vfo function in power up&press certain keys. uk and eu models are 12/24v version hence pcb trace and a screened box sits there but 15w max rf. usa no dc-dc convertor for 45-50watts. Great vid mike,hope info helps. Rob 73's
I have only watched to first few minutes of this video , and I already like it.....I quiet like the design, that includes great RF and heat sinking practices, and the rigidity built into the case design is great.....all in all a good design, and shocks be coming from china.....really looks good.....
Harb's Elecronics Lab The Chinese have definitely been stepping up to the plate with higher quality designs in the last few years. Give it a few more years and they will be the high end manufacturers and somewhere like India or Africa will become the new cheap electronics capitol. Seems like every decade or so a new country becomes the junk electronics supplier and the last one turns high end.
That looks a little bigger than the SR-89MC. Seems that these radios are prone to overheating. My 89 was working fine and then quit, found it way hot. Wonder if the 94s have the same issues?
Mike Ace This seems to have adequate heatsinking for heat dissipation. Main thing is they got the heatsink in the correct location, back to top not back to bottom.
@@mikesradiorepair In many installations, the heatsink on the bottom is the right place, because they're mounted under instrument panels. And it's not heat that rises - it's hot air. The heat from that radio will distribute evenly throughout the aluminum. After that, it's all about getting air to whatever part of the case is exposed.
Mike, I had a similar issue on a run of equipment that needed heat sinking in place to be able to do full testing on the bench.....it was a problem for a long time, and I did a similar thing to your idea with a milled out piece of large heat sink plate.......and although it worked.....every time a new model came out, I needed to make a new piece, as the new design would change just enough to make the one I had useless. I thought I am going to figure this out, so I started to think outside of the square. I know you are also a machinist, so you will know what I am talking about here.........you know those flexible coolant hoses that are made of all those plastic segments that you bend into position to direct the flow of cutting/cooling fluid onto the machining job......well I made up a kind of manifold to hook up 6 of them together, and blew cold air through them, directed at anything on the board that needed cooling.......presto ! I could soak test anything long term with data loggers or logic recorders etc etc that I wanted.....even tested RF stages in TX mode with no heatsinks at all.......I included a spray painters receiver/dryer in the line to make sure no moisture came through....... At the end of the day the object is to cool the heated components, and it does the job perfectly.....I can turn on 1 or 6 with the little taps on the hoses....and best of all it works on everything regardless of board design. and don't laugh, but to get really cold air, I put the little compressor inside an old fridge outside with a half inch hole drilled in the back (to let the air in) and that also had the desired affect of quieting it down too
Harb's Elecronics Lab Good idea. A choke tester could be used to. It's a gizmo used back in the automotive carburetor days and was us3d to test the thermostatically controlled chokes. Hooks up to a compressed air supply and has a hot and cold air output. Works on the venturi principle to make hot and cold air. Would be ideal for something like this,
yeah sounds like the go.....another funny coincidence I was also a Heavy Vehicle Mechanic........worked for Cummins the first 10 years of my working life lol.......funny how much we have in common.
Harb's Elecronics Lab LOL, I worked for International Navistar. Was certified on Cat, Cummins, Detroit and of course International engines. Was still a mechanic when the ISX Cummins engine first came out. It was the new power monster at the time.
I was only Cummins for the first few years and then GM and towards the end Cat at the mines....then my final couple of years worked with Case/International when they took over Steiger......lol....small world........I got out because my back was giving grief.....all the old blokes used to say "son be careful with your back" stupid me didn't listen.....anyway my passion was Electronics all my life really, so I decided to get into TV/Radio broadcasting, became a Broadcast Engineer and the rest is history......funnily enough, all the sitting at the test bench has probably been just as bad on my back as lifting all the heavy cast iron cases and things !!!
Harb's Elecronics Lab Wow, really small world. The last job I had before I started my own mobile service business was as a medium duty Truck mechanic at a Chevrolet dealership. That was mainly 3126E CAT engines in Topkicks or the GM branded Isuzu cab over trucks. I quit when GM decided to go from a pick up Truck style cab to a van style cab. The hoods got shorter by a few feet and the engine got crammed under the dash. Wasn't to long after that that GM got out of the medium duty Truck market. Closed their medium duty Truck plant and sold the P chassis plant to one of the big motor home builders.
Donnie Dotson They were listed on their website when I purchased this radio but no one had the tone boards. Haven't checked recently to see if anyone has them in stock yet.
I guess Im randomly asking but does someone know of a method to log back into an instagram account? I was stupid forgot my login password. I would love any tips you can give me.
@Larry Brady i really appreciate your reply. I got to the site through google and I'm in the hacking process atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
Michael Lloyd I didn't grind into the edge of the board so I'm not really sure. No reason they wouldn't. The price for good quality multi layer boards out of China is really low these days. Elecrow makes very high quality boards and the price for adding extra layers isn't an excessive amount more.
texas range 10 Meter is the amateur band so yes. This is what is known as a "export only" radio. They are not supposed to be sold in the US because they are easily modified for use on the CB band.
cool i was just reading a case of a man who altered a few in tampa to use cb and was pushing 7-8 watts and they were unregistered and he is being fined $10,000 yikes!
Pretty simple silly, make some mini liquid-cooled heat sinks. Heat sink compound is pretty sticky, especially if you leave the jar open for a while. PS it's Majic Smoke. Magic is what makes ICs work. Sometimes if you let just a little smoke out.. The IC starts working again. Yep, you can have just a tad bit too much Majic Smoke.
Pretty much any transceiver that does 10 meters, be it a Icom, Yaesu or Kenwood can be converted to 11 meters by doing a MARS/CAP mod. I would classify this one more towards the amateur radio crowd. I say that because it has a lot of features you would not normally find in what I call "black box export radios". Settings for repeater offset, CTCSS and DCS codes, split frequency, DTMF encode, etc...
I too hate rotary encoder's for that very reason! I hate smooth easy to turn encoders with no feedback or detentes(sp) clicks etc....I want it to be solid feeling and I want tactile feedback when I turn the knob!
I was seriously considering this radio for 10 meters until I found out that it doesn't have SSB. It's a damn shame that they made such a nice radio and didn't include sideband. I'm probably going to go with the Anytone AT-6666. I'm looking for a *real* mobile 10 meter radio, not a glorified CB and the Anytone is as close as I can get. Unless anyone has another suggestion???
THere was a an excellent all mode radio called the OPtima engineered in NzL and built in PRC but they are not advertised any more as new on Ebay. There were quite a few sold in the UK. you will find YT videos on it but you'd have to buy it second hand I am guessing. TE Fidler
28meg & am/fm don't compute. 28megs is usb phone. so only use i see for this is a 27megs conversion where am is acually used but it's all good i wont buy this toy. i hang out os SSB. so to me this is nothing but a fancy paperweight
Scott Edick 10 meter FM repeters are so busy around here there are often pileups. There is a optional DTMF board for this radio so it can be used on repeters.
GREAT REVIEW ON THIS RADIO ALSO ,LIKE YOUR KNOWLEDGE OF UNDERSTANDING AND CONCERNING THE RADIO MARKET WAY !!!
I just bought CRT 2000h version, manual says CTCSS optional but was already fitted, good, fun radio to use. I have seen a 2m version.

