When:
08/13/2022 through
08/14/2022
Where:
All Amateur bands, HF, VHF, & UHF
JS8 Allows free-text like RTTY, etc, so there can be more to a Q besides snr and qth.
Try it out.
For the first time Evar..
I just checked in to Region 10 CW net and passed traffic for Hawaii.
That was cool.

Made an AM Broadcast Band filter.
AM Broadcast Band filter
What temp do you like for soldering in your radios?
Cap and coil in series, tapping the center conductor and out to the shield. Video of it having zero impact on 20M. Lol

not filtering
Need suggestions:
50KW unrestricted AM station tower 6 miles fm qth. Makes a mess on HF. Got a cap and coil to make a trap to shunt 1110KHz to ground and pass the rest to the rig.
Cap: 365pF adjustable
Coil: 220uH toroid.
Put them in parallel. Antenna center conductor to the tank and trxcvr.
Shield to shield on trxcvr.
Output of tank to shield, and later to stati in n ground.
Practically zero difference.
Halp! ; ) Any tips?
