No, it boils down to a technology difference.
Cellphone base stations are really close together in airplane terms. The
inflight telephones use similar technology but on different frequencies
and with the cells much, much farther apart. They do not interoperate.

You can carry it on all you want; you just can't use it in flight
without explicit prior permission from the airline, _NOT_ the captain.
The last time this came up, I posted the relevant parts of 14 CFR 91,
which are general flight regulations applying to all flights inside the
US or on US-registered aircraft.

My understanding is that he has an EE degree. Wouldn't surprise me if
he is a ham as well.

Subject: HW-2036A Harmonics???
I built a Heathkit HW-2036A (2m synthesized rig) about 10 years ago. It's
always worked fine as far as I could tell... However, last week I looked
at its output on a Tek 2710 spectrum analyzer and was dismayed to see that
the 2nd harmonic (around 290 MHz) was only down about 20 db from the
carrier. The higher harmonics were also right up there falling off with
what appeared to be a sin(x)/x shape. I got out the Heathkit manual and
retweaked the final amp, but nothing I did significantly reduced the
harmonics. The specs in the manual say harmonics and spurs are -60dB.
Is this radio broken or are all HW-2036A rigs like this?
The design of the output filter looks somewhat cheesy... That is, the coils
just mount on the circuit board with no real shielding. It looks like high
frequency components would couple right through to the output (which they
apparently do in my radio!).
Has anyone else looked at a HW-2036A on a spectrum analyzer? Any comments
or suggestions appreciated.

Subject: Missouri Radio Center
Does anyone out there in net-land have any experience with Missouri Radio
Center? So far they've given me the lowest quote on an Icom IC-U16 handheld
(commercial UHF - I'm in the public safety business) at $499, whereas most
other places (Ham Radio Outlet, Amateur Electronic Supply, etc) have quoted
about $599 for the same radio. It seems strange that one place has it $100
lower than anywhere else, hence my post.
Thanks in Advance,
Greg

Subject: QSL cards
Two techniques I've come across - one directly, one by repute: -
(a) a ZL replied to a bureau card by returning my card but with a rubber
stamp on the back saying "verified". I wasn't thrilled about this and
I doubt that the DXCC guys would accept that! But I'm not short of ZL
cards, and whenever I send a card via the bureau it's with the expectation
that I'll get no reply, so I can only be pleasantly surprised.
(b) I'm told that the DXCC guys received an application for DXCC, and had an
uneasy feeling about the 100 or so cards submitted. Then they realized
that they were all the same size, and had only a few different print types
represented on them. The applicant had printed them all himself - who
said the art of home-brewing is lost?

Subject: Questions about UK
I am going to be in the UK soon, and am interesting in knowing a few things.
Can someone tell me what the procedure would be for getting a reciprocal
permit? Would I be able to get it from the Consulate in San Francisco, or
would I need to write to Washington? Also, how long would it take?
Also, is there someone who could give me any information about clubs in the
London area?
And, finally; what exactly is the difference between the
Icom IC-4AT (US version) and the IC-4E (European version)?
Thanks.
