[Elecraft] Fwd: ARRL 10-m contest

[Gerry Hull]

Hey Wayne et al,

I used the K3 and K3/0 mini combo along with the RRC boxes to operate the
ARRL 10m contest remote from K2LE's contest station in Vermont.

Wayne, I was interested in your QSK comments.  I was using QSK on the
remote, and it was working pretty well.

I notice, however, two strange things with QSK, both remote and local...

At any speed, if I engage the RIT or go split, the QSK sounds very
different.
At 40wpm and above, the sidetone is not clean -- it seems to clip.  I know,
however, that the generated CW is just fine.

Is this something that the beta firmware will take care of?

BTW, for those of you who are contemplating CW contesting remotely using
the K3+RemoteRig, you can be rest assured that it performs
flawlessly.  Latency is not an issue.  Here's a snapshot of my rate
analysis for the contest:

The best 60 minute rate was 196/hour from 1249 to 1348
The best 30 minute rate was 220/hour from 1319 to 1348
The best 10 minute rate was 270/hour from 1330 to 1339

The best 1 minute rates were:
 6 QSOs/minute    4 times.
 5 QSOs/minute    9 times.
 4 QSOs/minute   74 times.
 3 QSOs/minute  143 times.
 2 QSOs/minute  172 times.
 1 QSOs/minute  167 times.

So, remote is exactly like being there!  In this operation, K2LE station
end is 1.5Mbps DSL, my end 105Mbps cable.

73.

Hi all,

I only had an hour or so of contest time, but the band was in great shape
and I worked everyone I called in both SSB and CW mode (35 QSOs in 19
states).

Just to make it more challenging, I kept power set to 5.0 watts, and used
my 6-meter antenna exclusively (not a typo--yes, this was on 10 meters).
It's a pair of 6-meter hamsticks forming a dipole, supported by a push-up
mast at about 20'. It's fed with LMR400 coax, then connected to the K3,
which has a KAT3 ATU. The ATU can tune this antenna on 20-6 meters. While
it certainly isn't very efficient on bands below 6 meters, it was good
enough to have some fun in the contest.

I was using the latest K3 firmware (rev. 5.01), which has excellent QSK
audio characteristics as reported by those using this  field-test release.

73,
Wayne
