Re: [App_rpt-users] Squelch issue with RTCM and Kenwood
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, 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.

Always wanted to "play" with voting system and maybe simulcast. My primary site is on a wireless network that belong to a ham friend and he provide me with the bandwith and I use some IP in the 44.xxx.xxx.xxx range. He have a site where I could install a voting receiver. And I have a site where I could simulcast. the computer at the main site will be changed in the next few wek to a proliant dl320 g5p with 8 gig of ram and 3 tb of hard disk. It will run Dial and Xen, cause I want to virtualize some service for our Mesh. ( web and file server. asterisk for local mesh voip. and stuff like that. Anyone built there own voting board? I made many pc board in my life and want to maybe make a few to test all this. Is there some gerber or SCH files available to build a voter board? 2017-05-01 12:28 GMT-04:00 Lee Woldanski <ve7fet@tparc.org>:

The RTCM will have longer squelch tails on weak signals or quick keys. Be sure to set the squelch at least 3 full turns above threshold. You want it to be around 350 or more on status menu 98. That will help. Not sure if Chuck squelch will help. If you try it please post your results. On Mon, May 1, 2017 at 1:38 PM, Pierre Martel <petem001@gmail.com> wrote:
