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!

Gentleman,
I'm just upgrading one of my Elecraft K3 with the new KIO3B board which
is part of the newer K3S. The KIO3B has a sound device on board and I
wonder if anyone in the group has ever tried this sound device running
WSJT off the moon.
It's a rather cheap device based on PCM2901
<<http://www.ti.com/product/PCM2901>>. Specs show that this device has
rather poor frequency response, dynamic range, THD+N, S/N ratio etc.,
just pure consumer stuff.
Does this or will it in any case reduce overall system performance? If
not it will makes things much easier with cabeling, external sound
devices (Focusrite Scarlett), PTT stuff etc. at our upcoming DXpedition
to DU (DX7EME). Less mess, more fun...and less weight, of course.
