I haven’t guessed even once! In the USR (on the MRK board), you need to put the 11th leg of the K174XA11
on the ground (to increase T APChiF) and that’s it.
Clear skies to you, Valera (Dragon).
Turn up the line frequency on the USR (such a board is on the radio channel module) or
the frame rate in vertical scanning. If the image stabilizes, then
it's all about the XI shaper in the Spectrum. The second option is that the quartz is unstable,
or not at the required frequency. It is also possible that the video signal level is too high.

the color module MTs-2 or MTs-3?

if it has MTs-2, then I can say unequivocally that USP is not on it
as a separate board. But you can twist it :)
The coolest thing is to change the MC-2 to something newer, for example
MC-3, there are RGB inputs specially designed for such things.
Good Luck...
... Gotta run, cat's caught in the printer...
KT315 transistors with collectors at +5V, bases for the output of the RGB sinclair, emitters
for the RGB inputs of the TV. 0V sinclair = 0V TV.
Resistors ~10-1 kOhm (preferably trimmers ~47 kOhm) from emitters of transistors at
0V.

So this is the MC-3 itself, only I didn’t find any inputs there.:(
And about the inverse ones I learned the matter from Radio 2-3© 1992, there is a diagram for connecting ORION.
In general, my Spectrum connects to any imported TV via
SCART.

I know. The above-underlined phrase was written specifically to prevent a person from starting to twist the coils in the submodule. In my naivety, I didn’t
think to add that MC and MRK are different things :), assuming that since
a person got into the TV, then he must have basic knowledge :)
MR> But you can twist it :)
Yeah. It is necessary.

What does the color module have to do with the synchronization module? ;)

then the USP on the radio channel is not in the form of a module, but is located on the board.

yeah...
TY> 2MM: to replace the MC-2 with the MC-31, no modifications are required in the TV.
I will even say more: to replace the color block starting from MTs-1, to
any other - more modern - alterations are no longer necessary. I
installed mts-63 :)
TY> P.S. But what does synchronization have to do with the MC? :)
none. She is separated in the dark for a turn... Lana, let's finish...
otherwise they will say that it is offtopic..

And even better on the MTs-41, but in no case MTs-46.
Now the color MTs-555 has appeared, it shows the steering wheel, but I haven’t
connected the speckie to this.
If they said how to connect, then sorry, but I’ll tell you my IMHO.
So, first you need to carefully remove the radio channel module MRK-2 (SMRK-21),
and make sure that there are 2 in it diode KD522 and a 100KΩ resistor.
They are located in the input circuit of the “blocking” signal; if they are not there, then install them in
the appropriate places. Next, make sure that there is a 4.7 μF capacitor at the
LF input of the same module; if it is missing, then install it.
All of the above modifications may not be necessary, but as a rule
manufacturers do not install these radio elements. Synchro is supplied to the output
PTsTS (Video).
Next we connect to color chromaticity block, it is advisable to run them through diodes
KD522, if there is a “window” signal on the chrominance module, then it is necessary to send synchro from Specky to it
through KD522.
The principle of operation of the blocking is
connected to the case - the blocking is turned on, TV-monitor:).
disconnect - again just a TV:)
With best...

mts2 - rulez of rulez
you need to hook rgb to the trimmers (center) so that the white level is turned, through
resistors 200-400 ohms (in place), in parr im conder peak at 30
the connection to white is ideal, both on zx and on ibm (cga-ega-vga-svga) required
polarity, maximum possible clarity (bandwidth of at least 20 MHz)
take the rgb output on zx directly from 1531kp11 - then the switched off zx
has no effect on TV reception (no need to unplug the cord)
