If I use software PL/CSQ decoding, I was getting reports of something coming back from the node after they unkey. Turning RXondelay up to about 6 (6 increments of 25ms) it worked great until I tuned to the bottom of the 2-meter band and I had to turn it all the way to 15 to avoid problems. It's fine unless someone quick Keyes and then I will loose the beginning of their voice. This is a simplex GM300 node, so I am guessing there is a lack of high frequency noise immediately after I unkey. What I don't get is why it is worse at the bottom end of the VHF band. I guess the VFO is sick down there and takes longer to activate? On my UHF GM300, I can get away with rxondelay set to 5 at 446.000. I haven't tested lower, but I won't be transmitting below 445.0 There is a variable inductor that I found near the receiver chip which actually improved tuning it from what I was initially getting, needing to set rxondelay all the way up to 25. (It's near the squelch pot) I am going to use COR from the radio anyway so I won't have the problem, but I was planning on modding one for 9600 baud which could never deal with the horrible TX/RX switching time that I am getting. Any experience with this issue here? Also, It's annoying that I have to run rxondelay, I wish it could just ignore the receiver immediately after the transmitter drops, no other time. Is there any other setting? 73 Skyler KD0WHB -- Skyler Fennell amsatnet.info KDØWHB electricity440@gmail.com
I have never had this issue and I run mine on DSP. Discriminator on rx and flat tx audio. Corey N3FE On Wed, Jun 29, 2016 at 11:20 AM, Skyler F <electricity440@gmail.com> wrote:

Huh. I am running discriminator and flat TX. Did you ever test it simplex or was it only full duplex with two separate radios? On Wednesday, June 29, 2016, Corey Dean <n3fe@repeater.net> wrote:

Many ways actually. I have used it simplex like this and I have used it as a remote base using link2link, and at one point in time I was even using the steering lines and using it as a remote base. I have done this on both VHF and UHF. Corey N3FE On Wed, Jun 29, 2016 at 11:26 AM, Skyler F <electricity440@gmail.com> wrote:

I'll post my usbradio.conf when I get home in 30 minutes. Do you mind sharing yours for a simplex gm300 node using DSP if you happen to have it? On Wednesday, June 29, 2016, Corey Dean <n3fe@repeater.net> wrote:
