On
offer is a home constructed wide range FET Dip meter, complete its coils, that
dates from a 1985 Practical Wireless design.
The
dip meter measures about 2.50 inches x 3.00 inches x
5.00 inches [excluding the control knobs and coils] and is powered by a PP3 9v
battery. There is a six range coils, which are;
1.8MHz -
5MHz
4MHz -
11MHz
8MHz -
22MHz
16MHz -
44MHz
32MHz -
100MHz
60MHz -
150MHz
and a
variable tuning control with the tuning coverage scales is shown, and can be
seen, in photograph 5. A copy of the construction article is included in the
offer which came from the October 1985 edition of Practical Wireless.
This
was amongst the contents of the workshop of an engineer and 'silent key' radio
amateur, who had been involved in many aspects of amateur, military and
professional wireless over many years. I do not have the time or facilities to
test it, so it is being offered as 'sold as seen’ with the eBay listing as 'For
parts or not working', without guarantee or returns, in order to comply
with eBay’s terms and conditions.
However.....A new battery was fitted to the dip meter and it was placed near [not
connected] to the telescopic aerial of a working FM transistor radio switched
on and tuned to Radio Solent [96.1MHz]. As the GDO was tuned through 90MHz -
100MHz it muted the received broadcast station, indicating that the GDO is, at
least, working on that range.
Buyers
please note that there is NO battery included in the offer.
In
the event of the dip meter not working properly, it should be easily repaired,
as these are constructed using all discrete components. It could also be used
as a donor for a faulty or damaged similar instrument or re-purposed for
another project.
This
dip meter will appeal to engineers, home constructors, experimenters and
collectors of vintage test equipment, and would enhance the benches of period
style or modern workshop settings.
It
looks very clean, and the condition and description can better be judged from
the photographs, which are of the actual FET dip meter and coils on offer for
sale.
This
has been priced to sell, without reserve.
