Re: For more beautiful JUMA(LCD display unit)

I apologize for having confounded you.
I understand that it is difficult to change a kit.
The purpose of this report takes that the individual who purchased a kit
remodels it by oneself into consideration.

Please confirm that a transmission start is not from 0 second.

Re: TX136/500 WSPR modes added

I succeeded in the synchronization with the GPS receiver.
The DT indication in the WPR-2 reception was between -1.2 second and -1.7 second.
I calibrate the PC which I used for WSPR-2 decoding within 200 milliseconds every 30 minutes at the Internet time.

Re: TX136/500 WSPR modes added

I show below some ideas, 1. I want to save beacon messages separately in CW and QRSS/DFCW. In many cases, the number of letters is from only 3 to 6 in the QRSS/DFCW beacon (a call sign or the contracted form). 2. The beacon messages of QRSS/DECW and WSPR want to program it without a PC. Particularly...

Re: TX136/500 WSPR modes added

Hi Patrick,
The test of v1.06b that I used TX136 and TX500 was finished all.
I tried it including CW, QRS, DFCW of the beacon programming.
There were not the new problems.

Re: TX136/500 WSPR modes added

Hi Patrick. I agree to your plan. The issue of modulation in WSPR was already removed in v1.06b. Therefore, I think that it does not have a big problem that TX500 user uses this version. I have the respect for you with big thanks. I will try this version on TX136. And I will continue feedback to you...

Re: TX136/500 WSPR modes added

I tried QRSS and DFCW. It is easy to use it very much and is convenient. I liked in particular QSO mode in QRSS3/DFCW3 that I used JUMA TX136/TX500 Windows control software. http://www.jumaradio.com/juma-tx500/juma-tx136-500-control.html It was v1.06c, but was able to choose RF PWR MAX by this Windo...

Re: TX136/500 WSPR modes added

While I display CONFIG page, buttons of FREQ+, FREQ-, RF PWR and OPER are still effective. Therefore it becomes BEACON mode when I push and hold OPER button for a few seconds, and the transmission is started at effective time. However, the CONFIG page is still displayed and cannot be closed. Is this...

Re: TX136/500 WSPR modes added

I sent much WSPR programming commands including an accident.
Reception data are different from indication of TX500.
