It<b> is</b> working; it tunes 5.0 to 5.5mhz as tested with my
counter.....only problem is that 5.0nhz is at the full
counterclockwise position of the shaft--I set it up backwards!!<br>

<div>Hi Guy</div>

<div>I would check the frequency of the LMO output with a
frequency counter before doing anything else. It should tune
from 5.5 - 5MHz plus a small overlap i.e. it tunes from high
to low when the SB101 tunes from low to high.</div>

Glen, and any other members of the Heathkit

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
