Back story:

Maritime Radio Historical Society (MRHS) members have been unable to access the KPH transmit and receive sites due to COVID-19 restrictions. In order to return commercial CW to the air we obtained a Special Temporary Authority (STA) to use a transmit site in Valley Springs, California for station KSM (we were unable to do this for KPH because we don't own that license).

We will send transmissions beginning at 0100Z 4 October on 6474.0 and 8438.3 to test our remote keying arrangement and general operations.

While we are using KSM frequencies the call sign associated with the STA is WRJG440.

If this test works well we may modify the KSM license to permanently show the Valley Springs site as a transmitter location.

Your reports would be greatly appreciated. Remember, please send them to ksm@radiomarine.org

I wish I'd found out about this test before now... Can only be in one place at a time, though. Hope it went well.
