Elecraft CW Net Announcement

[Kevin Rock]

Good Evening,
     The annual clock change has me working out a new set of numbers for
the net.  Thus tomorrow at 2200z it will be 4 PM here in the Pacific Time
Zone.  The frequencies will remain the same but the propagation seems to
have improved.  Our sun is back to near where it was a year ago happily
ionizing our D, E, and F layers.
     I hope you can join us for a few exchanges.  It has been mentioned
(well actually it was at lunch today with N7NLU) it may be interesting for
a few of you to interact a bit longer after each of the nets is over.  I
agree whole heartedly.  Please use this net as a watering hole and either
use the frequency after we're done or move a bit above and below it to
meet up.  The Thai food was good as was the conversation.  Hopefully we
will all try a bit of hiking together and then maybe a bit of Elecraft
trail operating in the future.

Please join us tomorrow on the Elecraft CW Net held:
Sunday 2200z (Sunday 4pm PDT) 14050 kHz
Monday 0100z (Sunday 7pm PDT)  7045 kHz

Visit our web site: http://ecn.visionseer.com/ for further details.  Thank
you for the web space Dan.

All are welcome on ECN; Elecraft radios are not required.

See you tomorrow,
         Kevin.  KD5ONS (Net Control Operator 5th Class)

Kevin,

By my rough estimate:  2200Z - 8 hours (Pacfic Time Zone difference) =
1400 local time. I believe that is 2 pm ?

I could be wrong, I have always had trouble with globes,
degrees/min/secs, and adding it all up.

Yeah, Kevin moved his clocks in the wrong direction!

... in case anyone else is having a similar problem ....

My new K2 #4438 had both FM-ing and AM-ing on the low end of 80 meters
but only above about 50 watts output..  Above 3700 and on all other
bands it was perfect.  I had mentioned it on the reflector last week
and received several comments and also a note from Ron ZL1TW who had
an almost identical problem.

I found with Gary's help (Elecraft) that the problem originated in the
T-R switch on the PA board.  I won't go into detail here but after a
lot of testing I discovered that a small capacitor (I used 12 pF)
connected from the cathodes of D12 and D14 to ground cured my problem.
Ron ZL1TW tried it and also cured the FM-ing in his K2.

The cause of the problem was probably rf coupling through D14 due to
higher than normal junction capacitance. This resulted in unusually
high dc voltage on the cathodes and Q6, upsetting the action of the
T-R switch during transmit.  This is only a guess ... and I have no
idea why it occurred only on the low end of 80 meters.  All I know is
that my K2, and Ron's K2 as well, are now playing the way they should.
