[Elecraft] PX3 Possible Bug - Refresh Rate Slow Depending on KX3 Digital Mode Selected
Received a PX3 for Christmas. Have been very happy with the unit. However, I noticed what appears to be an inconsistency. What I have observed is that at certain spans (e.g., 2, 5, and 10), the PX3 refresh rate appears to slow down depending on the KX3 digital mode selected (e.g., AFSK A, Data A, PSK D, FSK D). Yet, the PX3 refresh rate is always 80ms when I check for each span/mode combination. PX3 Text display, waterfall, and spectrum scope all enabled with MKR A on. KX3 is set to 14.070Mhz, AGC-F, VOX, FL2. What I mean by slow is of course anecdotal; it is my perception, not measured. At say a span (PX3) of 2 and data mode of PSK D (KX3), the waterfall and spectrum scope appear to be refreshing at a rate I expect based on first impressions with the PX3 out-of-the-box. But, if I change the KX3 data mode to DATA A, the PX3 refresh rate appears to slow down considerably. The same slow down occurs when I change to AFSK A. But, when I move to FSK D or PSK D, the PX3 rate appears to return to a more normal speed. However, this pattern changes when I switch the PX3's span to 5. Now, KX3 PSK D and FSK D data modes seem to have slower PX3 refresh rates than DATA A and AFSK A. Finally, moving the span to 10, I observe the opposite, but not as pronounced; more like the pattern when the span was 2. At a span of 20 and above, I don't notice the difference between the PX3 refresh rates at different KX3 data modes. I have firmware: KX3 - 2.27 / 1.30 PX3 - 1.16 regards, Brian VE3IBW __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] OT K3/KX3 and Raspberry Pi (Irwin Darack)
I built one of those, and it was an interesting learning experience. But its performance doesn't come close to the PX3, which I later acquired. Panadapters tend to be an addictive operating tool. Once I started using the K3-P3 combo I found that operating any rig without one was like flying blind. And having used my P3, the PX3 for my KX3 was hard to resist. But doing the TPP for use with the KX3 was a fun project with just enough frustration to make it interesting :-) The guide done by Josh, M0JMO in the first link below -- and some helpful emails from Josh -- were invaluable to me. Using his parameters I never ran into the freeze problem mentioned in the second link. 73, Phil W7OX On 12/31/14 1:59 AM, Paul20 wrote: You can use the raspberrypi as a nice little panadapter for the KX3, Some reading here http://www.tigerstyle.co.uk/blog/M0JMO-Tiny_Python_Panadapter-Raspberry_Pi_Setup_Guide-v1_2.pdf http://www.aa6e.net/wiki/Tiny_Python_Panadapter#Important:_For_all_Pi_Users_--_Fixing_the_.22Freeze.22_problem Cheers Paul GI4FZD __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] PX3 Possible Bug - Refresh Rate Slow Depending on KX3 Digital Mode Selected
Hi Brian, The slower refresh rate at narrower spans is normal. The reason is that at these narrower spans (below 24 KHz) we effectively down sample the I/Q stream. Down sampling requires the PX3 to acquire many more samples for each screen which directly affects the refresh rate. The sampling rate is tied to the SPAN, and the SPAN setting is stored per MODE. Verify that as you change digital modes, the span stays the same. My guess is that the span set for USB is different than LSB and this becomes the issue as FSK uses USB and PSK uses LSB.

Its is RF hell here, although the dBm values and S-meter scales shown in QtRadio are uncalibrated.
