NeptuneMan got a reaction from ke0eyh in Kenwood Tk-862G repeater build
Firstly, glad to finally be here. Been a lurker for a while, and the FCC got back to be a few weeks ago, so now I can key up
Back story summed up, I'm working on a repeater for my family using a pair of Kenwood TK-862G/HG mobile radios (the 862G for RX, 862HG for TX @ 25 watts). I know there a lot of 'better' options out there for repeaters and mobiles aren't the best of the best, but its what I've got, so I'm using them. I'm also using Tk-863G for mobile units and looking for TK-3402 HTs, but they aren't 'part 95a'....oh well, still looking.
Current situation, I'm trying to interface the two radios using the KCT-19 accessory cable. I didn't want to use the front mic ports, (I wanted a clean look in a cabinet) I figured the accessory port would be fine for this. But, I cant figure out the pin-outs. I figured I could just take RX unit and run Receive detect output (CN4 #1) to the TX unit External PTT input (CN4 #7). Plan was to use CN4#1 to activate the PTT and just route audio out from RX to the mic in on TX. But that didn't work...anyone got any ideas? I think I'm having issues because one is an active hi, and the other is active low?
I'll try to attach any information needed, .pdf, pics, anything anyone needs. The pic shared is the PCT-19 accessory pin-out. CN1 is used for a separate control unit (I believe GPS), so ignore it. CN3 is horn alert, CN7 is PA..so disregard those too. CN4 and CN8 where the logical ports to use IMO.

NeptuneMan got a reaction from Extreme in TK-8180 Dash Mount?
First thing I do is look for the radio brochure, its got all the add-ons that are available for that radio. https://manualzz.com/doc/8325970/kenwood-tk-7180_tk-8180-brochure
Personally, I'd go with the remote head mount for the dash, unless you don't mind the full radio mounted up there. The remote head just gives you more location options. https://www.amazon.com/Kenwood-KRK-10-remote-control-NX-700/dp/B00R8M3ZWI
I've removed my rash radio in my '98 Ram, replaced it with a BCT15X scanner..I listen to local FD/PD more than I do the radio.

Most definitely, Steve. Unfortunately, this is the definition of a back burner project. For example, I've had a 40ft Rohn tower for about 6 years, and its not set up yet But of recent, the project has gained quite a bit of traction, so I doubt this repeater build will take that long to finish....hopefully. I do plan on doing lots of pictures and a detailed reasoning/breakdown on equipment and why I chose what I used.
At the very least, I'll throw a bit of eye candy (pics) of what I'm working with in a later thread.

Upon further discussion,a relay just isn't necessary. A NPN transistor is more than adequate (I'm just use to larger, higher amperage electronics in my work like relays...I'm more mechanically inclined than electronic).

I had completely forgotten about the Tk-370/372! Thanks @Lscot
A friend helped me out a bit to figure some stuff out. I'll be using Squelch detect output (busy high, 5v) (CN4 #8) on the RX unit to signal the TX. Problem is that the PTT is 5v active and needs to ground in order to key. My plan was to use a 5v solid state relay controlled by SQL out on the RX, which would ground PTT on TX upon receive.
