Sunspot Cycle 25 could have a magnitude that rivals the top few since records began
by Bob Bascom 21 Nov '20

21 Nov '20

Here's some good news: A research paper https://arxiv.org/pdf/2006.15263.pdf , "Overlapping Magnetic Activity Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude," by Scott W. McIntosh, Deputy Director of the National Center for Atmospheric Research in Boulder, et al., has concluded that Solar Cycle 25 could be among the strongest sunspot cycles ever observed, and will almost certainly be stronger than the just-ended Solar Cycle 24 (sunspot … [View More]

Power Supply
by Nick Shearer 13 Nov '20

Hey there, wanted to see if anyone has an old Power Supply I could purchase from them. Trying to program a mobile but would love to do it off my home computer instead of a laptop and in the vehicle. Thanks ahead of time!

Hi Dave - I currently have multiple Yaesu VHF/UHF radios in-use & “have had” others over the past years; I've never had a noise issue as described with any. This said, I’ve never had a FTM-7250DR.

Dual band Yaesu mobile users - does this sound normal?
by Dave Schmidt 06 Nov '20

06 Nov '20

Question for the group - I have a new Yaesu FTM-7250DR dual band mobile rig and I'm questioning whether what I'm about to describe is normal for a Yaesu. The squelch level required to turn off the audio is very high but only on VHF freqs. Range is 0-15 and I need to set it to 9 for VHF freqs and only 1 for UHF. This is very different than my Kenwood TM-281A, and my Anytone 77UV, both of which squelch level 1 is sufficient. This is with the same antenna (Tram 1480 base antenna), coax (LMR400) … [View More]
