[Lowfer] X-Mas Fessenden/Heising Transmission

[Brian, WA1ZMS]

Merv-

Wow, an amazing DX path! That's a new DX record for the Fessenden event. The Heising modulation in the MOPA exciter doesn't go over about 60%. So lots more power in the carrier than a true 100% AM signal. But this would be about as good as any WW1-era voice transmitter would have been.

Will be on for the next 24hrs so let's hope for better copy on your end.

This shows I need to get back on WSJT modes after the holiday and try for a QSO with you.

>> Like in years past, WI2XLQ is now on-air on 486kHz full carrier AM for the annual transmission. Same 5 min audio loop as always. The exciter is the 1921 Heising MOPA and the amp is the SSPA Hafler 9505. 200w carrier out of the amp into the T-antenna. Will be QRV for at least 24 hrs.
