Problem: Connect+QSY is very slow, especially with poor radio conditions.
Connect should be streamlined to bare minimum:
1. No signal reports before QSY etc. No extra chatter. Delay or suppress welcome messages if the connection is poor/slow.
Connect should specify the QSY channel up front (similar to CW)! Ideally an empty channel should be located and negotiated automatically if possible.
Also, you could make frequency change more efficient by channelizing it and specifying a channel number. Or at least abbreviating the frequency (e.g. 14105750 - no need for 0 padding in the protocol)!
Already submitted by many. on the TO-DO list already. no pre-QSY freq tough. too much work for a link not sure to be estabished. but minimal comm upon link establishment will be implemened.
