[AMRadio] New FCC rule

[Donald Chester]

If that is strictly interpreted, wouldn't it also make it illegal to modify an AM broadcast transmitter and use it on the ham bands?  Or even a military surplus transmitter like an ARC-5 or T-368, since they would still be capable of operating outside the ham bands?  Most older ham rigs like the DX-100 and Viking series are capable of transmitting quite a way beyond the band edges.  The Viking II CD edition is capable of covering nearly the entire HF spectrum.

What is the line of distinction between modifying a commercial radio for the ham band, and using the parts from it to build a homebrew rig?

I'd say once you modify a part xxx transmitter for the ham bands it automatically loses its certification, therefore it no longer has any certification of any kind.  Since hams are exempt from certification of their transmitters, they would be free to use it on the ham bands.  But it would be illegal to go back and use it for the original service it was manufactured for, since it is no longer certified for that service.

It sounds like she is saying that if you build a homebrew transmitter, you have to make sure it is incapable of transmitting even 1 kc/s beyond the band edge. If the FCC were to strictly interpret this, it would be a slippery slope towards mandatory type acceptance/certification of all amateur equipment, making it illegal to build one's own transmitter.  Canada, UK and Australia already have such a rule for their foundation (entry level) licence class.

This means you can't modify a CB for 10m, and use it, anymore.

How many commercial radios have been modified for repeater use?

Stupid, Stupid, Stupid.
