OpenGD77

Hi, Won't work. To use the OpenGD77 CPS, you have to flash the OpenGD77 firmware first, then make the backups. Cheers. --- Daniel Thanks for responding. I am now trying to do what you say using Open GD-77 CPS but it always fails as it doesn't see the radio. 1. I get the firmware download ready to t...

Hmmm, I'm in exactly the same position, I think I'll try checking the cable and uploading the Open GD-77 firmware.

I'll jump in angain and clarify my situation... I just got a new (open box) Radioddity GD-77 and, on the advice of kt4lh, I was aiming to switch the firmware over to Open GD77 immediately so here's where I'm at: 1. I have a virgin GD77 (I presume) that has never even had a code plug written to it 2....

Thanks, I just got a response from Radioddity saying that I should see a USB device named MCU MOUSE DEMO which I do . I also have a Baofeng cable (for UV-5R) that uses an FT232 driver chip and comes up as a COM port, will that work for the GD-77? So far, I have only installed the Open CPS applicatio...

I'm running Win 10 and I'm pretty IT-literate. The Radioddity serial cable is recognized by Windows if my GD-77 Radio is power on but there's never any Com port - it comes up as USB Input Device - so Open CPS can't read or write to the radio. I tried downloading the driver on the Radioddity site but...

I don't have my GD-77 or my hotspot yet but they are on the way. I'm researching how to set up my GD-77 and have a couple of noob questions: 1. The FAQ says Q. If I install this firmware can I return to the official firmware A. Yes. But only if you backup the Flash, EEPROM and MCU ROM data, using th...

Thanks, you made that really clear. The detailed instructions for Open GD-77 also seem to make it clear that I can jump straight in and install Open GD-77 firmware on my GD-77 (when it gets here) using the Open GD-77 version of CPS and then backup the flash so I can revert to original firmware if it...

I'm just starting out on the DMR journey and thought I'd try the Open GD-77 route. A few quick questions please: 1. How do I test that my GD-77 is working OK before I install the Open GD-77 firmware? 2. Do I need a special version of the PiStar software installed on my Pi Zero 2 W-based hotspot to r...

I went to www.radioddity.com today and, on the first page there's an 'Open Box Sale' at the lower right. Click on that and there are a few GD-77 open-box radios available (at time of writing it said there were 11 left in stock for $85 each). I also got a $10 off discount for being a first time buyer...

Then I moved to the USA in 1997 and now live here, have just retired, and hold the (vanity) Extra callsign AB6B. If anyone I knew in the UK wants to get in touch, please feel free to rea...
