Hi Alan
Thanks for the link. It is a very neat and versatile device
indeed. I did a look and did not find an equivalent model for the
SPM 16 and 19 units, only a return loss bridge for 75 Ohm
impedance. These run about $350. There are a couple of RFZ-12
units available, but the price tag is well over $1,000. I will keep
my eyes open for one at a more reasonable price.
Thanks
Terry

Hi Terry if you have the tracking
generator you might like to look at this page from my web

It details using an accessory,
RFZ-12 as a test bridge that you can use with LF aerials. I
dont know whether there is an "RFZ-19" as your unit covers a
wider range

3586C selective level meter for LF and MF
Hi Alan
Yes, rugged indeed. :)) They are very well built, almost too
well, with more bolts than I have seen in a hardware store, when
it comes to taking them apart for repairs. Where four bolts
would do, W&G put eight. I too, find them useful for test
equipment. I have the SG-4 storage display unit and my SPM-19
has the built in tracking generator, so it works as a poor man's
spectrum analyzer, especially useful in the low to mid frequency
range. I have found it very helpful to look at filters and
such. But you are very right when you say not to expect them to
operate like a conventional radio and they take some time
getting used to, as they were built for a very different reason
than radio reception. Nice to have, but not essential kit.

Hi Terry I have the 12 and a
3 both with PS and SPM. They do work if you are aware of
likely problems but yes they need some external help
usually. I feel it is important that potential buyers
realise that they are not receivers like they are probably
used to. They are brilliant and useful pieces of test gear
and the W&G kit is very ruggedly made.......you need
to be a bit rugged yourself to hump some of it around :-))

Hi Alan
I would be interested to know which W&G selective level
meters you have. I have the SPM-16 and the SPM-19 and use
them with a preamp and AM broadcast band notch filter. They
seem to work reasonably well and signals compare well to my
Flex 5000 with a Palomar Engineering VLF upconverter.
However, I live in Canada and we have very little in the way
of MW stations other than NDBs operating on the bands. I do
from time to time pick up MW stations from France, Germany
and Iceland.
