[WT-support] CAT frequency read - K3

[Harold Aaron]

Still trying to read radio freq via CAT with no luck.  Goal is to use
ShuttlePRO II for fine tuning in CW/RTTY.

So far all but CAT read of FA works.  Not sure why cannot set curfreq to
result of wtRadio:Send(" FA; ")

Manual test works fine and sets rig frequency, no problem.

--For testing manually set curfreq="14060000" and comment out next line 
curfreq = wtRadio:Send(" FA; ")
catcmd = string.format("FA000%8d;", curfreq)
wtRadio:Send(catcmd)
return -1
