[digitalradio] 7077 Slow Tones
Sorry, but I've looked around and cannot ID the mode I hear on 3577 and 7076, very slow tones, about 1 second each? Any help please ?? Bill k6acj psk31, mfsk, Olivia, etc

[digitalradio] JT65A and ARRL Field Day
After reading though the Bozo guide and the JT65 protocol, I am assuming that everyone is using WSJT as it would be set up for moon bounce or meteor scatter. Has anyone used it sending plain text? The reason I ask, I would like to use this as a demonstration mode for field day and could I stray from the type 1 message and substitute the grid square with the Field day exchange? (4AVA vice FN16?) How would this effect the decoding? Any assistance would be helpful. Thanks and 73's, Jeff, KA1DBE/4

[digitalradio] JT65A Slow decoding
Hello All I'm just getting into decoding some JT65A on 14076 and I seem to have a problem that's probably computer related... but I would appreciate some advice. My clock is sync'ed OK but at the end of a minute (and when I have even seen strong traces) it is 25 seconds into the next minute before decoding finishes. Is this normal? It seems that this would make a QSO difficult... Look foward to your comments. 73 Marc G0AZS PS Computer is AMD 450 MHz 320MB RAM
Re: [digitalradio] JT65A Slow decoding
The computer is very busy in this time frame. Creating a WAV file and other things. If your CPU is slow it will take a while. My dell 500 mhz some times goes to 10 seconds after the minute but never had it run that long.

[digitalradio] ATTN: ALL JT65 HF OPS
All: Please try to spread out when working JT65 on the HF bands. It is impossible to decode signals when they overlap. Remember that the transmit tones are fixed and will not change unless you change your dial frequency. Clicking on signals that are some X-hertz away from zero-beat in the SpecJT waterfall, or the red spike in the WSJT window, will not change your transmit frequency tones. It will only 'zero-in' on the incoming signal. The outgoing tones stay the same. Working JT65 stations this way, without zero-beating, is essentially the same as working split; it's a waste of spectrum and can interfere with other QSO's. One way around this is to use your VFO to dial-in the station you want to work. Pay attention to the DF after you decode the station by clicking the sync tone (red spike) in the main WSJT window. The DF will tell you how far to move your dial frequency to work that station. If your dial frequency reads 14076.0 and a station is decoded with a DF of +300hz, then move your dial frequency to 14076.3 to zero beat. This will put your TX tones near the calling station. It's a good idea to click the TOL to widen it a bit in case your slightly off frequency. Thanks, 73, Tony - KT2Q

Re: [digitalradio] JT65A Slow decoding
Hi Marc With my Compaq Deskpro 731Mhz usually decodes at 6 seconds after the minute with nothing else open.If I have other apps open it could be a long as 10-11 secs. I just double click the callsign and hit auto very quickly and I still make the contacts.

[digitalradio] 10mw QSO JT65
All: Managed to work Justin (N5BO) with 10mw on 20 meters. Justin's report was -23db so it would seem there was some room to go even lower. There's no doubt that you could microwatt with this mode under ideal conditions -- amazing! 04/17 02:27 021900 2 -23 0.08 4 # N5BO KT2Q FN30 OOOTony KT2Q

Hi, Also go to the decode psuedo-button and disble deepsearch options...might miss a weak sign in the deepsearch file but will speed up the decodes... 73 Bill N9DSJ --- In digitalradio@yahoogroups.com, Darrel Smith [EMAIL PROTECTED] wrote: Hi Marc With my Compaq Deskpro 731Mhz usually decodes at 6 seconds after the minute with nothing else open.If I have other apps open it could be a long as 10-11 secs.

Re: [digitalradio] Re: 10mw QSO JT65
Saw that Tonyseems like 2.5 mw would work although with little margin! 73 Bill N9DSJ I think your right Bill. That would have weakend the signal another 6 db. I would guess JT65 could handle that if the band noise was low enough. Need to try that again.
