I may be on sporadically earlier than that, using the high power Tx to test for any EMC and compatibility problems so any strong signals on 137.50000 +/- 2.02Hz may be me Yes, the initial programming of teh DDS module is exactly as before, at 19200 baud, the Jason code is tacked onto the end of the DDSPC5 software with a separate serial comms routine for 9600 operation. The only facility I haven't added yet is the ability to programme the Jason increment into the two EEprom location via the serial link - that still has to be done at the PIC programming stage. The new version will have the name DDSPC5J and by the time I distribute it, will have a 'J' command added to programme the increment. If you stick with flash programmed PICs such as the 16C84 and 16C628 then the programmer can be very simple. There are several designs around on the Web. I use the Epic programmer, but looking at the circuit of that it is very similar to many of the homebrew ones.

I presume that the initial programming will be at 19.2kB ?? or have you put the s/w UART down to 9.6 for this purpose?? This means it could be initially programmed manually with a simple terminal program and then Jason started. Are the possible glitches as a terminal program 'lets go' and Jason gains control of the port likely to be a problem?? I will be around most of the weekend and would like a chance to check out my system with Jason now I have found why I couldnt even copy Jim the other week. Make sure you have the Volume Control checked in the Multimedia components of Windows Set-up......this silly Billy didn't. Or I removed it in my attempts to clean up and shift any unnecessary files. I guess we need to get some more programmed PICs for the DDS.....note I must get myself a programmer. Cheers de Alan G3NYK alan.melia@btinternet.com
