I have discussed this with several fellow hams but have not really got any kind of definitive answer yet. Jimmie. 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. -- Jim Pennino Remove .spam.sux to reply. 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. Jimmie 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 |
