James, For most HF operating, a calibrated K3 is about as "right on" as many commercial broadcast stations (even with the normal TCXO), so I don't think it is a great advantage (unless you are a real purist for frequency accuracy). That is for normal HF operating, but the picture changes when one considers a few of the newer digital modes which are quite demanding about frequency accuracy, and also for those who are VHF/UHF advocates and are doing stuff like moonbounce.
So for many it is "nice to have", but there are a select few who actually need it. 73, Don W3FPR On 4/5/2011 3:11 PM, James Sarte (K2QI) wrote: > Hello group, > > It's been many months since I've posted here, much less actually done > something new with my K3.
