Re: HUH? New! Satellite Digital Messaging



The 438 to 450 range is probably the range over which the specs are
guaranteed.  The radio transmits without a problem in the range of 430 to
450 MHz.  I wish it would transmit on 420 to 430 as well, but oh well.

Yes, satellite downlinks are below 438 MHz.

I am not sure how much the performance degrades below 438 MHz.  Anyone done
any real studies or testing on it?

Also, I'd expect the news link to be broken as they probably are updating
it.  The (G) model exists (I have it) and it will be available shortly.

73,
