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.

G4BAO Dubus 6cm results with new QRP system

by g4bao

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! 73 John

SK6OSO SDR IQ-recordings

by Ingolf, SM6FHZ

Hi all. When posting the IQ-recordings from the GB6GHY operation I had the opportunity to post some IQ-recordings made at the SK6OSO 23cm operation in July 2013. On July 14th 2013, during the SK6OSO 23 cm operation from Onsala Space Observatory 26.5m dish, all stations were asked to transmit via the Moon during two 3 minutes periods and IQ-recordings were made a SK6OSO to communicate how signals sounded from our observing point. The recordings covers from 1296.000 to 1296.080 MHz. These IQ-recordings are now posted at my web-site and can be downloaded and played in SDR-console. The files are about 25 MB each and there is a total of 6 files, three for each listening period. http://2ingandlin.se/IQ_recordings.html We hope you enjoy listening to all the signals present in the recordings including ON0EME. 73 / Ingolf, SM6FHZ -- Ingolf, SM6FHZ http://www.2ingandlin.se/SM6FHZ.htm <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

OT: FS: Relays & Directional Couplers

by Gedas

I have some neat relays & couplers to share and this time I have kept several of each for myself hi-hi. 1. I have some very clean (9.2/10) Anritsu, 12 V, SPDT, SMA, DC-13 GHz relays. The only real wear marks on them are from them hitting each other in the box they were kept in. Just for fun several were swept up to 18 GHz and found the I.L. to max out at about 0.5 dB with a SWR of less than 1.4:1. What makes these relays fascinating to me is the way the contacts can be energized. The connector is a standard 3-pin Molex type. The center pin is common. One side of center will energize one coil, the other side will energize the other coil. Because this relay has two independent coils (one for each port) you can energize one coil, or two, and use the relay as a normal SPDT relay or to make it a "T" connection where all 3 SMA ports are connected to each other. Either AC or DC can be used & the coil draws about 30 mA. They have a very nice 1/8" thick aluminum mounting plate making mounting them a snap. I will start with making 45 available & asking $15 each plus shipping. I just had to take one apart, was neat to see the high quality build & all that gold. http://w8bya.com/index.php/Misc/HAM-1/anritsu-5 http://w8bya.com/index.php/Misc/HAM-1/anritsu-4 http://w8bya.com/index.php/Misc/HAM-1/anritsu-3 http://w8bya.com/index.php/Misc/HAM-1/anritsu-2 http://w8bya.com/index.php/Misc/HAM-1/anritsu-1 http://w8bya.com/index.php/Misc/HAM-1/anritsu-6 2. I have some Radiall, 24-28 VDC, SP6T, SMA, DC-18 GHz rated relays. These relays were installed in some specialized com racks but the racks were never sold and then dismantled so they are very clean (I would call them near pristine 9.7/10). They are rated at 240 watts (ave pwr) up to 3 GHz, and down to 100 Watts (ave pwr) up at 18 GHz, with a port-to-port isolation of 80 dB (down to 60 dB at 18 GHz). The coils draw about 100 mA and each relay contact is rated for up to 5 million cycles. What makes these relays really amazing (other than their awesome specs) are that they have a small PCB mounted to the contacts already ! The PCB uses a standard 20-pin DIP connector to access all of the required contacts and there are 6 LED's that indicate which port is being energized. There is also a protection diode on the PCB. I only have 18 and asking $45 each. http://w8bya.com/index.php/Misc/HAM-1/radial-4 http://w8bya.com/index.php/Misc/HAM-1/radial-5 http://w8bya.com/index.php/Misc/HAM-1/radial-6 http://w8bya.com/index.php/Misc/HAM-1/radial-1 http://w8bya.com/index.php/Misc/HAM-1/radial-3 http://w8bya.com/index.php/Misc/HAM-1/radial-2 http://w8bya.com/index.php/Misc/HAM-1/radial-7 3. I have about 25 used 4-port 1 GHz - 2 GHz directional couplers. I tested several of them and they had around 30 dB directivity, less than 1 dB I.L. and coupling very close to their rated 10dB. They are very clean but do show signs of nicks and little paint chips missing from them hitting each other in the box that held them. Asking $10 each. http://w8bya.com/index.php/Misc/HAM-1/dc-2 Preference given to anyone who wants to purchase an entire lot. Not every one of these items has been tested for specs etc and are being sold as-is. PayPal or personal checks are aok. Thanks !

Re: [Moon-Net] For EU friends, Crimping tool for 10mm cables?

by Ivan Kaitmann

Hi Conrad, you can register by www.shipito.com and establish your US delivery adress there to buy in the US, postage within USA is very often free and Shipito will forward it to you with the delivery method you can choose. I used by eBay several times. 73 Ivan OK1IL ------ Původní zpráva ------ Od: moon-net-request(a)mailman.pe1itr.com Komu: moon-net(a)mailman.pe1itr.com Odesláno: 30.8.2017 21:16:49 Předmět: Moon-net Digest, Vol 329, Issue 8 >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.
