I am planning to be QRV on 3cm for the next 3 days from 10:00z.
System is 1.8M PF dish, 20W at feed and Vertical polarity.
It would be great to test out the system some more.

We are considering to run a pilotbatch of 10pcs preamps for 6cm band, CLNA.
sma connectors for in and output
Nf: 0.5dB (35K)
Please drop me note if you are interested.
Production / delivery will be around April
For 10Ghz we will plan another batch of 10 pcs as well.
For 24Ghz we do not accept new inquiries at the moment. The planned new batch is already full booked.
PS: we have some stock for adapters: WR42-sma and WR90-WR75.
Hello friends 28.01.2023-29.01.2023 ssb fun contest will take place. I plan to participate. Let me know who will participate. what ranges? 23 or 13cm? And where should I send the report?

I have downsized my 2 meter station eliminating split receive and transmit
feeds along with dual channel SDR's so I have a bunch of pieces that
supported that for sale.
The relays are all 26.5 to 28 VDC. Why that voltage you may ask. Well those
relays are generally cheap at swaps and it was much easier to build a 28
volt DC supply than pay the premium for scarce 12 volt relays. My station
runs a KW and I've never had a problem with any of the relays most of which
are Dow Key.
Here is the list:
2 Dow Key 49-104 all N connectors with external contacts
2 Dow Key 60 -2301 all N connectors with external contacts (one needs
adjusting) $25 each
3 Dow Key DK-77 low power relays all BNC connectors $15
2 Ameco/Collins relays N connectors except for receive side which is BNC
and was used for preamp isolation $20 each
3 ARR P144VDG 2 meter gasfet preamps 24 dB gain $55
3 ARR P30-1000 MHz 11 dB gain preamps used to boost signal to the IQ+ SDR.
2 Mini-Circuits 3 dB hybrid splitters 10-1000 MHz $20 each
Shipping is extra. Offers considered for everything in bulk.

Any use ? ( or others from this company?)

Subject: [UKMicrowaves] Mil round connectors
Fianlly, after more than a year, I found time to go and collect the dish and mount I purchased ... it looks to be a heavily built thing, with a feed in WG15 ... opinions are somewhat divided as to whether that will work on 10G, but anyway ...
Connectors however are an issue, I got no cabling with this thing and I really can't afford to blow the entire budget on buying them from RS ... I need a couple of the servo connectors, these are a 14-12 cable female, 4 big pins, 8 smaller pins in a 14 sized shell. Looks like:
I need 2 19 pin cable females, 14 size shell ...
The RS prices is stupid, there are some in the USA on eBay that are more affordable, but before I resort to that I wonder if anyone has any lying around in their "unusual mil spec round connectors" box?
Happy to pay £10 a connector.
Just FYI this driven by two-phase AC servos and has resolver feedback. I plan to use a Mesa 5i23 CNC control card, with the 7i49 6 channel resolver card for control, and probably some home-brew DSP for the 2 phase servo signal generation, feeding a 4 channel Class D audio amplifer to provide the actual drive to the servos, and a bit of Python script to calculate the moon position and send motion control commands to the controller. What could possibly go wrong?
