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 ...

Lower limit for EME

by Earl Shaffer

Hi All. I was searching the internet for information when I ran across this discussion on Moon-net from 2 decades ago. There are a few things about it that might be of interest. 1) Now that we have modern digital modes, certainly that lower limit is even lower. 2) The discussion moved on to a discussion about EME QSB. SM5BSZ has said that he does not experience a significant amount of QSB while OZ1RH concludes that much of the QSB the rest of us experience may be due to tropo. I think this makes sense since as far North as Leif is, he would likely experience little tropo while the rest of us down South of him see it frequently. On the EME logger even among many Xpol stations we observe that one station or another may be locked out from the rest of the world. For me, this happened early Saturday night (ARRL EME) I was nearly locked out for several hours, then later the band seemed to return to normal. The difference seemed to be about 6 to 10db. I attracted little attention to my CQs when I was locked out in spite of my best efforts to TX the correct polarity. Stations that would normally be -12db would be more like -22db then later they became closer to -12db. I must also say that as the evening progressed, neighbors started turning off some of their RFI generators so I saw about a 2db improvement in the noise floor (5 to 6db vs 3 to 4db). At the same time, I was having better luck getting answers to my CQs later. I think a lot of 2 meter EME stations suffer with noise and do not have adaptive polarity RX, so in these multiple hours long QSB fades, I am heard less. This is from the EA6VQ web site. I have not heard him on in a while. https://www.dxmaps.com/discuss/lowerlimit.html I know there are other possibilities for sources of QSB such as Libration, Ionosphere, noise variations and even polarity which gets most of the blame until the station upgrades to Xpol. -- Earl Shaffer, WB9UWA My EME array photos https://www.dropbox.com/sh/bbn2ktonko8e3az/AACHBBOhf6Djk5Pf2c86Br5ja Detailed array photos http://www.gm4jjj.co.uk/WB9UWA/ Facebook http://www.facebook.com/earl.shaffer Linkedin http://www.linkedin.com/pub/earl-shaffer/12/881/735

Help for DC supply of 10 GHz TWT type STC W3MC12D

by IZ2EWV Italian amateur radio station

Hello friends, For my 10 GHz TWT type W3MC12D, manufactured by STC, I’m looking for: the data sheet or instruction manual of the TWT, including the pinout of its connector and the voltage ratings of each pin, and the DC power supply, type PW35A (as indicated in a STC catalogue of the eighties) I know very well that the 2nd item is harder, therefore the 1st one is the most important, for the scopes of checking the correct operation of the power supply or building a power supply… Every help is very appreciated! I wish you a better 2022, full of satisfactions and serenity. Tnx es 73 de Alberto Calderara Via Santa Marta, 26 20871 Vimercate (MB) - Italy IZ2EWV amateur radio station ITU 28 – CQ 15 – WWL JN45qo SKCC #18930 http://www.arimonza.it

Influence of small hardware on the quality of the RX?

by Agustin Bendamio

Influence of small hardware on the quality of the RX? We all worry about improving our equipment, improving the gain of our array, the NF of our preamps ... But I wonder about the importance that other details may have in the quality of our reception, for example our sound card, usb cables, possible usb noise filters, etc.I would like to read your comments and experiences.

IC-705 + LAN Remote Operations + WSJT-X (Wolf Pueschner)

by Christian Barthod

Hi Wolf, Your situation is normal because the VSP cannot be share. I never be able to share it with diferents softwares. If you want to use WSJT-X you have to stop Icom remote Control. An other way is to use Win4Icom software. It can emulate 6 VSP atvthe same Time. Win4Icom is a very good software that I recommand. 73svChristian F8GHE Le jeu. 30 déc. 2021 à 12:02, <moon-net-request(a)mailman.pe1itr.com> a écrit : > Send Moon-net mailing list submissions to > moon-net(a)mailman.pe1itr.com > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.pe1itr.com/mailman/listinfo/moon-net > or, via email, send a message with subject or body 'help' to > moon-net-request(a)mailman.pe1itr.com > > You can reach the person managing the list at > moon-net-owner(a)mailman.pe1itr.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Moon-net digest..." > > > Today's Topics: > > 1.

Re: [Moon-Net] IC-705 + EME + WSJT-X + remote on LAN

by John Regnault

Wolf, When running a remote station the manufacturer's documentation or software is often not what is required! I have only tested an Icom rig once as a remote possibility and rejected it as 'awkward'! I have run Kenwood, Electraft and occasionally Yaesu rigs remotely. My EME station is always remote - there is no way of operating it at the actual station without plugging a client into the LAN! I have found that the only real way to get lots of pieces of different software to work properly is to install a proper Virtual Serial Port software client and use that in preference to 'bespoke' options. I have been using Eterlogic's VPSE for over 10 years on my remote EME station(Win XP, 7 and 10) that can have as many instances of WSJT/WSJT-X as you like (you must disable TX control on all except one) and HRD to give me the frequency to drive the log. Other VSP programmes do work but I have stuck with Eterlogic's VPSE.

More ARRL EME Logs

by Rick R

I was excited to see that we already have 150 submitted logs--still another 150 to go! Please take the time to submit your log, no matter how big or small. If you need help creating a Cabrillo format, I may be able to assist you. There are so many ops that have logging programs that create a Cabrillo log, I hope many of you will share the programs you are using. I know that N1MM logging program and the W3KM GenLog both free downloads, create Cabrillo logs. TNX, Happy New Year, Rick K1DS
