I have been playing with a new Triquint ULNA device (TQP3M9036). It
Shows a lot of promise. It is like a MAR or MSA device in that it is
50ohm in and out. and has a claimed NF about .4db nf ( their numbers).
I have built several pramps to test them and have gotten even better
than they claim and they cover 50-1296 with ease and NF is .4ish or
below. The S11 and S22 are both great and the OIP3 is +35db also
...very nice device. It has great promise as a good terrestrial LNA.
Preamps are foolproof to build and would cost under $50 if all the best
quality parts are used.
Just for information only ...

Hi all,
I’m ready on 6cm with the same dish I’m using on 3cm.
Despite the strong local 5 GHz WiFi noise, had a nice 579/569 first QSO with this setup today with HB9Q, thank you Dan !
Setup is a 3.7m dish and 60W at CP feeder.
I can be QRV on 6cm or 3cm most of the days, skeds and tests are very welcome, as usual.

qrv 70cm, 33cm, 23cm, 13cm, 9cm, 6cm and 3cm.
This weekend I operated 6cm using just 16 Watts to a 1.9m PF dish with an
SM6FHZ septum feed (kindly loaned to me by G3LTF) On RX, a single stage
0.9dB LNA based on a "Franco" LNB board. See RSGB RadCom "GHz Bands" column
July 2014 for details.
I had 7.5dB sun noise and 0,25dB Moon noise.
On CW I worked OK1KIR, HB9Q and DF3RU. "Gotaways" on CW were OK1CA, OF2DG,
ES5PC, PY2BS all identified calling CQ. I need more power!
On JT4F I worked HB9Q, OK1KIR, OK1CA UA3PTW, OZ1LPR and PY2BS.
A good start to the 6cm project at G4BAO. Watch this space, more power
planned!

Hi All.
Just wondering when there will be some activity on 13cm ?
I am on HB9Q logger (13-9cm) every day but not much people around there.
Every month there are separate band contests at the best propagation
weekends,
In between most switch to the next band and have no time to try other bands
Except for a few that I managed to work and on my request put the correct
feed in there system.
If activity is only at 13cm contest weekends then this was sure a waste of
money,
Lucky I had the fun to assemble all parts and have it all working.

make the first 3cm EME QSO between two SA stations.
Congratulations Bruce PY2BS

Befefore I reinvent the wheel this spring and before I strip down my RAS,
has anyone out there fitted absolute rotary encoders of the MAB 25 style to
a SPID RAS and more importantly documented it?
Also if anyone has stripped down and rebuilt a RAS I'd be interested in any
tips, pitfalls and gotchas.
I used to regularly strip down and rebuild a a Suzuki T500 charger engine
in my youth,so I'm not scared to have a go but I had a Haynes manual!
You could save me a lot of time and headscratching.
Also an exploded diagram of the rotator would be nice
Answers on a postcard to.......

Would anyone have a gently used 9cm transverter you would consider selling? DEMI, DB6NT or ? Prefer one with L.O. that's set up for 3400 eme & 10Mhz ref but i will consider all.
Please respond by direct email.
