I think I have a problem, and it's not in Houston....I got the 80
band tuned up on my SB-101, so I thought I'd try it on the air..I
found an 80 meter LSB group of hams talking ,and having tuned up the
101' into a dummy load, I turned it onto the antenna and
called...they came right back and said I had a nice signal...no
tuner...I asked "what frequency are you showing?" and he came back
"3900khz". Only one problem...I was tuned to 3691khz!! I checked
this again on 40 meters...same thing...when I transmit a signal
using my Elecraft K2 on 7400khz, the 101' is reading (and receiving)
it on 7181khz...Did I do something wrong with the LMO? I checked
it's range of movement,and with the tuning unit dialed all the way
counterclockwise, the variable cap is almost closed; then, five
turns to the right and the cap is fully opened, as I recall. I
didn't check it on any other bands, but at the moment, it would seem
the LMO's output is 219khz too low....right? It's reading 219khz
low exactly on both bands..... Help....<br>
<br>
A bit of history. I know virtually nothing about the history of
this 101'....I bought this one, with another 101' and two HP23
series power supplies from a nearby ham for $100. He had bought
them from another ham, hoping to get one working one out of the
pair. He never had time to delve into either of them....<br>

Thanks for your help....I followed some of your
advice, and the advice that I didn't follow came
back to bite me.....I acquired a couple of SB-101's
for a song (well, a song plus $100, but it included
two power supplies....)....and I've been "bringing
the 1st one 'back'" so to say....cleaning, checking,
going thru the tune up routine, etc......I rebuilt
the LMO on an SB-101....removed the front panel, etc
to get to it...had to do a lot of general cleaning
as the entire dial assy was all gummed up. I took
apart and cleaned the LMO...lubed it, removed and
cleaned the stops, but<i> I didn't do the braid
thing</i>......I used a high end light oil for the
lube...from Kroil....I got it on the air last night,
loaded it into a 75 ft long wire w/ no tuner and
joined a group at about 3800kc or so but they kept
reporting I was "jumping all over the place"...as I
listened, I heard them, but the frequency kept
changing...or "warbling" as you say. My signal was
plenty powerful, and the group was spread out all
over the California coast up past San Francisco...so
the 6146B's were really kicking, so to say. So, I
reread your email and this time, downloaded the file
on LMO rebuilding. I'm going to attempt removal of
the LMO w/o removing the front panel--can I do
that? Maybe I'll have to remove the "escutcheon"
to set the dial on right...Anyway, now I think I've
got to do the braid....I was going to use a bit of
"soldering" or maybe I should say "de-soldering"
braid...Is that ok? Anyway, I should have followed
<i>all</i> of your advice, not just some of it. One
other interesting thing....when I tuned in the
stations, my RF gain control didn't work, and when I
looked at it, the diode on the middle terminal had
let go...but wow, did the receiver<i> have a lot of
gain</i>. When I hooked it back up, the gain
seemed to back down a bit. I thought I'd play with
that just a bit to see if the control is somehow
hurting the overall receiver gain...<br clear="none">
