I agree, it would be nice to have a single standard, but as far as I am concerned, you can blame the IARU for that. By 1981, there were millions of radios out in the public and the vast majority of them (CB's), used -67dBM/100uV/+46dBu for S9. Even amateur radio makers had different...

FYI - Anytone's factory setting is S9 = -67dBm & S9+60 = -7dBm

@Shadetree Mechanic - look for B013HK2MBE on Amazon.

my 703 schematic shows the 16 finals are RM3's.

??? On your drawing of the mic adapter, it says Cobra 4 pin. If your Turner is using the stock internal wiring and the mic plug is wired for a Cobra 4 pin (or that is what you want it wired for), then pin 3 & 4 are backwards on the Turner mic plug. Turner +3 4 pin mic plug wired for a Cobra 4...

LOL Pez. A lot of things have been talked about in this thread. Specifically, before my #76 post we were talking about using a SINAD meter to test the radios RX sensitivity. In post #76, I was specifically talking about calibrating (CH-11) FMRSSI and (CH-18) AMRSSI. You quoted my #76 post in...

Because these service menu settings were from brand new radios not previously owned. There was no assumption being made. The same reason I gave as to why I couldn't use mine... mine was used.

DO NOT DO THIS! IT WILL WIPE OUT YOUR SG (in my case, my TinySA). Do not use a SG to set the FMRSSI or AMRSSI! You have been Warned! Connect a Dummy Load to the antenna, put RF power @ max, key the mic on FMRSSI & AMRSSI to set the TX meter for carrier on FM & AM.

Jeff, May I suggest a possible solution? If you want the Clarifier to slide, here's how to do it correctly. You have several things going on, the clarifier is putting out too different a voltage which is why you can't tune L27, L28, and L29. And the Alignment is off. If you want the...

Sure I can do that but I would like to "calibrate" the FMRSSI & AMRSSI first. I sent Ken@Qixiang an email 4 days ago requesting the calibration settings for both, but I haven't heard back from him yet.

Let me clarify. "High Noise floor" is a misnomer. The radio's "appear" to have a high noise floor due to a S meter calibration issue that started somewhere after your low # 176022258 radio and before 176022258~380. The sensitivity is fine, on par or better than my other radios. Just the S...
