Another small issue, if when transmitting you press a button to send a DTMF or repeater tone, if you release PTT before the other key, squelch gets stuck open and the key's RX based function is executed.

BETA02A seems as though settings aren't saving. Am investigating

The squelch on the Si4732 is based on the chip itself, you either turn it off or on, there's no real settings for it.

I'm testing BETA02, and it looks stable to me. Everything is working fine so far. I'm not sure how the squelch is working for SI4732—is it possible to adjust the squelch, or is it only one setting (which is also fine)? From the RMS, I was also testing all tabs; there are no issues so far—I even saw and tested the scrambler per channel, which is also working fine (please remember about this feature for H3 - if you find time, of course). Thanks, Marcus!

When I switch to SI4732 on SSB, the radio goes silent. RT98

What a king.

The Red LED lights up when GPS is active, this was debug code I forgot to remove. It won't do this in future releases.

Thanks to Marcus for starting work on the GPS; I think it's going to be a challenging step. Since the DTMF function has been perfected, could someone explain how to use it? I'm not very knowledgeable about the subject; I've seen something online, but a more specific guide for the RT-880 and the Nisure firmware is needed. A video tutorial from Marcus would be great!
