I have one of these in my basement. We use it to heat up tv dinners.

OM: Please see our Web site at radiomarine (dot) org for a full listing of KSM frequencies. Sorry for the odd URL format but YouTube does not allow the posting of full URLs. We look forward to getting your signal reports. VY 73 - RD

been trying to hear the KSM transmissions but don't know the frequencies I happen to be in Washington state and should be able to hear everything even the 500 KHz signals using a 1000 ft longwire which is a half wave around 450 KHzde KD7YUF

Thanks, OM. Sr. Transmitter Engineer Steve Hawes has now replaced all the solid state rectifiers (added by Globe Wireless) with proper mercury vapor types. He had to replace all the filament and bias transformers to do this but it was worth it. Now we have two rows of 4 MV tubes plus two 866s to watch!
