Re: TX136/500 v1.13 WSJT-X compatibility + a little effort

HI Patrick, There is a difference between manual TX start and automatic TX start such as: 1)Manual start is triggered by GPS time, 2)Automatic start is triggered by waiting time counter. GPS time shows actual time if a pulse dropped. But waiting counter counts down by IRG * 1000ms independent of dro...

Re: TX136/500 v1.13 WSJT-X compatibility + a little effort

HI Patrick, Thank you for your reply.  I am testing of dropping pulse of GPS now. GPS is located near windows. JUMA TX500 shows "T^mm.ss". When good working, 160 slots are finished 110s after auto starting of FST4W-120. But bad condition, transmit finish 120s after auto starting. At this p...

Re: TX136/500 v1.13 WSJT-X compatibility + a little effort

There may be an essential problem in automatic start transmission of FST4W-120 mode. Usually, Automatic start transmission shall be begun at every 1 second of even minutes in UTC. But TX136/500 v1.13 start at 02s, 03s in GPS time. This causes differential time delay as 1s , 2s at the receiving side....

Re: TX136/500 v1.13 WSJT-X compatibility + a little effort

F5GCB and the other TX136/500 users HI I am success to install TX136/500 v1.13 on my TX500 today. I feel that both MPLAB and program device were updated for 7 years so far. Now FST4W-120 works very well with a 12V battery, GPS and additional LPF. Thank you so much. I will use only FST4W mode as WSPR...

Re: TX136/500 v1.13 WSJT-X compatibility + a little effort

Patrick, Thank for your providing of v1.13 and v1.13j. There is a formal regulation equal or less than 50W for portable amateur radio equipment in Japan. However, many amateurs use TX136/500 under 12V with re-chargeable battery. I would like to try for re-chargeable battery in v1.13 or v1.13j. Now I...

I wrote a decode test program for Opera, but not implement of FEC at this time.
This may help for better understanding of OPERA.

Re: TX136/500 v1.07 OPERA and JASON modes added

I wrote a short testing program on Opera decoding: manchester decoding and de-interleaving program.
As far as my test, the start bit shall be one bit as Patrick's program and Jose's opera_generator.

Re: TX136/500 v1.07 OPERA and JASON modes added

Hi Patrick,
I find that switches of my TX-500 generates multiple noize, say chattering, so sometimes skips a character atter push freq+- button.
Now I am managing my TX500 with V1.07J.
Thank you.

Re: TX136/500 v1.07 OPERA and JASON modes added

Hi Patrick, I feel a small difficulty to add a space in QRSS/DFCW/JASON message using beacon configulation mode. I think a default letter for new position should be a space code(20h) instead of a number zero character(30h). By the way, I can change the beacon message including a space through ETA-23...
