provision for external 9V power, as well as an earphone jack for
Obtained from England, the
Lowe FX-1 reminds me of an
updated (but much prettier)
version of the Midland-series.
It also has a slightly wider frequency coverage of
0.7 - 250 MHz. Like one
of my favorites (the
stores its coils within its case: a plate on the back has a small
thumbscrew (fingerscrew? <grin> ) and a compartment wherein the coils
are stored. Overall, a very nice unit, with several attractive features-but
all Lowes are not equal. In order for an FX-1 to function as a GDO,
there is an entirely separate circuit that must have been added. Look
for photos here soon.

complete with the suitcase carry-a
beautiful instrument in incredible shape;
this unit was believed to have been a 'Salesman's Sample' but apparently
was not carried around much, if so. Also I have a partial body for
parts; the 59LF Low Frequency Head; and (obtained separately from the
above GDO) the 200-900MHz

considered a modernized version of, the

covers 1.5-250MHz in 6 bands. My used one came with
the original box, instruction sheet, and all coils-even the
still-wrapped orig. 9V battery, in AS-NEW

has an FT-243 socket
for crystal testing.
Available new, it is a
very good GDO for the money: accurate, portable, and reasonably rugged.
Very similar to the

is a band-switching GDO, covering from 1.75 MHz - 34.8 MHz in 5
bands. A frequency counter can be connected to the "FREQ OUT" RCA jack
accuracy. It manages bandswitching-instead of multiple plug-in coils-by
putting the coils inside the box, and using a single plug-in coil for
coupling. I believe that is the primary reason for the greatly limited
bandwidth. It uses the standard 9 VDC battery, mounted internally. I
obtained this one some time after manufacturing ceased because Amateur
Electronic Supply still had one on the shelf in Florida. MFJ was absolutely no help in my
quest for one-never even replying to my inquiries.
