Has anyone ever modded an MN2000 to work on 160? That’s the only thing that has kept me from snatching one up to add to my C-line I have.
|
Put up a 160 antenna and use tuner on 80-10 !? 73s Byron AC9PA?

I seem to remember seeing a 160 mod a long time ago. Unfortunately, it involved drilling holes.?
At a minimum, it would involve adding inductance and fixed capacitors whilst using the bandswitch in the 80m position.?

Hi Billy
I would think it near impossible to add 160 to the MN 2000.
It looks like a high Q circuit and I read somewhere that it performs best when using antennas of near resonance and is tetchy on 80m.
As has been said, you would have to add inductance, probably to the 80m section of the coil and also parallel capacitance as a minimum.
Look at the tuning capacitors in the schematic, way too small for Topband.
You would have to fit some kind of switch, not a good idea imo.
Simplest thing is to to put up a Topband quarter wave antenna and use the MN 2000 in direct mode.
Better still make a separate ATU for Topband and paint the case the same colour as the MN 2000.
How about one of the MFJ Autotuners?
Back in the 60's when I got licensed, we were limited to ten watts , I used a 132 ft long wire with an ATU, in those days built on wood.
Topband can be very forgiving, I have worked over 200 countries now and also a member of the Topband Hall of Fame.? ??
It is my favourite band my first DX was Stew W1BB and Ralph W1HGT, that really whetted my appetite.
Good luck with it Billy , hope you sort something out.
?Kind Regards

Indeed, the MN-2700 might be a better choice for 160m than trying to
convert an MN-2000.? 160M coverage is already built into the 2700.
It won't quite match your 4-line for sure.....but there's your
excuse to add a 7-line to the shack, if not there now!

I agree ?with Peter. ?In fact, I use my MN-2000 for 40 meter operation but use my MN-2700 for all other ?bands due to ?the wide matching range. ?Once you find the sweet spot for each band, logging the settings (including the extra capacity lever switch controls) makes tune up very easy.

I've been looking at the MN-2700 but like said, it doesn't really match, would love to find an MN-2000C which is an MN-2700 in the 4 line colors which are a little harder to find. I do actually have a 550ish ft. horizontal loop up already that I'm currently using a Yaesu FT-1000MP with but it has a built in tuner. I want to use my Drake, but don't want to mess anything up with it.
|
We have a huge hamfest coming up this next Saturday in Sevierville that I'm going to keep an eye out there and see what I can find. Thanks everyone.

Look for a Mutch UT-2000B (not the A). They go for short money
and will load up the proverbial bedspring.

Billy:
An MN-2000C?? Never heard of this one and I thought I knew of all
the Drakes including the commercial marine reserve gear.? There is
an MN-4C for sure (have one) which looks like an MN-7, but matches
the 4-line, though not as well as the MN-4/MN-2000.
Someone mentioned the Murch tuner - it's black - wouldn't look bad
at all next to a 4-line.

I was just thinking the same thing. I have a Murch sitting atop my MN2700. And a second homebrew knockoff awaiting cleanup. Spent less money than a night on the town for both combined. 73 -Jim NU0C On Sun, 21 Mar 2021 16:45:41 +0000 "Dick" <w1ksz@...> wrote: Look for a Mutch UT-2000B (not the A). They go for short money

I ment the MN-4C, I don't know why I said the MN-2000C......
I've looked at the Murch tuners as well.
|
My Murch is green. But it's not a "B" model. Someone had butchered it with cheapo verniers that were worn out. I actually found a pair of period correct knobs molded in green plastic to restore it with. It looks ... interesting. :) And I really don't care that it doesn't match the rigs. It should be noted that early designs did not have a bypass switch, which is not a big deal for a single band use antenna that needs it. 73 -Jim NU0C On Sun, 21 Mar 2021 10:22:00 -0700 "VE7PS" <ve7ps@...> wrote: Someone mentioned the Murch tuner - it's black - wouldn't look bad at

Well if where talking tuners ! Ten Tec L tuner works but cost is high .

This is the tech behind the Murch. And also why you find homebrew variants. 73 -Jim NU0C On Sun, 21 Mar 2021 13:22:00 -0500 "AC9PA via groups.io" <byroncordes@...> wrote: Well if where talking tuners ! Ten Tec L tuner works but cost is high .

I have several tuners, including the Murch.? It was popular because the roller inductor Ultimate Transmatch had huge popularity in the late
'70s.
In the end, that roller was a pain, and not really neccessary. The Swan tuner with a tapped inductor became my favorite!

It's another brand of antenna tuner made by Murch Electronics.
|
I know you're going for the look, but
if you just want to get on 160 cheaply, pick up one of the MFJ-986
or similar - the differential T-Tuner.? A fast and easy to use
legal limit option, usually plentiful at an averagely stocked
hamfest.
