[Elecraft] P3 and Digital Mode Operation
I've been testing the P3 URL:http://www.elecraft.com/news.htm for a while now, and it has a really nice feature for Digital Modes that my other panadapter solutions lack. The P3 has a SPAN control.

Re: [Elecraft] P3 and Digital Mode Operation
Lyle, am I correct in my understanding that the P3 does not require any connection to a personal computer for any reason? If it does rely on an external PC for anything, will software be available for all platforms (as with the K3 utility) or only for Windows? Those of us who use Macs obviously have an interest in this question. 73 Lew K6LMP On Mar 29, 2010, at 11:40 AM, Lyle Johnson wrote: I've been testing the P3 URL:http://www.elecraft.com/news.htm for a while now, and it has a really nice feature for Digital Modes that my other panadapter solutions lack.

Re: [Elecraft] P3 and Digital Mode Operation
Lyle, am I correct in my understanding that the P3 does not require any connection to a personal computer for any reason? Firmware updates are via RS232, using P3 Utility. For normal operation, the P3 does not require a computer to be attached. In general, think of the P3 as bing invisible to the computer, so your logging programs, etc., will continue to interact with the K3, or not, as you wish. 73, Lyle KK7P __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] P3 and Digital Mode Operation
Good idea, I'll add it to the list of possible future features. I haven't used MTTY, but I assume the X-Y display is like the plus sign on the old analog RTTY demodulators of years ago.

Re: [Elecraft] P3 and Digital Mode Operation
You sure know how to hurt a guys feelings, Alan, I plan to use an old analog RTTY demodulator, the HAL ST-8000 with my K3 :^) !!! I, too, would welcome a good X/Y tuning feature on the P3.

Re: [Elecraft] P3 and Digital Mode Operation
The absence of an XY scope for RTTY was an irritant when I had an FT-2000 and DMU, so it would be a nice addition in the P3. I don't remember seeing this mentioned, but will anything be displayed on the P3 during transmit? I've had two SB-610 scopes and one of the last ones, the HO-5???, but don’t have any scope now to monitor my transmitted signal.
