2023年9月24日 · This video covers the basics on generating and reading the VOACAP charts provided on the W8S website. I briefly explain the REL, MUFday, and SDBW and show how to use them to help predict the best time to try a contact.

2023年6月17日 · PowerSDR KE9NS v2.8.0 has 5 different live maps (and 1 traditional map) available: Move your mouse over the "Maps" button (top line of the PowerSDR console screen) LEFT CLICK: Spotter Tracking World Map with Grayline, Sun-Moon Tracking, ISS, live DX Spots, VOACAP prediction contours. WHEEL CLICK: Opens separate Callsign prefix Map window

2021年6月22日 · This is the source that HAMQSL.com gets the MUF data for the solar banners, and the reason they have shown No Report since 15 Jun 2021. From the University of Massachusetts Lowell: As of 20 Jun the issue has been identified and a fix is being implemented.

2013年9月17日 · I am sure most of you have noticed Boulder MUF on the QRZ homepage app has been reporting No Report for some time. Actually it's been down since mid 12 Sep 2013. I have contacted NOAA in Boulder and they believe it is a result of the floods (communications problems). They have indicated that it will be back online as soon as practical.

2021年6月23日 · The explanation of N0NBH's space wx chart starts @ 38:00 and is fun.. MUF out of Boulder "No Rpt" = no report.. Regarding the 6/4/2m Band section- "Closed". As Dr. Skov mentioned, this is a broad generalization. It's a good idea to look up the current MUF (D/E/F prop), Hepburn tropo maps, and Sporadic E condx (roughly 24MHz+) for your region.

2022年12月26日 · RADAR is "range..." . That means that if the MUF is below 9.6 MHz, the target may be a reasonable reflector. There is a delay between the transmit signal and the receive signal. Go look at the predicted delay between the end of transmission and the beginning of the suspected bounce on RX. HAARP is --inviting--you to participate.

2025年1月2日 · How about an AI extension that runs my radio 24/7, calling CQ, and answering CQs, automatically jumping around bands depending on the MUF, recognizing friendly gesture, answering with friendly gestures, logging contacts, automatically uploading to LOTW, aiming for DXCC? And all the other achievements? Sort of a WSPR on steroids.

2025年2月11日 · JS8Spotter for JS8CALL is a useful companion program that tracks activity on JS8CALL as well as plots users grid squares on an offline map. It also allows users to send forms very efficiently over this slow but robust weak signal mode.
