Lance;
My machine is way older than the CR series. I saw a picture and PDF file for
them and their vintage is newer.The power supply in my unit has a huge heat
sink. Mine has N type Tx and Rx connectors coming out of the top of the
cabinet, they weren't being used when I got it. The receiver had RG 142U
hardwired to the input which ran directly to the cans. I drilled a hole and
installed a chassis mount BNC connector and put in a BNC to type "N" jumper in.
I also installed a jumper likewise from the Xmitter to the other "N" conector
coming out the top. I'll see if my friend can take some photos to send to you
so we can indentify it. Hopefully with that info I can obtain some sort of
service manual or at least a schematic. I hope you can come up with what I
need. I have several other machines on the air even as we speak, but this is my
first Johnson, but it was free and I've got too much time on my hands, and a
local club needs a repeater so I'll "git 'r' done" and turn it over to them.
Thanks.

Check the back of each chassis, receiver and transmitter for the applicable
model numbers, the radio you have is probably a CR1000, CR1010, or CR1100
made up of basically 2 mobile radios hung on pull out rails. The later ones
have the chassis in pull out boxes, sort of like small rack units.
I may have what you need if you can give me more info, or a photo of the
insides...

Gentlmen;
Need help in Identifying Johnson Vhf repeater... No model
#, or serial # found on unit.
I recently acquired a working EF Johnson VHF homebrew repeater, has an
odd ball split. Tx freq. 148.150,......Rx freq. 143.900.
Unit Xmits 120 watts w/good audio, receiver is fairly sharp. Encodes and
decodes, 141.3PL tone. Homebrew controller with courtesy tone only, No cw ID.
Unit appears to be a mobile radio in a Johnson cabinet w/ EFJohnson P.S. The
cabinet is about 30 X 22 x 11 inches The mobile radio measures about 15 x 8 x 3
inches. The vintage is 1982... Need to ID Unit, ( PPL 6050 ???) help, and
manual if possible. Are xtals still available? Thanks in advance for any
assistance,
