Re: S-85 refurbish: I've got a problem during the RF alignment of bands 1 and 2 - trimcaps don't peak!

 

¿ªÔÆÌåÓý

Richard what does turning the dial clockwise ?actually mean? If it was a rotating pointer on a fixed scale it is fairly clear that the POINTER rotates CW. And the numbers stay fixed, but on a rotating scale with a fixed pointer, the physical scale might rotate CW but the values on the scale might be going up or down as you rotate. If they had a 1¡­100 scale ?one could just say turn it to position 1 or 100, but? I fear the use of CW,CCW with Rotating dials or Rotating scales ?can be confusing.?

?

the condition while attempting aligning is that there might just be too much capacitance.. obvious on two bands in 2 tanks each.

So now in this wonky situation, just to see what id going on. Ignore all that and try to get the tanks to resonate higher?? ?by ensuring the ?BS capacitor rotor itself is wide open. ?I thought Emanuele said he did that, but I¡¯m not sure. ??

Note that the direction of the dial and knob for bandspread are
reversed. See instructions about replacing the dial string. The index
mark on the dials is at the LOW end, with capacitors fully meshed. I
read this over carefully. The _band set_ position of the band spread is
with the dial at the high frequency end of each band, that is, capacitor
UN meshed. but the instructions for setting the dials is to fully mesh
the caps and use the index mark at the low end of both dials.
Also, a note states that the LO is at ABOVE the signal on all bands
except the highest (band 4) where it is below the signal (as I suspected).
The problem with clockwise and counter-clockwise is whether this is
the knob or dial direction, because they are opposite. However, looking
at the capacitor plates is unmistakable. Fully meshed for dial stringing
and setting the reference of the dials, band spread fully open when
setting the main dial for frequency and for alignment.

Emanuele, this is late.

Your statement here seems to eliminate the idea that the BS setting is the problem.

The other day while taking my truck tire off at a tire place, the hex part of the security nut shattered, leaving a small bit holding the wheel on and no way to get it loose.

Finally today a mechanic guy worked and worked and finally got it out. It takes persistence sometimes.

But I checked it and, in fully clockwise position (the one indicated for alignment), the cap is at minimal capacitance (blades all out).

Re: Missing page S2001A

Thanks Pete. I appreciate the complement.

I find it very gratifying that my work helps someone bring a piece of equipment back to life. It also provides me with the joyful option of bringing a possibly bug invested, stored in a garage or basement for 50 of 60 years into a worthwhile and useful document that others can read, use and enjoy.
?
Of course, one can find poorly scanned, incomplete, and highly marked up pages all over the Internet, but even when printed, crap is crap, and stuff is always lost in the transition.
?
I just finished a military manual for a customer. Roughly 200 pages but easy to do even though every page, because of age, was brown. My machine can remove background paper color. But the hicker and hard part, were the five schematics. They were 14 inches high and 52 inches wide. And I decided these were to be done full size. A customer never has to assemble and tape any of my manual pages.
?
This entire project started back in the mid 90's as a bonding project between father and son. Son was in his second high school year but didn't seem to have any idea about his future life endeavors. Since I was dragging boatanchors home to repair and get up and running,?from every hamfest I went to, my collection of manuals for this stuff started to become a pain to manage.? My son created database to manage all the manuals that I also kept collecting. He also suggested creating a catalog booklet, advertising in Electric Radio and a few other publications, and send out the catalog to all interested parties.? I firmly believe this gave him a sense of business activities and helped firm up (or at least give direction) to his future. He also created my first web site and credit him for giving it its name.
?
After? high school he worked for a year before applying and being accepted at Boston Bible College at Hyde Park, MA. He felt he should earn the money to pay for college rather then taking it for granted. For 3 summers while in his college years, he worked at Lucent Technologies as a contractor and used the money earned for tuition.
?
My apologies to the group for rambling, but I'm very proud of my son. I gave him a license manual when he was around seven. When he turned around 27, he finally found the time to become KB1JTP.

Emmanuel ??Oh I sent? more cross-posting.

Now back at square one ?

Entropy is increasing quickly.

So you are back to the apparent ?too-much capacitance or inductance, and similar problem for 4 tank circuits.. strange¡­

?Emmanuel ?we don¡¯t know the history so presumably this radio is new to you. did it ever work ok on band one? Is there a sign of somebody mucking about around the coils and bandswitch. Could there be a cross between band one and two tanks maybe due to little clearance?...another longshot

Now I am just wondering out loud, the RF for the 2 HF bands seem to use transformers with slugs, and you can see them on the layout, but for band 1,2 there are trimmers shown but no transformer or coil on the layout so perhaps ¡°L3¡± has a simple winding for band 1 and another for band 2 ????? same situation and question for the mixer tanks? So what would happen if L3 had a common ground connection terminal and a bad connection to ground ? OR something? ??could L3 have been changed ?another longshot

Another thought; I wonder if the alignment instructions are as complete as for older radios.? My thought is that both ends of the oscillator should be set first and any interaction eliminated by repeating the C22 and C25 ?adjustments etc, then set the RF trimmers. It is hard to see it making a big difference¡­ Richard, Emanule, whoever??

A last resort might be to? find the resonant point of each tank at the top end and the bottom end of the main tuning for bands 1 and then 2. ????

