ROB SHERWOOD TEST: ICOM IC-7300

Here are the test files from Rob Sherwood.

BONUS:  In December of 2016, Rob used the TS-7300 in the ARRL 160m CW Contest  and was quite pleased with its On-The-Air performance.
His review of the IC-7300 under contest conditions is below the downloads.

USING THE ICOM IC-7300 IN THE ARRL 160m CW CONTEST

I really enjoyed using the IC-7300 during this weekend’s ARRL 160-meter CW contest.  320 Qs, 55K points, a little under last year’s 63K points (all search and pounce).  No fault of the radio. 

I have zero complaints about using it in a CW contest.   While I wish the Bandscope / waterfall display had more options, the Bandscope did the job very well.  It needs an option to make it taller vertically in some mode and leave out the waterfall.  It could also use a 5 dB / division scaling since few stations ever go near full scale.

I hope Icom fixes the transmitter’s “key-up tail” one of these days, but my Alpha 89 or Acom 1000 won’t un-key until all RF is gone so they have no problem with this, but that isn’t the way to solve the problem.  Users may have problems with other types of amplifiers that don’t have this feature.
