Re: ALPHA 2022 11 02

I own a GD-77, but not a RT-3S. I apologize for my ignorance, but I think that I need to have a RT-3S or MD-UV380 to do a screengrab within the CPS. Hi, Could someone please post images of the RT-3S display with the OpenGD77 firmware installed, in both normal and inverted? If there is a difference, ...

Hi, Could someone please post images of the RT-3S display with the OpenGD77 firmware installed, in both normal and inverted? If there is a difference, could someone please post the same for the MD-UV380? I looked at Roger's videos on YouTube, but was looking for static images, if possible. If they a...

Re: RT-3S Zone, Scan list, Channels & Frequency Range Questions

I just went through the CPS. I was confused because everything says GD-77. I noticed that you choose radio type for the RT-3S. I was also able to confirm that there are 80 channels per zone max and that there are no scan lists. Now that I think that my questions have been answered, which radio shoul...

Re: RT-3S Zone, Scan list, Channels & Frequency Range Questions

Thanks for the info Colin. My GD-77 receives up to 512 MHz better than any scanner that I own, so that should be good. Could you please confirm the number of channels per zone, per scan list? Also, did you eliminate scan lists as was done in the GD-77? Is the CPS the same for all supported radios? A...

Re: RT-3S Zone, Scan list, Channels & Frequency Range Questions

On page 6 of the Retevis RT-3S user's manual it says: "Zone Selection Zones is a channel group. Each radio can set 250 zones and each zone with max 16 channels." Page 45: "Scaning List Create a scan list and assign a single channel / talkgroup, your radio can support up to 250 scan lists, each up to...

RT-3S Zone, Scan list, Channels & Frequency Range Questions

If I remember correctly, before OpenGD77, the GD-77 was limited to 16 or 31 channels per scan list and/or zone. Also, the frequency range was limited to either 470 or 480 MHz and the scan speed was slow. I believe that in stock form, the RT-3S has similar specs. With the new development updates for ...
