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 ...

Ready on 6cm.

by Bruce Halasz

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. Vy 73 Bruce PY2BS qrv 70cm, 33cm, 23cm, 13cm, 9cm, 6cm and 3cm.

DUAL RX TRANSVERTER & REVEIVER (HA1YA)

by Damien FORESTIER

I stumbled on this site and discovered interresting things. 2m Dual-RX (Special RX converter for 2m adaptive (EME) receiving) http://www.ha1ya.hu/htmkepek/dual_rx.htm ME2-XP 2m dual RX (EME) transverter (The first dual RX color display transverter on the World!) http://www.ha1ya.hu/htmkepek/me2xp_spec.htm Does anyone have feedback from one of these 2 devices? It sounds interesting but I'm looking for someone who has this kind of device to exchange feedback, especially with the use of MAP65 (setup - configuration). 73 - Damien F5RRS

24Ghz SSPA

by Jan Kappert

Hi mooners, For 10Ghz only one preamp is available and we will close further production after delivering more then 100 pcs. We expect a crowed band in the coming time,hi. We are currently preparingthe first batch of a super LNA for 24Ghz with NF: 1.1dB Furthemore we would like feedback for the design and production of an 24Ghz SSPA. Design goal is: 10Watt rf out, Vdc: 15Vd and WG connections.We will design against a reasonable price but need your feedback. Thanks in advance, Jan PAoPLY

Re: [Moon-Net] What's wrong with the IC-7100 as an IF for microwave EME?

by LoWeb＠esp-inc.net

Bob. I would suggest using a Yaseu FT-818 with 5 watts out. They are very stable and have all of the features of a full size radio. The new price is $500 to $550. I've added a 500 Hz bandwidth filter for CW. I use one of these to drive my 10 GHz transverter which has a PLL LO, and this setup doesn't have any apparent drift. There's no power oversgoot either.Ben/K4QFSent from my T-Mobile 4G LTE dev------ Original message------From: Bob Atkins via Moon-net Date: Fri, Feb 28, 2020 23:36To: moon-net(a)mailman.pe1itr.com;Cc: Subject:[Moon-Net] What's wrong with the IC-7100 as an IF for microwave EME? At some point I may need to add a rig to my system as an IF for 1296 (tranverter to 144) and 10Ghz (transverter to 432 or 144). I'm interested in what's wrong with the IC-7100 for EME (specifically as an IF for the microwave bands). All rigs have issues, so what are the "features" that it lacks or "bugs" that it exhibits? Specifically, it appears to be able to tune in 1Hz steps via CAT. Is that correct? Can it change frequency via CAT while in transmit mode? (for use with CFOM doppler for example) What is the "out of the box" frequency stability (Rx and during Tx) and if it's not good, is there a documented/established way to fix it ? Is there an initial power spike when Tx starts and the rig is set to low power (say set to 5w at 144MHz) Any interface issues with WSJT-X? I think the IC-7100 has an internal sound-card and sends audio via USB. I'm not used to this, but presumably it works OK? I'd appreciate comments from anyone using the IC-7100 as a IF for microwave EME. If anyone wonders why the IC-7100, well, right now it's cheap (Under $750 after rebates). The IC-9700 is around $1500, doesn't cover HF/6m and "out of the box" it drifts. I don't need 1296 in the radio. Thanks Bob, KA1GT
