Re: DR7 fitting partial success.
More likely it is a broken trace than anything else. The display board is a nasty bugger to unsolder. The LEDs are a standard off the shelf pinout, you could replace them if bad. Not that I am

Re: DR7 fitting partial success.
Thanks Joe By multiplexed do you mean the bank of resistors (I think 100k) going between the KHz segment and the Mhz? Will look at those as well. Kind Regards Mike G3ZCC

Re: MN2000
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

Re: DR7 fitting partial success.
Hi Gary Funnily enough I made a strip out of clear acrylic which I put on the shelf where the? bulb clips on. Also put one over the lower level cover and cut out holes for the wires etc. By bad foil

I ment the MN-4C, I don't know why I said the MN-2000C...... I've looked at the Murch tuners as well.

Hi Jim Managed to repair one of the spare PTO's all fitted back and seems to be? working ok. Not putting the front back as I am changing the bulbs to blue LED's. Then to the DR7 will check through

Re: MN2000
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

Re: MN2000
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

Re: DR7 fitting partial success.
I have 4 TR7As, one of them I purchased new and none of them have anything glued to the top of the PTO can. I also currently have 3 TR7s with serial numbers in the 9000s and none of them have any

Re: MN2000
Look for a Mutch UT-2000B (not the A). They go for short money and will load up the proverbial bedspring. 73, Dick, W1KSZ ________________________________ Sent: Sunday, March 21, 2021 9:16 AM To:

Re: MN2000
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.

Interesting. I don't recall having seen this. Fish paper maybe? 73 -Jim NU0C "Gary Follett" <xntrick1948@...> wrote:

Re: MN2000
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

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,

Re: DR7 fitting partial success.
Did you check that there is an insulting strip loin top of the PTO mechanism? There is a very close fit between the bottom of the DR7 solder and the grounded metal below the DR7 just below the display

Billy: 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

Re: MN2000
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

Re: DR7 fitting partial success.
It looks like you have an aftermarket LED board from DF4NW. Nice! However that suggests that someone botched the install and gave up on it. The display is strobed. One set of segment drivers drives

Re: MN2000
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
