Major wind gusts, but luckily minimal rain. Several trees down around the
house, but no direct hits. The skys were flashing through out the night as
transformers exploded all around, looked liked we were being bombed. No
power, on generator. The EME antenna, stuck at mid level because of the
pulley failure, survived. The array is askew in both EL and AZ, and wont
know if there is damage to the rotors or the mast and boom just slipped,
but could of been a lot worse. We dodged a bullet. Now to start the clean
up and wait for power again.

Hello all. Announcing my plans for this weekend's ARRL EME contest: As I see there is a major 2 meter CW contest in EU this weekend I will call CQ on 144.152 JT to avoid conflicting with them. Will occasionally tune to 144.040 to 060 for EME signals. Equipment: 4x15 horizontal K1FO's, 4x11 vertical K1FO's, 800 watts JT/KW+ CW, Kenwoood TS-2000X, WA2ODO preamp. Good luck!

Well I do not seem to be having any luck with the Pro-Sis-Tel elevation rotator.
First was the problem with RF getting into the Hall Effect device and screwing up
the settings on the rotator. 'Sort of' fixed, but still needs more work. Pro-Sis-Tel no help at all.
Now I have a second and potentially more worrying problem.
This morning after a few calls of the moon, I managed to burn out an 'N' type connector.
No problem, easy fix, but had to drop the mast down to do it. Again no problem as it is forecast
to go very windy over the next days so the mast would have been coming down anyway.
Got the connector replaced but noticed once again that the antennas were not at zero degree but
pointing up about five degree. Also again the 'H' frame was leaning over to one side by 2 degrees.
I have only very recently got both settings back correctly after a recent gale, then elevation was out by a few degrees, but the 'H' frame was leaning over about 5 degree.
Initially I thought that the 'lean' was due to one of the mounting bolts coming slightly loose. 'Just in case' I had removed it and fitted 'star type' locking washers either side of the bolt so it would get a better grip.
But why has the elevation gone out again ?.
NOW WE HAVE COME TO THE VERY WORRYING FAULT.
I have found that the bracket between the rotator gearbox housing and the 'H' frame has started to split on the welding.
The bracket is in effect a 'U' shape, the two upright parts fixing to the rotator, the bottom going to the antenna 'H' frame.
I can see breaks in the weld approximately 0.5 inch. and can see them flex.
Will have to take the antennas off the rotator and remove the bracket to get it strengthened and re welded.
I really would like to point this out to anyone who has a Pro-Sis-Tel PST-61 Elevation rotator.
If I had not spotted this defect there is a high probability that the next good gale would have broken the bracket.
What chance an 'H' frame and four good antennas surviving a 20 foot fall without damage.

Hi all,
I put on web QRV list for ARRL EME Contest 2012,
you can use it if you want: http://www.darkside.cz/eme.php
By the way I'll not take part of this weekend contest,
because ARRL again set bad date which is parallel
with the biggest European CW contest on 2m
Marconi Memorial contest.. (14-14utc). During this
contest is expected enormous CW activity in segment
144 020 - 144.150 MHz with QROO signals so
any 2m EME in most part of Europe will be
completly dead.. (

Jan, your question reminded me to check my 3cm waveguide switch current
draw in the transmit and receive state.
Apparently my switch handles the pulse automatically as there is no current
flow after it switches states.
Perhaps your switch works that way as well.

Hi,
anyone using Relcomm RDW-RS002 waveguide switch? I found that only pulse
is enough to switch to another position.
I want to try continuous voltage on the pin, but I'm not sure if the coil
survive continuous voltage on pin?
Any suggestion how to make pulse control for WG switch?
thanks in advance,
regards Jan

For the folks on the east coast faced with Sandy, i have good news.If you are using M2 antennas they will survive the storm.I live on the atlantic shore of Nova Scotia about 200 feet from salt water.In 2003 Nova Scotia was hit straight on by hurricane JUAN category 1 with gust to 90MPH.My Delhi tower made in Canada & in 5 feet concrete base survived, my 4X17M2 survived.The only problem was the break in my Tailtwister did not. The problem is the constant torque back & force what i have done since i have locked the mast with a piece of aluminium tubing going through the tower & fastened to the mast with a 1/4'' plate & some UBOLTS.Also I have ropes on my crossboom which is made of 2 sections of Rohn 25 the ropes are bungee ropes tie to metal anchors in the ground.Do not use ordinary ropes they will stretch. bungee ropes will keep the tension on .I know most of you guys know what to do but we have a lot of newcomers & that is for them.

Hello All
At 73 year young my memory sometimes fails me.
My apologies to my friend and mentor Al Ward W5LUA for missing his contribution to the net yesterday.
I failed to comment that he’s active on 24 Ghz and also lent a hand yesterday and always with relaying information from WA8RJF as well as others who I am unable to hear because of my QTH in the central USA.
He is always a great help to the net and we all appreciate his huge contribution to the net and to our fantastic hobby in general over the decades.

Hi EME gang, yesterday evening I worked #92 DXCC on 432 MHz with EI9E. John
was QRV with 4x21el and 400W RF power from 3CX800A7. It was first John´s EME
QSO. If you want to try, his e-mail is johnhearne(a)eircom.net
One moment he was speaker copy. Print screen here
