GTX LTR "Channels"... Where are the number/frequen

Post by Jonathan KC8RYW »

The GTX stores LTR channels using channel numbers. Where does it store these in the software? I want to hack these lists to a 25 MHz split, for a 33cm LTR system.

Anyone know?

It would be my guess that they aren't stored in the code plug at all, rather in the radio's firmware... Much the same as in an 800MHz trunking radio has the FCC channel number and It's frequency in the firmware.

I was afraid someone would say that.

Not only that, but the channel data on the conventional side is only represented by channel numbers, 1-10 as well.

Too bad that radio model does not allow frequencies to show instead of channel numbers, far simpler in the conventional world when you need a cheat sheet to remember the actual freq. instead of a channel number.

But then again, many 33 CM repeaters out here are under frequency reuse so many of the systems in CA. are the same as in AZ, PLs included, which is pretty cool to not have to reprogram only to change the tones.
