Regarding your question about 40 watts on AM, that is the absolute PEP (peak envelope power) design limit of the output stage. 10 watts carrier with 100% modulation results in 40 watts PEP (or "swing" as CB-ers call it.) That is the reason for both the 10-watt AM carrier limit, and the slightly conservative modulation setting. Increasing either power or mod level in this radio is rolling the dice on Chinese semiconductors. The factory also rates the radio for up to 5% distortion on transmitter modulation as delivered stock ; this can result in PEP slightly higher than 4X carrier power if mod levels are increased. Increasing carrier power from 10 to 40 watts is only 6 dB, or one S-unit difference at the receive end, while creating a ton more heat in the radio. Chinese parts hate heat! Better to use a separate amp and mount it somewhere you can dissipate the heat. FM can allow a 40-watt carrier setting because on FM, only the frequency changes with modulation, while the PEP remains constant at the same level as the carrier.
This TCVR appears to use the RD16HH part x 3 as the RF PA and they are rated 16 W a piece. Moreover they can be bonded down to the case with no insulating washer because of the internal design. I think your comments might be misplaced for this particular radio tcvr. For other Chino tcvrs I tend to agree... TEF NzL IN this particular radio I DON"T see the Mitsub. logo on those MOSFETS ,which is a worry... the logo looks a bit like Fairchild which suggests a lower grade substitute. I suspect this radio was Badge engineered and the Stryker factory has no real say in the quality. I definitely saw the Mitsubishi and RD16 on the other strip down..... so it goes.
Just in case anyone else runs into this issue; if you select "CB only" or whatever the menu item is after cutting the wire, you will not be able to change the power from 4W to 10W, it will just say "Error". Select the HAM mode and then you can change it.
****** Thank you for the video, just bought this radio from amazon and did the mods according to your instructions !!...fast and easy !! :-) :-) ******
I bought my second 94HPC and searched your video for a refresher. I also fully removed the white loop wire so there is no way it will touch. It's a great radio for the price and it's going in the dozer I run since it's a tough bugger. It will replace the 25MC that is going back to Bell's for a tune up. Also a nice 27mhz converted and smaller
There is a setting available in the PC software Function Setup > Auto Power or via the menu FUNC MENU > AOP which configures whether or not that the radio automatically powers up when power is applied
I'm in the UK so EU Market for me, I have the same radio named CRT 2000H, the 2000 is 1-12w and 2000H 1-40w Hp version. I also have the CRT 2m/70cm radio which I opened up which is the same board and completely the same design, just different bands. Only thing this radio is missing is Ssb, it would be a great little radio, and 40w on the nail UK40FM. Also have the 6900N/9900 both CRT Q5/Q6 to you.
When I select the CB only conversion, there's an "EU" displayed with the channel. Is that European Union frequencies or does it represent something else? Thanks.
I believe CRT 2000h is the HP version of that SR94, can also be opened up for 10m, happy with 11m Ssb. You'll always get more watts on Fm over Am 🤷 they're great little radios though.
On ham radio the frequency standard ends in a zero instead of a five. Does this switch to a zero when going into legal ham bands while running modded for all? If not how do you change to a zero and still keep a 10k step?
The best would be a 102" whip, but most don't want that on a sedan, or are prepared for the larger hole in their vehicle trunk. Short of that, a K-40 (with maximum length whip) or a Wilson (max whip length) Both can be mounted in various ways....mag mount, side mirror, trunk ....etc.
My question is this: Will the same mod work on the Anytone 778, which is opening up CB frequencies, and also, will this mod on the 778 also open up GMRS frequencies? (Transmitting)
Simonthewizard has a video that briefly touches on the mod. Maybe you can see which solder connections to change since you have your radio in hand. I ordered one, too, with the intention of converting it. I should get it tomorrow, I hope. There just aren't and sites or videos releasing this information yet for some reason. Send a comment back if you've located anything useful. It would be appreciated for sure.

Now-a-days there isn't a lot of activity on the CB band. If you want to hear folks talking you pretty much need to discover which channels are the most used for your area. Around here, (Portland, Oregon) channel 17 is pretty active. Then totally open the squelch and just wait.
carlos barajas of course you can but it'll probably be noisy when the car is running if you don't run it directly from the battery if you have no filter. It comes with a 10 amp fuse inline
I have seen one opened up and it looked very similar. Row of three mosfets down the LHS for example. That one was BOUGHT as a Ham radio tcxvr so the owner had not much interest in changing it over to CB. If you look for Ytubes on this model number you should find an English guy messing with them and you'll likely get your answer. ... Sorry I can't recall his name but he's a pom./Brit.
I have 2 CRT 2000's and there is no need to open them up (UK spec), simply hold [FUNC][P6] then press [power] and you get straight to the 3 mode options. Running on HAM mode as came set to CB as standard (simple AM and FM is perfect for road trips). Not an ounce of electrical noise from my vehicle electrics either. MM7DSV.
@@georgehaha6969 may I ask a question. I just brought one of these expanded. It's the 2000h. So your telling me if I wanted to listen to ham I have to turn of and press 6 or whatever and turn back on. There's me leaving it on fm and going through loads of channels hoping I could hear someone.. I use it mainly for CB UK but would love to hear ham etc.
@@mduffy5453 Absolutely, there is now no need to lift the lid and cut any wires. Our 10m amateur band is 28MHz to 29.7MHz but you will only hear FM between 29MHz and 29.7MHz due to band plan restrictions. Depending on where you live it may be very quiet just now but during the summer it is affected by skip just like CB. Happy listening but please be sure NOT to press that key, probably safer to unplug the mic when SWL (Short Wave Listening) to this band. Ohh aye, be very careful if you set to the 3rd mode 25 to 30MHz because from 25MHz to the CEPT CB band there are allocated frequencies for paging systems, global marine comms and search and rescue.... not forgetting RC cars and aircraft. Hope this helps, now known as 2M0FUP.
@@snippits75 Rubbish. There is continous carrier on FM - that's why Vox operated PAs can only work if you can find a PTT line from the driver radio. The issue is that on AM the efficiency of the PA drops as it can no longer be in class C mode. The 40 W PEP I call as BS. The PEP of an Am radio is virtually never more than three times the carrier level. 30 W is more reasonable as the PEP. This corresponds to about 3.6 W out on a small SSB transmitter in terms of RF punch. ON air tests show that the intelligibility on AM mode of this tcver is Worse by a long way than the same in FM 10 W mode. TE Fidler NzL
@@HippocratesGarden For those of us just getting into it, the op asked if it does SSB and you answer am/fm only.. is that a yes or no to the SSB question ?
No im not saying the radios not modded, I did the mod myself. But for those who didnt do the mod, you just show the modded menu. To truly show that radio is successfully modded, you should show an expanded channel. Also you can change the power on automatically in the menu system. I know you want to keep the video shorter, but for those who havent done the mod, a modded menu is not proof that the mod was successful.

How about doing a video on the SR 25MC? No wire to clip, but moving solder connections instead.
Not true. You go past the NULL page or screen. Next screen is the Citizen Band. I did mine, and everything works including 4W.
I got a CRT Dual Bander just the same & to open up the radio it's P4 & P6 while powering on 👍

Will this same mod work on the Midland DBR2500 since it looks like the same radio?
I don't think the Midland version has the same board. Similar, but not the same.
no ssb no want
needs ssb i agree.
Hmm ssb in your car, interesting..
It’s advertised as a 10 meter radio. The only activity for am/FM is 29.0-29.7? I think it’s a waste without SSB.
