Hi,
I am on the latest firmware, 2.76. Recently I have played around more with
AM listening on the SWL bands and generally found it enjoyable (audio
clearly there from 100-4200Hz when set to do so!!). However there is
definitely an anomaly with the VFO tuning rate (steps per revolution VFO
CTS).
The USB X-keys Jog Shuttle Pro with the knob looks to be one of the more
interesting offerings. Has about enough keys and a knob to tune the radio.
Might work real well with HRD. Got to save the pocket change for a while
before I can order one.
