If I go into the WSJT...bin folder and issue the command: JT9 -9 -b G -p 10 -f 700 -F 300 \jt9exe\220926_104120.wav the result is this lot. The file specified is a valid, and correctly decoded,

Bob, Thanks for your advice, however exactly where is the frequency tab? I think I have the same WSJT-x. I had one QSO. He had a +22. 73, Evan

Extremely interesting!

Hi Mike I forgot to add, that discrepancies may arise between programs that use a 6 character grid locator to define your home location, and JPL Horizons where you can enter your exact location, due

Hi Frank Are you seeing any evidence of signals on the waterfall? Is your PC time correct? Are the stations you are monitoring using JT65 or Q65? None of the DT values you have seen would be valid

Hi Mike Yes, I think its the difference between geocentric and topocentric calculations. If you look at Moonsked, the 'Range' changes continuously in one direction (today centre of moon is moving

I want to use the command line driven JT9.EXE prog to decode some JT9-Fast signals. While the -Help option shows which tags to include for modes and submodes, I don't see any indication of what to

I had an older version of PSTRotator and they agree much better now with 17.28 -- differing by around 100km as of right now so only 0.026% between them. WSJTX 390620 PSTRotator 390506 MoonCalc

This probably doesn't answer the question but it's pretty interesting! https://en.m.wikipedia.org/wiki/Lunar_distance_(astronomy) -- John P. WA2FZW

I recently looked into this. There is no simple answer. The Apogee and Perigee vary considerably over time. See the following paper from

I have a similar problem, but it usually won't even run 15 minutes. I'm using a 590SG. Starting with version 2.4.0, I had to employ tricks to get band hopping to work. The most successful trick was

They could all be correct depending on the assumptions. Your position on the earth and the distance to the to the moon constantly varies. Examine what each of the three programs assume for the

I don't do EME myself, but several friends do. They are using one of the flavors of Q65. First questions -- what band(s), what power, what antennas? In general, you need a lot of both. The higher you

Hi Mike. I just got this answer: PstRotator v17.28. The displayed Moon distance is now the distance between your location and the Moon surface. It is still a difference around 100km between

Trying to determine accuracy of moon distance. Using WSJTX Astronomy window, PSTRotator and https://www.mooncalc.org All 3 seem to agree pretty well on Az and El but distance is off by about 5000km

I am new to EME and I have been having no results on the decodes. Here is what I get. 2027 -30 4.6 2107 ## 0123456789ABC OOO d*3 2030 -27 -1.5 2056 ## 0123456789ABC OOO

I had a similar issue with FT8 on a Yeasu FTDX-1200, WSJT-X 2.5.4 on Mac OS. I traced the issue to an offset that somehow got set in FT8. This resulted in the wrong frequency being set on the

I'm back. I finally was able to fix soundcard issues. My TS-480 can transmit. Now there is no receiving. Rarely I see aa station transmitting, The Band Activity Receiving is only less than 20 db.
