[arm-allstar] Transmit PL on Simple USB

[David McGough]

John,

Since you're hearing a birdie on transmit, that implies VERY close
proximity to the Quantar.  Is this repeater ultimately going to be 
deployed at a remote site??  If not, wouldn't the simplest solution be to 
reprogram the Quantar to a different TX/RX pair and just avoid the birdie?

Another possible solution would be to program the Quantar to have a 
separate signal to enable TX PL tone. Then, you could use the TXCTCSS 
capability in simpleusb now. Using this mode, a separate TXCTCSS signal is 
generated and follows RXCOS, etc.

My repeater does send PL on transmit, and my HT that I use to talk on my 
repeater has receive PL working. My Quantar controller emits a very 
strong birdie on the transmit frequency, a signal that my RF squelch 
won't mute on my HT at any setting. Only PL squelch works. However, PL 
mute still takes 1.5 seconds, making me listen to annoying digital noise 
for that time every time my repeater unkeys. Thus I'd like to set my PL 
to drop 1.5 seconds before the carrier.  Hope that makes it clearer, and 
PL from the Pi would make this easy.

Thank you for your replies.

My repeater controller emits a rather strong birdie on my transmit 
frequency.  My HT finally mutes 1.5 seconds after PL drops, but birdie is 
too strong to squelch at any setting. Dropping PL upon PTT release while 
setting repeater hang time to 1.5 seconds would be ideal. Generating the 
PL on the Pi and increasing the hang time on the Quantar was my plan.

If you have an older radio that doesn’t do tone get you a TS64 board and it will encode and decode for you.
It just goes in the audio chain. They work great!
Here is a link.
