I forgot to ask - What's with 75-87.5MHz being able to hear TV audio
in the US?

When I visited New York on honeymoon last month, I bought myself a
Sony ICF-35 as a second SW radio. It covered FM down to 75MHz which
was completely new to me. Also I discovered that I could hear TV
stations on this lower band!

Do some TV stations specifically rebroadcast their audio for radio
listeners in this frequency, or is this just a happy side-effect of
still using the VHF band for TV? (All UK terrestrial TV is UHF
nowadays IIRC).

It's a rather lovely feature and a shame we don't do it in the UK.

Dear Mr. Andrew Oakley:

TV Channels 5 and 6 broadcast in the 76-88 MHz band. 75 MHz exactly is an
aircraft beacon frequency and some land mobile is distributed either side of
75 MHz. TV channels 2-4 extend from 54 MHz to 72 MHz. TV channel 1 does
not exist.

The sound channel for a broadcast TV is at the upper end of its 6 MHz
wide allocation. Thus most FM broadcast receivers are able to hear channel
6's audio.

Thanks for the extensive review of how broadcast frequencies are
distributed in UK.

Being a Midwesterner, it is a mystery why one would wish to have a
honeymoon in NYC. Next time, see the real USA.

Mac

Ah! Now it makes sense. Thanks for the details.

Wife's choice, and not a bad one really. NY was sort of like Paris but
much more conservative.

I also spent a week's holiday (vacation) driving through California in
January, sticking to the rural areas and avoiding SF/LA. Drove through
the central valley and headed up through the hills towards Leavitt
Peak which was breathtaking. Was also nice to chat to people who, like
me, were country folk. Mind you, they do like their Christianity
there, don't they?

Dear Mr. Andrew Oakley:
It was a pleasure.
It seems to me that in Japan the FM broadcast band extends down towards
75 MHz.
Please file away in your mind the fact that you have experienced two
atypical areas of the Republic. I have lived in, or visited, many places -
especially in my early days when I was working in radio astronomy. SW was
important during those travels. Consider a vacation to coincide with the
great Dayton, Ohio radio show in the Spring. Drive on into Indiana and see
some of the most productive farms in the world. Take the long drive north
to Michigan's UP with lots to see on the way - a state with as much
coastline as the island of Great Britain. You could return through Canada
on the east side of the lakes.

There are areas where one religion predominates. However, within six
miles of where I live, on an antenna farm well into the country, there is a
Mosque, at least two Synagogues, a couple of temples of Indian religions,
and many, very-different-from-each-other Christian churches.

Come visit the Hartland. Bring a radio. If you have a radio amateur
license, it will be even more fun and interesting. If you do not have a
license, take the very easy exam and get one while at Dayton.

Warm regards, Mac

There are a number of radios that have been built that support FM from
76-108 Mhz, so they will work anywyhere in the world. You have one.

In some parts of the world (like Japan), the FM band is roughly
76-90Mhz. In most of the world, the space between 75 and 88 Mhz is
assigned to VHF television.

VHF channel 5 is 76-82Mhz, and VHF channel 6 is 82-88 Mhz.
