Re: MD-9600 / RT-90 Installation

Hi Folks, shit happens... I have opened the MD and found something strange under a capacitor... solder residue. With the official Firmware the TX output was given. But after handling on my desk the solder has hiked under the capacitor and caused a short cut. Removed and V2 FW works perfectly now. Th...

Re: MD-9600 / RT-90 Installation

Hello, now I have a MD-9600 from a friend. On the printed board I can read Hardware V2.1. I have tried to update with "MD9600-CSV(2571V5)-V26.45.bin" as DMR donor firmware and then with current "MD9600_firmware_V2HW" but no TX Power comes out. The screen counts up seconds as normal. Then I have trie...

Re: MD-9600 / RT-90 Installation

Dear Colin, sorry for my mistake. I saw the ZIP Filename "210525 MD-9600 V4 firmware for PLL2571" and was not aware of V5 FW inside. It´s phantastic. All works fine now and I have my GD77 and RT3S Codeplug on the RT90 now. Thank you very much. One question. I have never worked on DMR direct frequenc...

Re: Hardware Version V4A GPS

Hello all,
i just have got a new RT90 with V4A marked on the board inside. Where I can get the V5 firmware version? The EA5GK links do not offer that. But some guys apparently have flashed this version with success.

Re: Larger memory

Hi all,

I have opened my RD-5R and found an 8Mbit flash memory 25Q80DV. Did anyone try to replace this flash with a 25Q64xx or 25Q128xx in order to increase the memory for DMR IDs?

Best regards

Re: Larger memory

Dear Daniel,
I have fitted another GD with a 25Q128fvsg according the methode I described before. No problem at all :-). It seems to be a difference between the FWs and/or the CPSs.
