Hi Paul, LF.

A warm coil is no problem, but a failed halyard at the far end is,
especially when a prized porcelean insulator is shattered in the process.
The WX hit again and the RL is on the ground as I discovered this morning but it is not known when it came down so the CW last night probably
ended up in the ground via a tree.

The CW will continue tonight for those interested, but at a reduced output.

Hi Joe,

Sorry about the coil heating difficulties. Is this something new? I
need to investigate my system for heating. I see a small but
consistent change in apparent antenna system resistance during 2
minute WSPR transmissions since I increased power. I suspect this
may be due to core heating in the matching transformer but need to
confirm. It doesn't seem to present any operational difficulty but
is something I want to better understand.

I will welcome a chance to listen for your CW another time. In the
past your QRSS has at times been clearly audible in the headphones.
If you are interested in two way QSOs I would certainly be
interested to try with you. I have a bit of work to do getting my
QSO capability reinstated following some station upgrades over the
summer. I am waiting for a batch of connectors to arrive but this
should be sorted out in a week or so.

73,
Paul

Hi Paul,

Sorry to learn of your foul WX.  We get lots of that up here!
I just came back from the tower. The reflected power jumped
very high so up the hill with a flashlight to check
the downlead, coil etc.  All seemed OK but the coil (2mm copper)
was quite warm! The CW resumed at 0045 and hopefully will
remain on for the night.

There will be another night to try again, Paul.  It's been
quite a while since the last LF CQ QSO from here.

Hi Joe,

I wish I could listen for your CW but I have shut down operations
for the night. We have high winds and power interruptions were
causing reboots of the computer that hosts the SDRs for LF and MF.
My transmit operations are also suspended during the wind storm.

Hi Roelof,

At 2335 the TX mode switch was moved from QRSS100 to 10 WPM CW on
136.5 kHz.  Good luck to you and anyone else who might be listening.

And I am envious of your copy of LT/305!

73 & TNX
Joe
