Roberto,

I've done the check. Please excuse me for the delay due 
to the fact that I have 
my stuff spread across two locations 250 Km apart. 
Last week-end I fetched a working 
Rb and brought it here where I have spectrum 
analyzers.

No 70 MHz signal at all, you were right. What I can see is 60 MHz, 
its 120 MHz 
harmonic and then the about 145 MHz from the lamp ignition 
oscillator.

Probably PE1FBO was misled by me, and I, on my hand, had accepted 
the occasional 
70 MHz reading (made with an hand held counter !) being biased 
by the FRS specs.

I apologize.
