Hi James, Chuck Henderson, WB9UUS, made a couple modifications to the code... one I believe actually fixes a bug in how the RSSI is calculated (which is probably your issue), and the other changes squelch action. A previous thread here: http://ohnosec.org/pipermail/app_rpt-users/2016-June/014314.html If you look in the source code, you can find the specific changes: https://github.com/AllStarLink/voter/commit/9e6938a0bd19db9477fcb15bf15820d9... The predominant issue here was even if the received signal was full-quieting, if it was a short transmission, it could cause a long squelch tail. As for how the RSSI is calculated... if you look at the RSSI in Allmon, without this patch, you'll see the RSSI level jumping all over the place, especially on noisier signals. With the patch, things are much more stable. Firmware images with and without the patch enabled are available on the repository for you to try out. They should be there for all hardware flavors: https://github.com/AllStarLink/voter/tree/master/board-firmware If you are using a MicroNode RTCM, you will likely want the "SMT V1.5 Chuck" file.

Firmware version 1.50
I guess I am not familiar with a "Chuck squelch patch" so am guessing that I am not running it! Can you help point me to information?
Thanks!

Hi James,
What firmware are you running in the RTCM's? And are you running firmware with the "Chuck Squelch" patch enabled?
