G’day
I’ve enjoyed the recent discussions about the best cost-effective transceiver
for use on 160m. Thought there were a couple of other ideas to throw into the
pot on this topic.
For those on a serious budget, the Icom IC-751A and the Kenwood TS-830S are
still excellent performers on 160m for $500 or less – and can be found with
500Hz filters in two IFs if you are lucky. The IC-751A is also a great
receiver for the 630m band and DX listening to NDBs.
For those topbanders like Barry N1EU who are interested in SDR, the latest
version of the PowerSDR/OpenHPSDR software and its associated firmware places
the coding involved with CW generation inside the main FPGA associated with the
HPSDR/Hermes/ANAN radio. The radio’s sidetone is generated completely in the
FPGA and is not sent to PowerSDR, so there should be zero latency between a key
press and the radio’s sidetone appearing.
I haven’t tried this software on my HPSDR yet, but am looking forward to doing
so, as this improvement apparently removes the last hurdle for a SDR
transceiver to be a truly attractive alternative to the K3 etc for a serious CW
DX/contest operator.
