Re: TS-690S transmits on 6m but not on HF
|
I have been following this thread, so I thought I would take a look at the schematic and have come to the conclusion?that Jordan is correct in his observation also.? Good luck.
Ok...
?
Given the voltages shown, I believe it's safe to
say that those are RX voltages, followed by voltages in TX in parentheses...The
850S manual?uses the same scheme...

TS-690S transmits on 6m but not on HF
Bob,
?
As an example, page 137 of my PDF copy of the service
manual has several test points with two voltages shown. The second voltage is
in parentheses.

I looked?at the PDF. I cannot find a "legend" that
states what the voltages mean. Some voltages are in
parenthesis????
It does say "tx" on some of them.Maybe Jordan can tell from
his regular service manual.
?
I'll have to break
out my actual service manual rather than rely on the pdf version. I'm sure
there is a legend somewhere but it's?very time consuming?to find
in the pdf.
I'm tempted to say
those voltages are in Rx and then Tx but I'm not 100% certain of
that...Maybe someone else knows, but in the meantime I'll pull my SM copy
and check when I get a chance...

Jordan,
?
I’m just now getting used to the layout of the service
manual, so your pointers have saved me a lot of time and
frustration.
?
Any idea what the voltages in parentheses represent? I’m
sure there’s some sort of explanation somewhere in the manual, but I
haven’t found that yet, either!
?
I’ll report back what my measurements show.
