HRN 426: Squelch
/What can you say about squelch? This should take about 5 minutes, tops.
What? it’s almost 3 hours? 😱 Well, we do go deep, and we goof around some. But yeah, we even cut some stuff out to just end the show and get to dinner.
Before we dug into Squelch, we talked about this week’s MARS/Amateur Radio Interop activity, scheduled for Monday night through Saturday afternoon. It’s all on 60 meters, channel 1 (5330.5 kHz) with a nightly 10 PM nationwide broadcast (and some check-in stuff), and Noon Local Time ‘net’, Tuesday thru Saturday (so 4 regional ‘nets’. As I type this on Tuesday afternoon, we’ve had one ‘broadcast’ and one ‘net’. I’ll have some video and we’ll talk more on the next episode.
Then, it’s ‘all Squelch, all the time’. You might wish we had squelched ourselves a little earlier, but you do have playback control. Use it!
