Battery Chemistry Discussion

Tolt Dam False Alarm
Wikipedia suggests the altitude of Carnation is 82 feet above sea level. Where, exactly, in Carnation that would be, I have no idea. But if the altitude in town is *generally around 80 feet* then a de

Paint a GP6
If you do it, please sweep it with an analyzer before and after so we can see if it changed the tuning at all. I do know that putting a ladder line j-pole into sched 40 pvc will change the tuning some

Tolt Dam False Alarm
Knowing what the gauges in various locations would generally read is helpful. The depth listed for “Tolt River Road” is 90 feet. Generally the Tolt River Gauge, which is near the end of Tolt River Roa

VARA and Winlink
My understanding, supported by what I’ve seen on the Winlink site, is that ARDOP will be the Winlink supported protocol going forward, with WINMOR being abandoned over time. So ARDOP will not go away.

Motivated by the Weekly Net check-in via Winlink I have been experimenting with Winlink again. In particular I was interested in what changes happen as a result of the abandoning of the Winmor connect

I am happy to let someone else snap the mixer up but I’m super interested in how you have this set up in your shack and what sort of stuff it does for you. I’ve been pining or a way to have multiple m

10m tuneup - total disaster and embarrassing lesson learned
The problem with two tuners is that they’re solving for a tuning solution at the same time, at varying speeds and by adjusting impedances in different ways. In essence, each tuner is expecting a stati

I grit my teeth and use Google Earth Pro. I make it a bearing of 204 degrees and a distance of about 14.8 miles. That’s to a point just a bit east of Duvall, I’m not real clear on exactly where Howard

Winlink W7PFB-10 and W7PFB-11 / Mistakes

I think I’ve got this nailed down. I was wrong about the signal width. On the waterfall it looks to be about as wide as a normal signal. But it is very clearly digital. So. Close examination gives me:
