cigarette lighter socket. $20.
16. Two large selsyns, 115V, 60 cycles. One is a Telesyn Type 5HG synchro
generator & other is a Ford Instrument Co. $40 for pair.
17. Transco SP4T 28VDC relay. P/N 14100 w/ N connectors. $65.
18. Transco waveguide latching (transfer) relay. Has 4 ports for WR-75.
28VDC. $125.
19. Microwave Assoc. SPDT waveguide relay, 28VDC. Model 7515-9001?? Has 3
ports for WR-75. $100.
20. Amphenol SPDT relay, 28VDC w/ SMA(f) connectors. $20.

ea 20dB, 3 ea 10dB, 3 ea 6dB & 2 ea 3dB. $5 ea or $50 for all 11
attenuators.
All of the above are OBO & hv bn used in a non-smoking environment & are
presumed to be in working condx. Can only do power up test prior to
shipping. Will guarantee no DOA. When available, prices are based on
averages of sales this year fm eBay (not based on eBay asking prices).
Pickup either in Camp Verde or Chino Valley, AZ is preferred. Except for
the pole & Tri-Ex towers, will ship via FexEx Gnd but need to add actual
shipping & insuranace
costs. PayPal accepted. All proceeds go to Tom's widow. I hv photos of
most equipment which are available upon request.
Tnx for looking & vy 73,

"I was going to use a KX3 with PX3 for this, but have found to my dismay that the level of RF noise from the PX3 makes it useless for weak signal VHF work. "
Today after fiddling around with leads, taking the PX3 case apart and pressing here and there, suddenly I appear to have cured the annoying noise that was masking weak signals from my transverter. I will keep an eye on it, and try and tidy up so that I can get everything in a position where cables etc are in good positions to minimise pickup etc.
Anyway, for now I am much happier that I dont have to go out and find a replacement for the KX3 PX3 combo. I very nearly bought a TS590SG today, fortunately the local emporium did not have one in stock. I had a look at the older TS590S and it did look like a nice radio, the sort of physical size I consider ergonomic with plenty of physical buttons, but not too many. If I was in the market for a solid 100 watt HF radio then it would be top of the list here. The Elecraft K3S also very very nice, but too expensive for my specific needs.
Thank you to everyone who answered my questions about the FDM-DUO and the 590SG and also who did checks on their own KX3 PX3 rigs.
Looking forward to setting up the KX3 with transverter for transmit soon and perhaps working some of you on tropo or meteor scatter. EME a little later once I get an antenna system for that.

Hi All,
If anyone still need ON on 70cm EME . ..
I will be QRV on 29May from around 1730 to ??? around 432082
Or If anyone need a sked no problem at all
I am open to suggestions
Setup 432Mhz

I have just acquired an LNA technology CA144T 2m LNA. I cannot find out
much about it, I was going to use in on my 2m terrestrial system as it
is a more convenient than size the other cavity input LNA that I have.
I looked on the LNA technology site but they same to have shut down
amateur operations apart from a power meter add on.
Any info? Device? NF? Gain?

I have for sale a antenna works 8877 amp with power supply and spare tube
Asking 2000 or best offerContact N6rmj PatN6rmj(a)sbcglobal.net
Sent from my Verizon 4G LTE Smartphone
Wanted: KD6OZH article on low noise PLL from QEX, etc
I need to have a look at (KD6OZH, Sk) John's Phase Locked oscillator
designs for possible use in my EME projects.
Thanks!

I have a 14MHz to 144MHz transverter and am looking for anyone who has tried the Elad FDM-DUO transceiver as a tuneable IF.
I was going to use a KX3 with PX3 for this, but have found to my dismay that the level of RF noise from the PX3 makes it useless for weak signal VHF work. There is also a huge birdie radiated from the KX3 around 144.4MHz.
Having taken great care to make sure that electronic appliances around my house do not cause noise on the 144 MHz band, it is so disheartening to find that the transceiver and panadaptor themselves cause such interference.
The Elad transceiver looks interesting since it can be locked to 10MHz and has low power output for transverting. It would however need a computer for displaying the bandscope.
This rig would be mainly used for 144MHz terrestrial work, as I plan to use an HB9DRI dual polarity system for EME if I get XPOL antennas installed again.
So, as I can't try before I buy and don't want to make an expensive mistake again, has anyone used the Elad on 144, if so I would like to hear all about it.
Many thanks,
