What are the radio setups in some of your cars? Attached are a few photos of what I have in the 73 M-M combo along with the harness going to it which is cutoff short and terminated just under the dash behind the firewall insulation to give it the look that it is running to the radio unit which would have been under or behind the seat. The radio is a Motorola Mo-Com 70 and the siren setup is a GE Power Call/Siren.

The next photo is of my ex-girlfreind Medusa's hair do!!!:4_11_9: Actaully it is a photo of the wiring harness all cleaned up ready to install on the backside of the Mo-Com 70 in the combo just to show what it looks like. As I installed the harness I tried to get the numbers on the wire pins matched back to the back of the radio head to.

Jeremy: A Mocom 70 would have had a remote mounted box (with all the guts) and heavy cabling most likely to a spot behind or under the seat, or in a space available in the patient area. With the "Standard-Extender" Slide Switch your original system was most likely a Low-Band versus VHF or UHF. MM

Jeremy ntalk to Brady about his setup that We Installed. He may have pics of it Including the control box behind the Seat.
Nice Job on Your Setup

If you were closer. Doug House could set it up for you and most likely get it working.

Boy, that Bill Leverett sure says nice things about me. I must remember to find something really cool for his new-old Cadillac! :thankyou2:

Seriously, I do enjoy working with vintage radios, especially the old Mocom/Motrac styles, and have managed to get my two ambulances talking to each other. Here's a pic of the installation in my '68 Pontiac Superior.



2071

You'll notice a slightly more modern HT1000 portable radio in a Converta-Com as well. I know it's not correct circa, but it has my work frequencies in it. Gotta stay in touch....and the guy with the most antennas when he dies....wins! :)

Here are a couple of shots of the Mocom radio system in my '75 Criterion. The siren is not original to the car. It came with a PA-100 which was, unfortunately, damaged beyond immediate repair. However, the PA-20 is correct circa for the car.


2075

2076

My Criterion may be rusted all to hell, but by gawd, the radios work!!! 4-channel scanning capability plus a 12 watt amplified speaker...brand new! I love Ebay!


My priorities may be a little bent! :stars:

I did actually give it though about fixing the radio to where I could possibly talk to other PCS cars when at meets but from what I understand I'd have to get a FCC licence to do so. But something I am working on is looking for and finding sound clips of ambulance radio traffic and burning them to a CD or creating a MP3 file and hooking a small CD player or an iPod to the Motorola speaker and having the dispach playing during car shows and cruise-ins. Now where can I find and download the radio traffic that I'm looking for? I've tried to download the "Dallas Police Tapes" but haven't been able to do so as of yet.

That's a great idea Jeremy. Someone, somewhere must have some old radio traffic recordings.

Nice and clean Jeremy but where is your siren?

I see on the Federal Interceptor it has a radio function. Was this ever used for two way communication?

The "Radio" function on the Interceptor allows your two-way radio incoming signals to be broadcast through the PA speaker, allowing you to monitor the radio while out of the vehicle (but close by). It's not a two-way function, as it allows for listening only. Back in "the good old days", we used to park the ambulance down at the beach and enjoy our lunch in the sunshine, monitoring calls through the PA. A pleasant memory, actually. :)

Hey Doug...and then someone would pull up next to you and key their microphone...the feedback caused your ears to bleed!

That was you, Bill? What a brat. 35 year later and I still don't have all my hearing back! :bonk:

My question is which one of the two of you want to come mount my radios? That was pretty good work on both your parts. I have been meaning to mount the radio in the 76 and soon the 64. I really had to do some rigging in the 70.

Ron, it's really a pity that you don't live up this way. I would be more than delighted to give you a hand with your radios. :smileflagcan:

I know of one PCS Member that sent another PCS Member a round trip airline ticket to come to his home and do some "repairs". Wined, or is that whined and dined him while he worked on the "cars". I am sure that you could do the same to get someone to work on your cars...

Hmmmmm....and as I recall, the certain someone was a fellow Criterion owner! :agree:

before this post degrades into something else here are the ones in my or now Steve's 72. now I did not hack up the dash and cram that pa 15 in there but someone did. piece of ready rod screwed to the back and down to the steel frame of the dash to hold it up in back.

gettig old I swear I up loaded the pictures. now when I did ht emike clips I put them right were the old screw holes were. so I never drilled a hole in my dash.

Doug House

That's quite the interesting installation, Ed. I"ve never seen the dash cut out for a siren like that before. Years ago, B.C. Ambulance Service built their own ambulances, originally Dodge Type 3's, and they put the Midland LMR two-way radio in the slot where the factory music radio would have gone, but no cutting was required.

Do you have the main radio portion of that Motorola Micor, or just the control head in the picture?

Thanks for the pics! :thankyou2:

Doug I did not grab the radio when I picked up the control head. one of the oops in my life, but then I did not intend to put it on line and the extra 50 lb briefcase was something I did not think I would need. they did put this siren were the radio should be in this car. wiped out the cigar lighter to. I though it was some one else that just cut the hole and stabbed it in but when I looked in back the ready rod was bent and washer welded on top for the screw into the case. so it was not a hasty done thing. just one more of the strange things done in this DOD car.

I must say that it looks very cleanly installed, Ed. Although it's a pity that the dash was cut, I'm sure that no thought was given to the future, but rather to just making it functional at the time. Admittedly, that installation does keep the siren nice and close for tone changes while driving.
