There is a way.
Here is what I know. They are set up a lot like an export. They can take an NPC mod. This radio was a pain in the @ss to figure out because the board is a multilayer. We have it doing 30 watts PEP with clean modulation and have figured out how to lower the dead key to 1-2 watts with the same 30 watts PEP swing. The audio is VERY anemic out of the box! It took some time to figure out how to open the audio and make it right, not flat topping, but we have figured that out. It uses a common TDA2003 audio chip. The audio on this radio is like digital. The radio transmits the signal a split second after it has been processed. Therefore, the talkback takes a little getting used to. It will really mess with your head if you listen to it on a monitor radio. The echo is OK as is the talkback. Not the best, but for the price, what do you expect? It will accept a dynamic or elect mic. It has 6 gay roger beeps built in. You will not hear them in the talkback unless the key beep is on. The most un-annoying one is 6. The echo sounds good at 2 volume and 2 delay. Like most of the radios built by these guys, including some of the Stryker Radios, the talkback does not exactly represent what you hear over the air. If you set the echo level to what sounds good to your ear on the talkback.......no one will want to talk to you because you will sound like a total d!pSh!t, Freightliner Crapscadia driving, wannabe Chicken Haulers that like to play hide the pickle with his male codriver. Simply put, its WAY overdone if you don't know where to set it! Simply move the jumper on the PCB to obtain 10 bands of 45 frequencies. A dot will appear between the 2 digits in the display when you are on an alpha channel. When we do the "power modifications" to it, it does not like the wide pool of frequency. It falls on its face after 20 channels either direction from where you center the tune of the radio. I'm sure there has to be a hidden menu in this radio, but we haven't figured out where it is or how to access it yet. This may rectify the situation with the power, but I'm not sure. There is also only so much you can do to the power because the radio runs on a regulator. It will support 12-24 volts which is awesome because you can easily hook it up to most heavy equipment without purchasing a stepdown converter. We did get more power out of the IRFZ24N final in it, but we had to bypass the radio voltage regulation and volt the final. Doing this will not allow you to put up to 24 V input into the radio. Frankly, it wasn't worth the time to do that and it was only done on our testing radio and we have since removed that mod. We have been beating the hell out of it on the bench for the last 3 weeks to work out the bugs. I like the square inductors in the PA section. It has a settable SWR bridge that will flash warning when the SWR is over what you set it at. The VOX is actually easy to use. If you are in a noisy truck, you will want to probably wire a noise canceling mic for it and turn the sensitivity up to about 6 or 7. The weather function is spot on. I like the operation of it. You can set the PA to different functions. It has the ability to change the display to different meter types. The mic it comes with is elect. It has the same wiring as cobra 4 pin but you can add a switch to change channels like you can for a Stryker if you know the secret sauce. The stock mic is very sensitive. It can pick up a fly fart at fifty feet. The 7808 and 7805 regulators run VERY HOT. My test radio has TO220s mounted on the chassis wall. 180 degrees on the 7808 IMO is way too hot. For the guy wanting to put in the ammo can, just simply remove the face and mount the face in the side of the can. It is easily made into a remote head. Your "cut out", fold the metal inside the box and use 4 screws with spacers to mount the head to the can, use the mounting bracket to mount the radio inside the can to the inner wall.
That's about all I can say about it. 73s
