I was listening to the 20 meter band today, while the s-meter was not
giving the same signal strenght as a reference FT-757, the TS-120 could copy every weak signal the 757 could. ========================= If you want to increase the indication of the S-meter (for example because you wish it to be the same as on your other transceiver) ,there highly likely is a trimpot near the meter or in the associated AGC circuit which you can manipulate. Almost every S-meter derives its signal from the AGC. If you have a signal generator and a good quality attenuator you can set the S-meter indication to S9 with a receiver input of 50 microvolts @ 50 Ohms (-73dBm). Of course it doesn't mean that the S-meter is then correct over its entire scale , 1 S-point meant to be a change of 6 dB. Frank GM0CSZ / KN6WH |
