Hello- I have for sale a very nice SSB Electronics dual tube (7289) model #23150 1296 Mhz cavity assembly. This assembly consists of a very nice silver plated brass cavity, an air plenum with a German-made cast alum blower and a bias PC board. Price is 200.00 plus shipping. Thanks, Byron W5FH
Hi Moonnet friends.
I am getting into the process of making plans and calculations.
My mast on the house is strong enough to carry a 2,5 - 3 meter mesh dish,
even during high wind situations.
The azimuth and elevation rotor should be of high standard and good quality.
The reason for this topic.
What about the SPID rotators, especially the RAS HR AZ & EL rotor? Are there
any known issues with it?
Reading the specifications, it should be very accurate and strong.
Are there experiences with that SPID with large dishes on higher bands?
The higher the used band the narrower the beam shape will become.
And, what does the dish users do when high winds are predicted?
Do they put the dish in Zenith position?
I think this will create the lowest "wind aperture" and take lower wind
force? Right?
Looking to the shape, it should behave like a wing and pushing the dish
down. Right?
Many questions, and I have some time to make up my mind.
Now I only need some answers. HI
73, Peter PA2V

Hello- For sale is an excellent condition Down East Microwave 3456-144 (1 watt version) transverter and NOS in box Toshiba UM-2683A amplifier. The transverter is from when DEM was located in Frenchtown, NJ. The transverter is untested and knowing its past history/owner used very little or none at all. Both for 450.00 plus shipping. Thanks, Byron W5FH 281-682-2922. Thank you.
Hi,
I use a Spid RAS/HR AZ & EL rotator with MD-02 controller (from
Rf-hamdesign, Nederland) and PstRotator software.
This combo hardware/software works great. (also good for radio astronomy
sidereal RA/Dec tracking).
My dish is 2.3m diameter with a big heavy septum feed.
Make sure the mast is exactly vertical for good 0.2 degree tracking.
Also important to use the right amount of counterweight on the back side of
the dish.(I use 2x 12kg weights a few feet out). Rotator runs nicely with
only 16Volts with 2.5mm speaker cable (30 feet long).
Note: Use only high quality pair shielded control cable for the encoders
(the shield grounded only at controller side)!
I always park the dish vertically so the wind force is the same from all
directions.

Max-Gain Systems also has a variety of round and square fiberglass
tubing...reasonably priced.

It won?t work with the Flex 5000, or at least I could never figure out how
to do it

Peter,
Looking at the antenna specs:
http://www.m2inc.com/amateur/436cp30-432-440-mhz/
Gain = 15 dBi
F/B = 18-dB
Power rating = 600w
Number of elements = 15 in each polarity
cost = $325.99
Compare with M2 432-12EME
http://www.m2inc.com/amateur/432-12eme-430-436-mhz/
Gain = 16.4 dBi
F/B = 23 dB
Power rating = 1 kW
Number of elements = 12
cost = $178.99
You could feed the Horz and Vert elements
separately and switch to follow Faraday rotation.
If using two 436CP30 the array can handle 1200w
which most likely need with a small eme array.
F/B is less than eme standards so might compromise Receiving (G/T).
If purchasing them new, cost comparison is about
the same as one would need 2x of the 432-12EME for H/V pol.
But my guess one would be better off using all
432-12EME in the same pol and having more array gain (Four = 22 dBi)
But I'm guessing you already have the 436CP30, so
I would try receiving eme with CP coax harness
removed and directly placing a good preamp at
either 15-element yagi (But DO NOT transmit thru
them without T/R relay and separate coax
lines). One yagi will likely only work on JT65B as CW-eme will be very weak.
If I remember correctly (I have not run 432-eme
for since 2010 when I QRV with 100w to my 4.9m
dish with gain of 26 dBi in Hpol) minimum gain for CW-eme is 24 dBi with 600w.
73, Ed - KL7UW
Note: I decided not to QRV 432-eme as I would
need construction of H/V feed, dual LNA and three
relays, and QRO amplifier to be a serious
operator. I QRV 1296 and 50 MHz and working on
3400, in addition to being on 144-eme. That spreads my efforts thin enough.