Richard has just added some confusion so this is going now as-is only thoughts.

Re: S-85 refurbish: I've got a problem during the RF alignment of bands 1 and 2 - trimcaps don't peak!

 

Where its supposed to be I think.
As far as your last post, I was looking for something like this. I
was tempted to suggest getting rid of the high tech instruments and
sticking to a regular signal generator as prescribed in the
instructions. This is really a very simple receiver and should be easy
to align. Remove as many variables as possible, such as a spectrum
analyzer and sweeper. Maybe after doing an alignment with the simplest
tools. A modern signal generator will have reasonable calibration
accuracy for both frequency and output level. A counter or even just a
crystal calibrator will do for adjusting dial calibration. The spectrum
analyzer is helpful for signal tracing, if necessary, and to determine
which side of the local oscillator the signal is on. On the broadcast
band its possible that if you are on the wrong side (will be below the
signal) you will simply run out of range at the low end. That could be
what is wrong. Actually, a simple broadcast receiver should hear the LO
and tell you where it is. Should be the signal frequency plus 455Khz.
Obviously, if its tuning below the signal it will probably stop
oscillating at some point. At the lowest frequency of the broadcast
band, usually 535 Khz, the LO would have to be at 80Khz. Might be the
reason it stops working at about mid band. Again, its likely the top
band is opposite of the others, i.e. the LO will be below the signal.
This is often the case in older multi-band receivers because the
oscillator/mixer may have higher conversion gain there. Depends on the
tube used. Unfortunately, handbooks often don't tell you this. The
assumption being the tuning will be only touch up and not far from the
factory settings. We are dealing with antiques and some of the
assumptions made by the manufacturer are simply not so.
Good luck, I think you are on your way.

Which way is the band spread capacitor facing? Capacitance should
be minimum with dial at zero. This is Halicrafters design, on
non-calibrated band spreads the dial indicates the amount of capitance.
I think calibrated dials are set for the logging scale to be the same
but in any case the band set is generally at the high end of the band.
The dial cord is backwards of its orientation on later receivers
like the S-40. The string crosses over.
BTW, I wondered about this. My S-40A came with the band spread
string reversed and stop peg facing the opposite way to that shown in
the handbooks. I reversed it. In its original position the band spread
went from zero to 100 but in what I thought was the correct position it
stops at about 95. Same for the S-20R. It made me wonder if the original
position was correct and there is a global error in the handbooks for
all this series of receivers. The position as shown in the S-85 handbook
seems to confirm this. A puzzle. At some point I will try reversing the
cable in both receivers. In any case, at ZERO the band spread is at
minimum band spread capacitance, plates turned out from stator, this is
as it should be regardless of the cord.

Wait a minute guys ... SORRY guys!!!!!
?
Using the SA for RF alignment led me astray, .. and you all with me!
Don, you say need education ... from my side I would say I need a medical treatment for my brain!!
?
We are not looking for the peak at the resonant frequency, as you would do aligning an IF, but we are looking for the MAX at the indicated frequencies. Operating this way the? entire response curve of the band takes on an ideal shape and the peak will be placed approximately in the middle.
?
This picture sketches what I mean...
?
Looking that happenin in real time makes things much more clear.
This also explains why the radio is performing well.
?
Still, band 1 & 2 won't get to a MAX at the indicated frequencies.
Releasing the TRIMCAPs from fully tight to fully released the signal (and the entire curve with it) goes always up and never down until the TRIMCAP reaches its end stop.
I would say: they go to "highest possible value"...

here is my picture interpretation:

Richard:

¡¤"/So, what is this about .5Mhz and /*/370/*/and /*/220/*/Khz?/ ". Those
are the delta values between peak and the desired frequency as reported
by the Delta marker (rounded).

¡¤The IF alignment has been remade from scratch by using the "visual"
approach (first 3 pictures).

¡¤"/The position of the peaks on the RF will be affected somewhat by the
dummy load/". If you meant the "dummy antenna" *I fully agree*. I'm
gonna try the same test removing the dummy antenna from the equation.
I'll report as soon as I get time to work on that.

Correction to my previous post:

"/...all signals (and the noise as well) tend to disappear below /

the band.

Re: Missing page SR-2000

Obviously, as the old saying goes, "you get what you pay for". A lot of the manual stuff floating around the Internet is of poor quality, poor readability, questionable completeness, and a wonder if the person scanning the document did it with one or both eyes closed. And personally, I really don't care what you do; some people?are happy with?expectations that are lower then others. Been doing this stuff for roughly 30 years with customers in all 50 states and 150 countries,? so there are many that value the work. Plus, I also do speciality manual replications for several amateur radio retailers for resale. And if the demand ever goes to zero, we'll have a lot of fun at the paper recycling center.

Hi all, many of us are following along with the forum, trying to learn and/or help, and certainly cannot afford to buy a manual for every rig, let alone every version, so professional manuals are not an option for us; unless maybe we happen to have the exact rig in question, in which case any proper manual copy should do for me at least. If somebody is in the business of turning rigs over for a profit, it would be good to have a good exact copy, of an unmarked, archived manual. ??I have no idea as to who to go to for the quality I might want.

Wrong versions can be a problem, at least with Halligans stuff.? And PS, I am just thinking out loud in my situation; others are free do likewise.
