Earl, Just want to concur with Joe. I have been using Map-65 with an older machine for years, with several other programs running in the background, including Linrad, Trackbox, Eme systems and several browsers. My CPU never goes over 36% utilization with decodes within a few seconds. I am running an old AMD Athlon II, It was a Windows XP machine I have slowly upgraded to Windows 10. Over time I also have switched to an SSD drive and added 8GB of memory. 73 Les W2LPL

Map65?

by Earl Shaffer

Hi All. My Map65 is set up for RX only on the moon with 4 x uwa12 xpol and Map65. I saw I3MEK and F6APE on the waterfall fairly consistently. I am looking right into the sun. My noise level is 6 to 7 db above the level of dummy load at preamp input. I have Dimension 4 running and have verified timing. I see no text at all decoded and was wondering what might be wrong? Mode selected is JT65b. Noise increase at every stage is credible. Still working on PTT and TX audio. I wish I had documented my connections better when I tore down my shack to improve the shack desk. -- 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

ADF5355 synth updated info

by Mr. Sean McHenry

I have been browsing again looking for as much info as I can get on those ADF5355 synthesizer boards and found a nice fairly updated PDF from DD1US. Link below. He mentions the downfalls of the boards as supplied and goes into decent detail on the things he did to make the touch screen version the best it can be. In the article he also mentions that Analog Devices has a drop in replacement for the ADD5355 in the newer ADF5356. It is supposed to have 6db less phase noise. I found it at Mouser but it isn't exactly cheap at $75. That is the only place I looked but for those out there that may have these and be looking for less Phase Noise, their may be the answer so you don't have to scrap what all you have already done with the 5355 version. Also at the end of the article he mentions there is a new chip that may be out now, ADF4371 which covers all the way up to 32 GHz ! Mouser has these also at a heafty $236. https://www.dd1us.de/Downloads/A low cost signal generator 2018-06-09 1v0.pdf FYI, SeanKB8JNE Spell checked by the NSA.

FT857 CAT

by cx2sc.base＠gmail.com

Hello everyone, I am trying to adjust my rig for a first DL0SHF receipt which will then allow me the first 3cm EME QSO. But I always have unforeseen events in my tests !! The last problem that I must overcome is with the FT857D when using CAT for the doppler from WSJTX, the interface is not a problem, nor the configuration, but each data transmission to the FT857 causes a small mute in audio, of only 100 or maybe 150ms, every 1 second. It is surely the frame at 4800bps of data reaching the FT857 .... Does anyone use FT857 with WSJTX with a doppler as aggressive as the 10GHz one? Did you resolve this issue? Thanks for the answers! 73! Ric CX2SC

FW: contraption

by 11061057

Hi guys, I was a bit surprised at the interest my post generated, it proves that the building spirit is not dead. I thank all of you that replied and gave suggestions. The interest generated encouraged me to put together a few pictures of the build and rescue from disaster, to the point where I am today. https://youtu.be/N1YXU0faSOI I hope to be fully operational soon and meet most of you on the moon. Best 73 João CT1FGW

QSL reclaim

by cx2sc.base＠gmail.com

Hello everyone, I have had several QSL claims returned from their senders or in some cases QSLs that are not arriving and are not returned to the senders. Perform a management in my post office and indicate that the UNITED STATES and GERMANY among others, DOES NOT HAVE MAIL CONNECTIONS currently due to the pandemic. I am sorry to receive this news, I recommend starting to make confirmations via Lotw or waiting for the world to normalize !! 73! Ric CX2SC

Equal length coax X-poll antenna group in 2 / wave, 4 / wave or is the same number of cm sufficient?

by Gert-Jan Verheij

hi friends of the moon, I am replacing my broken 12 elements lfa for 144 for 2x YU1CF PA144-XPOL-16-4.5B. My idea is to use a double receiver for RX and to do tx circularly. This is my first experiment with this technology, so I'm still a newbie to this... I understand that the length of both (horizontal and vertical) coax cables to the shack but also between Power Divider and both antennas must be the same. This could be done in several ways: 1. equal length in measured centimeters 2. a multiple of a 2 / wave * velocity ratio coax 3. a multiple of a 4 / wave * velocity ratio coax Which is the best and why? And if option 2 or 3 can I measure this with my mfj259b mode advance> Distance to fault? 73, Gert-Jan PE1GJV
