Thanks for reading this message. Maybe you can help me out with my
dilemma.
Recently, I sat down to adjust the S-Meter on my old Kenwood TS-520S
transceiver, as per the Service Manual. The manual stated that the
S-Meter reading should be adjusted to read S9 for a 40dB signal received
at the antenna at 14.175Mhz. Before I commencing the adjustment, I
decided to compare signal strength readings of the TS-520S to a new
Kenwood TS-50 transceiver. At 14.175Mhz, both radios read the same static
level of S3. Both radios indicated the same S-Meter reading of 20dB of a
QSO I was listening to on 20 meters. So what's the problem you ask?
Well, If I am to adjust the S-Meter on the TS-520S as per the manual a S9
reading would indicate a 40dB signal. For the same siganl on my TS-50
radio, the signal would read 40dB. I always thought that regardless of
the type or make of an S-Meter, they should read the same for any given
signal. Is there an error in the Service Manual? Should I adjust the
S-Meter as detailed in the manual? I would greatly appreciate your
thoughts on this one.
