Guest Plug Nickel Posted September 6, 2021 Report Share Posted September 6, 2021 Hello, Recently purchased a TYT TH-9800, purchased a FCC license for GMRS, and was setting up GMRS channels for local repeater access but I ran into a problem / question. This radio will only allow one DCS codec per channel, so how would I have a different TRX / RX codec for the repeaters? Hopefully this is a stupid question. Thanks Quote Link to comment Share on other sites More sharing options...
Guest Plug Nickel Posted September 7, 2021 Report Share Posted September 7, 2021 I guess unless someone can point me to a way to use the RX DCS on this radio, I'll just have to use squelch. Quote Link to comment Share on other sites More sharing options...
mbrun Posted September 7, 2021 Report Share Posted September 7, 2021 I am not a TYT owner. A quick look through the manual I found online leaves me thinking the radio does not support split tones. It appears you have two opens. A common tone for Tx and Rx (or a tone for Tx and none for receive. For DCS specifically, it looks like there are options to invert the DCS on Tx, Rx or both, but again I do not see an option to use independent codes for Tx and Rx.Perhaps an experienced user of your model will jump in to confirm.MichaelWRHS965KE8PLM Quote Link to comment Share on other sites More sharing options...
Guest Plug Nickel Posted September 7, 2021 Report Share Posted September 7, 2021 Thanks Michael, It's a bit of a pain, but I guess if the squelch breaking gets too annoying, I could use the right side of the radio for listening with channels set to use the RX codec and the left side for transmitting with the TX codec.

Did you ever figure this out by chance or did using the right side for rx and left for tx work? I'm looking to do this on mine in the near future for a local repeater myself.

Modesto Posted October 20, 2021 Report Share Posted October 20, 2021 reading the online docs for the 9800 , just program a few channels for this repeater each with whatever tones or codes or offsets you need to have , , this radio can program any frequency split needed with chirp or the hard way by hand .

n4gix Posted October 21, 2021 Report Share Posted October 21, 2021 Those repeaters should be set for WFM not NFM... Quote Link to comment Share on other sites More sharing options...
Guest Wrmg494 Posted February 13, 2023 Report Share Posted February 13, 2023 In the Chirp software, change "Tone" to "Tone Squelch" and it sets the ctcss/dcs for both tx and rx. Quote Link to comment Share on other sites More sharing options...
