hi all,

I'm looking to build a permanent APRS station for my car using tinytrack
, a cheap serial GPS device, and a simple transceiver tuned to
144.800MHz. Finding the two first points on the list is relatively easy,
but finding a suitable radio is more of a challenge.

What is needed is a simple radio which only needs to be tuned to a
specific frequency, 144.800MHz, with audio in and out to connect to the
modem and a fairly commonplace antenna connector. It would need to be a
full transceiver to enable carrier sensing. Price is definitely an issue
and it would be nice if it could run directly on 12V and supplied by the
car battery/alternator. A complete radio is of course the easiest, but a do-it-yourself kit with all the necessary pieces would be equally welcome.

Does anyone know of any suitable radio/kit which would suit my needs?

There are some very cheap transceivers on Ebay - from a source in Hong
Kong - which will give you a couple of Watts of RF on .800 without any difficulty. Just type JT 208 into the Ebay search box.

You'll need a voltage adaptor to drop the 12V car supply to 7.2V for
these tcvrs, but they're readily available in car accessory shops.

Do you know if it is CE approved for use in Europe? I seem to remember something about those radios when sold from Hong Kong.

For licenced radio-amateurs using it on amateur bands frequencies, it
doesn't need to be CE approved. It is just the same as with
equipment you build yourself. That doesn't need to be approved either.

At least, that's how the UK regulations work. Check what it says in
your own licence.

Having just looked at the English language section of your NPT's
web-site, the regulations covering this, seem to be in:

'Section 8-1, second subsection of the Electronic Communications Act.'

Further notes regarding the above Act. show the following as a draft
section to that Act,

Draft Section 6 issues a qualified general authorisation to
possess and use radio equipment. The right to posses, trade
and use radio equipment covered by Directive 1999/5, the
so-called R&TTE Directive, is set out in the Electronic
Communications Act. 5 If the radio equipment is not covered
by the R&TTE Directive, possession, trade and use of the
radio equipment will require an authorisation from the NPT.
6 It is proposed that such general authorisation to possess
and use non-R&TTE radio equipment be issued to parties
holding a radio amateur licence. The conditions for such
authorisation will be that the radio equipment used has a
maximum radiated power outside the frequency bands specified
in the qualified general frequency authorisation of less than 2.5
microwatts in frequency bands above 30 MHz and less then
50 milliwatts in frequency bands below 30 MHz.

This draft was dated 22.04.2004, so should surely have passed into law
by now(?) but no doubt you can check locally or look at your licence.
