Regrettably, with a lot of rigs, this is an easy task, since a lot of amateur rigs are based on commercial equipment. It is easier to add a diode here and there than design a whole motherboard for each model.
So many folks use modified amateur rigs for other services, when in the USA you cannot do without a specific FCC type acceptance.
Even on the ham bands, you cannot use a commercially manufactured rig that hasn’t had Part 15 approval for the receive stages… something of high debate…
That should sort your problem out.
It seems to be that anyone asking for a way to mod a rig, is the object of shock and horror!
Not everyone lives in the US, and restrictions are not as rigorous in other countries when it comes to playing with rigs (as the VE4 station pointed out).
This is a help, discussion forum, and I’m sure that many users are aware of their own legal ramifications if they do something that they shouldn’t with their rig.
My motto is, “If you have nothing useful to say - Say nothin’”
Sorry for being so outspoken, being a newbie an’ all, but I just like to give my opinion where I believe it may help.
Have a good one!
Well PPH, the OP specifically mentions the fact that radios are made to not interfere with public safety frequencies, which he is right. Obviously Australia has some sort of laws regarding this as well as the US. Which is why I stated what I did.
I have a motto too. “If you feel you are right, state your opinion, even if it might be unpopular.”