Would this radio be compatible with a mic from the anytone 778 ?

Thanks Rob. I may just take a housing and mill it out to make a test fixture.
Yep,that's how we used to do Land Mobile Radio test jigs with Pye/Phillips equipment here in UK.
The manual says optional Bluetooth, does anyone know if the Bluetooth board was ever released? I cannot find one anywhere.

According to the Stryker site they have the tone units for these.
Donnie Dotson
They were listed on their website when I purchased this radio but no one had the tone boards. Haven't checked recently to see if anyone has them in stock yet.
wonder why they didn't include SideBand. Love this radio, but really should have included it.
Hey Mike the ctcss board also covers the dtmf
I wonder if it is plug and play or if the levels will need to be set.
How do you adjust the Strykers power down to use with an old skull linear?

Thank you so much you really help me out :D
@Benton Harley Glad I could help xD
if you had a fan blowing on the board, wouldn't that be enough? Having the strap around your ankle keeps it out of the way...
That looked like a 2-layer board. Is that all it had or is it 4-layer (or more)
Michael Lloyd

I wonder what happens when Citizens Band Transceivers are built around Texas Instruments DSP processors and all processing is preformed using Math.
will that pick up 26.905 ?
will i need an amateur license to use this as a 10 meter?
texas range

Bring a technician license ham can I get 23.800 - 23.599 with this radio after the mod?
Nobody really uses AM/FM that much on 10 meters - all USB or CW pretty much aside from some FM repeaters here and there.
Looks like a good radio for $150.00. Too bad it doesn't include SSB.
Is this not actually a 10 meter"ham radio"? That will be converted to 11 meter freq coverage,
