CAT control a Moonraker Titan V2

[31PAT055]

Hi Ppl...!
I've a Moonraker Titan V2 radio and I'm thinking on trying to make a CAT control for it via UART since the radio has data in/out...
Does anyone already tried this? I would like to have some advice and input on the possibility. My plan is to have an SDR Panadapter for RX and control the radio via CAT control for TX...
Any advice will be welcome, thanks...!

Welcome to the forum!

Interesting concept to try to interface that radio for both CAT control and a pan adapter.

I don't know about that radio but I do know many of the export CB radio's like that only use the USB port for radio menu settings to be set via computer. Also firmware updates can be done thru the USB port too. CAT control data isn't built into the ones I know of but UART is a way to get there if you are knowledgeable about that protocol. It seems to be very complex way to get the CAT control data needed from a CB type radio.

If you use SSB and FM modes and not much AM, maybe consider getting an SDR Amateur radio like the Icom 7300 which already has CAT control built in for easy computer interfacing and it has it's own SDR waterfall display. The radio has an external monitor port so you can see the radio on a bigger screen.

As for Pan adapters, these are fairly easy to interface via an IF tap line from inside the radio or using a simple SDR interface switch box which pulls the RF data from the coax line and protects the radio during transmit with the built in TR/RX auto switch.

One issue with using SDR interfaces is there can be up to a 3dB loss in RX because the RX signal is being split from an IF tap. Probably not so if using a SDR interface box like the one in the pic below. Also there is a bit of latency between the SDR software and radio which is noticeable if you listen and compare the radio's audio output and the SDR audio out from your computers sound card.

Good luck with your project and post it on the forum if you are successful!

I already have an antenna switcher/shearer like that one... what I would like was to make the radio control the SDR frequencies and the other way around... My radio has an UART Data in/out but no CAT control input/output I will try it out anyway. I'm not a ver firmware savvy guy but I can try it out to see if the radio receive external data inputs... Let's see fi I get lucky on my quest... It would be great because there are loads of people with similar radios that would love to do the same thing.
About the advice on buying a better radio already with CAT control, I would love to but I'n'm a budget radio operator and on my current economy I can't afford to buy ay expensive stuff,s so I've to use what I already have... But thanks for the advice...!

Hello.
Forget it. Data in/out is for a different purpose.

I looked up this radio and I see no data port which typically are USB ports. I can't see how this radio (or any current CB/export radio) can ever be modified to have CAT control.

Here is a pic of the back and front of the radio from the manufactures website.






According to the manual, what looks like a data port is for a rear mic input that uses mics with a modular connector.
