SP Prob & LP Prob

Earl Needham All Messages By This Member #228858 Should I be seeing SP Probability and LP Probability on 6 meters, or is this strictly 10-80 meters? Thanks, Earl / KD5XB Sent with secure email.

Earl Needham All Messages By This Member #228861 Thanks again, Dave. I've been wondering about this for some time, since in the config, on the Prediction panel, both of these bands are included.? It would definitely be a help if either one or both was available. What if I used the ICEPAC LUF & MUF instead?? (I admit, I don't know much about these engines...) Earl Sent with secure email.

W0MU All Messages By This Member #228863 开云体育 There is almost no way to predict (ES) e-skip propagation on 6m and even F2 openings seem to make no sense at times.? Your best bet is to watch dx maps and be in the ON4KST chat if you are a serious 6m op.

(I admit, I don't know much about these engines...) + Older propagation prediction engines may support a wider frequency range, but they are inferior to VOACAP on HF bands. SpotCollector directs PropView to use VOACAP; I'm not planning to enable the use of older inferior propagation engines even if doing so would yield forecasts on 160m and 6m. ? ? ? 73, ? ? ? ? ? ? ?Dave, AA6YQ
Dave w6de All Messages By This Member #228880 开云体育 Just before this was posted yesterday, I managed to work 5H1KB, Tanzania on 10 meters FT8.? As per my usual routine for suspected weak signals I looked at 笔谤辞辫痴颈别飞’蝉 prediction graph.? Not only was 10 meters predicted to be good, the chart had the maximum usable frequency above 6-meters.? I have never heard or worked a 6-meter African station from here on the West Coast.? But it was nice to see the prediction and maybe I’ll work a few 6-meter African QS0s this sun Spot Cycle.. ? 73, Dave, w6de ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Dave AA6YQ via groups.io Sent: 23 April, 2025 21:21 To: [email protected] Subject: Re: [DXLab] SP Prob & LP Prob ? + AA6YQ comments below Should I be seeing SP Probability and LP Probability on 6 meters, or is this strictly 10-80 meters? + "when checked,??1.8.7 or later can be directed to generate Signal-to-Noise Ratio (SNR) and Probability predictions for Spot Database Entries whose frequencies are in the range of 2 Mhz to 30 Mhz." + That range excludes 160m and 6m; it's a limit of the VOACAP propagation prediction engine. ? ? ?73, ? ? ? ? ? ? ?Dave, AA6YQ
