[Hallicrafters] 5 MHZ

[Bob Wilder]

 From the ARRL web site, here is what the rules say about 5MHz operation:

An amateur station having an operator holding a General, Advanced or Amateur Extra Class license may only transmit single sideband, suppressed-carrier (emission type 2K8J3E) upper sideband on the channels 5332 kHz, 5348 kHz, 5358 kHz, 5373 kHz and 5405 kHz. Amateur operators shall ensure that their transmission occupies only the 2.8 kHz centered around each of these frequencies. 

The key here is the J3E emission with a maximum of 2800 hertz audio.
