[Elecraft] K3 - KDVR

Thu Oct 15 14:19:40 EDT 2009

As an example of use of the K3 DVR, in March I was operating ARRL Phone 
froom P49Y.  When operating split on 40m you have to change your listening 
frequency every so often.  Although I generally use prerecorded messages for 
CQs, in that case it was easy to just record a new message in M1 on the K3 
announcing the updated listening frequency, then send it from the keyboard. 
Having the K3 DVR was very useful in that context.  Also, if you are ever 
having computer audio issues, perhaps due to rf pickup, sending the messages 
directly from the radio does bypass all those problems.  So I think it's a 
good fall-back option.
