Walcott Radio peak and tune

I'm using an Astatic 636 with the appropriate adapter.

Fast shipping! That's what I use.

Not sure what the pin out is on this radio, or why they would be saying to cut pin 4. It does look like this radio excepts a dynamic or condenser microphone. So maybe pin 4 is the 8 volt supply voltage for a condenser mic?
I'm not a big fan of the RJ45 modular mic connector, especially in a mobile environment. With the weight of the mic cord and over time, the wires get exposed. Then you have to install a new connector, which isn't easy, even with the crimp tool. I have a couple of radios that use the modular jack, they would be better on a base station radio rather than mobile.

 

The 5555 with the 4 pin side mic is the radio he's referring to. I use the adapter mobile on the NII and have not had a problem. Allows you to use any readily available mic out there.

Okay I didn't get that from him, because he said he bought the 5555 n II which uses the front modular jack. Even with that jumper cable in a few years you could have the problem I mentioned. But maybe they beefed up the jumper cable compared to a mic cable with a RJ 45 connector on it. Then it shouldn't be an issue.
I've got a yaesu 2800 mobile radio with an RJ 45 mic cable, that I use as a base radio only, and the cable is still good after several years. But the radio doesn't get used as much as my radios in a mobile environment either.

 

I have my mic cord wrapped around the Peoplenet mount just below the radio on the dash so the cord isn't pulling on the plug on the radio. I've always done something similar with all my radios.

Well that's a great idea to take the stress off the cable. I did some more searching on the 5555 radio with the 4 pin jack. They do give a warning not to use a mic that hasn't been modified. It's obvious that the warning is about using a dynamic mic, but they don't say that. The radio is setup for a condenser mic which uses a supply voltage to work. The mod would probably be adding a capacitor on the microphones audio wire, but they don't say which pin it is. I guess the answer lies in the adapter cable since it works with a dynamic mic, I assume.

 

Not an issue on the NII. There's a setting in the menu for electret or dynamic mic. I believe the new 5555's have this setting too. Radio sounds awesome on AM (and SSB) with a 636 N/C mic. Not usually the case with an Anytone radio. Most of them prefer an electret mic unless modified.
