[ARC5] 60m band and SCR274 transmitters

[Christopher Bowne]

Should be easy to do using a frequency counter.  I use a small HP counter and can easily set a command set transmitter frequency to within 10-20 Hz of a desired frequency.  Should be close enough for government work.  They will drift  typically no more than about 100-200 Hz over the course of a QSO.  Frequencies returned by reversebeacon.net are always either right on the nose or within 100 Hz.

 But the way that the rules were explained was that you could only or had to to be legal generate the signal using the USB channel of a SSB or ISB transmitter.  If the FSK signal is generated by feeding AFSK into an SSB transmitter, and receive it with an USB receiver, you will get the same results if you feed the normal AFSK into the USB transmitter or feed the inverted AFSK into the LSB channel.  And absent residual carrier to give it away, no one would be the wiser.  The same is true of CW whether generated the old way or the new way.

Obviously you would in the "illegal" cases have to put the suppressed carrier in the wrong place.

If you swap the tones in the digital modes (inverted) both tones will 
still be above the suppressed carrier for USB. With a plain, good, old 
fashioned CW transmitter just put your signal 1500 Hz above the assigned 
channel frequency. There are numerous ways to accomplish that. Some 
people make it "complicated". As Bob points out..it's simple.

Moving closer to 60 meter operation.
