Portable/back up transceiver

"Mike" nospam @ aol.com demonstrates his rudeness:

I got a really good chuckle out of that one, Jimmy boy. Nice dodge, but I'm
really going to have to send the BS flag up on that one. Both Vertex and
Icom produce amateur radios that are virtually identical in size to their
airband models and some use the exact same batteries. Many models have
multiple power settings depending on how much battery life you want, and
almost all of them produce more power than their airband models.

And they all generate this power when transmitting FM, not AM.

FM is measured by the constant transmitted power. AM is measured
by the carrier power, which is 1/4 of the peak envelope power, but the
device still needs to be able to generate that peak power. Thus, the
FM units produce more power.


Oh yeah, I
almost forgot to mention that many of them are also at least half the price
of the airband models.

Put a stamp on it that says airplane, and get all the governmental
approvals, and it costs more.


I mean, after all, 1w will go "1366.7
statute miles", so it's kind of a head scratcher that the FAA reuses the
same enroute frequencies every 600 miles or so, no? Well, at least for you
maybe.

Perhaps you had not heard that the earth is approximately spherical,
not flat.
