S-meter setup for Kenwood TS-50

[Curtis Eickerman]

If you want to use the service menu to set the S-meter on a TS-50 (A5
for S1, A6 for S9, and A7 for full scale), what frequency is the
receiver operating on?

I suppose I could just start sweeping around with a signal generator,
but just wondered if anyone knows.

Curtis-

I've had my TS-50 ever since they came out and didn't know you could do that!
I did check it once, and found that the "standard" 6 dB per S-Unit was not
observed. Each S-Unit was different.

I would assume the receiver would be operating at the frequency it was adjusted
to prior to entering the service menu. Many times a service manual will
recommend making adjustments of this sort at 14.000 MHz, but I think you are
expected to set frequency with the tuning dial before starting the alignment.

It's not common knowledge, but there is indeed a service menu for the TS-50.
I also thought that when you go to the S-meter setting menu items it would
be on the same frequency where you left the radio. However, when I go to
the menu items for the S-meter settings the radio clearly changes frequency.

You have to use a signal generator when setting the S-meter. You provide a
signal level you want to be S1 then hit the Up or Down key and the present
reading gets transferred to a holding memory. Then you change to menu item
AD and hit the Up or Down button again to save the setting (otherwise the
old setting is retained). You repeat the process for an S9 signal, and once
again for a full scale signal.

I went ahead and changed my S1 setting without a signal generator so that
background noise was S1. Before it was set so that it took a substantial
signal to even get the meter to read.
