That's interesting. I bought the old 1530 about a year ago. So the
"plus" has that much more gain? Sounds like a good deal. I know
that by the time I finished my not-so-rigorous research on the
Internet last year, trying to choose between the 1530 (old) and the
330, I decided that for my purposes and favorite frequencies they were
about the same. If I remember correctly...and I don't always....I
think the 1530 seemed to produce better results lower in the spectrum
and the 330 better up around 20Mhz where I seldom go. At any rate,
my 1530 does very well at my location from LF to SW, including 21 Mhz,
so I'm pleased. And....most important to me...it all but eliminated RF

I made a pair of 'Wire-to-Coax' adapters to allow the use of LMR400 coax, for example, on MFJ Loop Tuners. I have the 933 and 936B Loop Tuners. LMR400 and LMR600 are much thicker than the usual #10 wire and 1/4" copper tubing usually used. The center pin and shell/shield of the SO239 are soldered to the 1/4" copper lug used to make the adapter. I suggested to MFJ that they make something like this for their customers, since more people are using thick coax for Magnetic Loops these days and it is easy to get well made coax cables of various lengths, for ease of setup.
There are 2 'Wire-to-Coax' pictures in the files area from 'daiche' for you to view.
