Re: FYI - GPS

Hello everybody! Finally! New GPS antenna installed. Excellent results! 28db antenna, installed on top of the radio. When activating the gps, in one minute the gps starts to receive the satellites. Amazing, I wasn't expecting it. Indoors, he obtained 9 satellites. (And with the exact location of my...

Looking back and THANK YOU

When I decided that I would get into DMR I chose the GD-77 for two reasons, cost and the OpenGD77 firmware. At that time I never thought it would reach the level it has and continues to improve in both function and features. I purchased the MD-9600 mainly due to cost reason, plus it had good reports...

Re: Follow up on GPS for MD-9600

I have an external GPS attached to my MD-9600 via a cable from the back of the radio. This cable is connected to the GPS connections in the front panel PCB of the radio and runs over the top of the PCB and out of the back of the radio through a hole in the heat sink. V4A aka V5 hardware radios have...

Follow up on GPS for MD-9600

I have been reviewing the thread on the MD-UV380 / RT3S GPS upgrade or addition, plus the one thread on MD-9600 new antenna install. I am curious if there is anyone who has installed GPS into MD-9600 that did not come originally with GPS. Also it has been mentioned in the past about adding a 3.5 mm ...

Re: DMR Data Mode

The firmware does not support any pure data modes. Various developers have attempted to implement SMS / Text data but have failed to do so, due to the lack of documentation on the DMR chip used by these radios, and also because some of the SMS / Text formats are either priorprietary and protected b...

DMR Data Mode

One of the things that has had my interest about digital RF communications via radio is the possibility of 'DATA' only modes. Not going to get technical or such, but the idea of connecting a radio that has DMR to a computer and sending information between computers using the DATA mode of the DMR spe...

Re: Possible Feature: Setting to control RX gain

Jumping in here. In the Fox Hunt I am assuming you are using something like a 2 or 3 element yagi as your antenna. If so when the RSSI goes full scale you could add an inline attenuator, Say 6db or so. Not near as nice as having a radio that can adjust the pre-amp dynamically but practical and doabl...

Re: New CPS 2023 08 18

So you need to update your radio firmware before updating to this version of CPS Just to be extra sure and careful I should update to the latest firmware on the radio(s) using the CPS I already have and pre-dates this new CPS. Once I have updated the radio(s) firmware only then should I use this ne...
