I have discussed this with several fellow hams but have not really got
any kind of definitive answer yet.

As a licensed amateur (I'm assuming US), you can do anything you want
with your equipment as long as you don't transmit outside of the
frequencies and modes authorized by your class of license.

Thanks Tom and Jim, It was also my reasoning that if I could build my

own transmitter and operate it surely modifying equipment would be
legal as long as I did not transmit outside the bands. The radio is
an Icom and I use software thst I wrote to control the frequency/mode.
It would not be too difficult to modify the software to limit the
frequency data sent to the transceiver in accordance with the band I
am using. The software already "knows" when I use the transverters so
I get the proper frequency dispaly. As the XYL and YL may be using it
some goof proofing may be in order. Hopefully soon I will also have
the computer controling the switching of the transverters.

The spectral purity specifications in part 97. Most HF rigs have allowed
some out of band operation ever since I could remember. It is the shared
responsibility of the station licensee and control ops to stay cleanly
within their grant. Regular RG 58c provides at least 60db of isolation
from
adjacent cabling. Be aware of the possibilities of what might come out of
the antenna ports and take appropriate action. If you waste a little power
in an attenuator and/ or filter circuit on the input of the Xverter,
spurious from the driving radio are also reduced. Nice to be able to
verify
with a spectrum analyzer too if you know someone. GL- Hide quoted text -

I did the mod today and it certainly is nice to be able to work the
whole 2M band AM/FM/SSB and CW. I still have to do some cabling when I
go from HF to VHF or vice versa I have some really good coaxial relays
that I could soon rig up to operate manually and hopefully controled
by the PC in the more distant future. The transverter I have was set
up for use with a 10M IF however if I could modify it for a 6M IF
things would be greatly simplified as the transceiver covers 6M at
reduce power(10 watts) compared to 100 watts on HF.

I certainly like the idea of using the ham rig as a decent general coverage
receiver for SWL and I had to do the mod anyway for 60m operation. You just
have to get in the habit of looking at the radio to verify conditions before
keying up. Like checking the swimming pool to see if there is water in it
first.
