Free 146 GTL!!!

[Cheech]

Well I came across a 146 today in the trash down the street from me. Brought it home and it powers up and transmits! I was wondering what can be done to this radio. Also was wondering what kind of transistors it should have and what they are capable of. I figure it will make a nice radio!! 8) Thanks!!!!

Cheech,From what I am told you can do a lot of mods to that 146gtl.
I will be listening for you today.

Maybe you help me find out what is wrong with my 146. I've been testing lots of things on there. I just need an equilivent model to make sure that I am getting power where I am supposed to.

i just picked up a president ar144 ( same board as 146gtl ) from a pile of old radios in my buddies shed, its missing the channel sellector knob but its never been repaired or even had a soldering iron in it from new and works 100%

Yeah I would be glad to help out! Just let me know what you need! As for my radio Im thinking a chanel mod would be nice!

hey There...

Nice find indeed...
i used to have that radio...it was the 1st mobil i had...
worked very well for me (untill a stepped up to the then AR-3500)

i talked all over with mine in the early and mid 80's..

i understand it is very simular to the 148 i was told was same board but those 148's never had the audio my 146 did..

you can mod it for channels and a bit with power as well

Good luck with it


Later

Yeah I thought it was a good find! I was excited when it fired up!!!!!!!!!!!!!!!!!!!

I have 2 radios that are similar to the Cobra 146gtl. 1 is a Uniden AX-144 and the other is a Pearce Simpson Super Cheetah.
What i would love to know is, does anybody have any decent swing mods for these radios? I have tweaked and tweaked and the most i can get out of them is 2 watt dk swinging to 3 watts AM on my Bird 43. Anymore than 2 watt deadkey and she swings backward. SSB power is fine, i just can't get it to swing on AM. I have searched and searched the net with no luck.
Can anyone out there help this poor miserable mudduck from the bottom side?????

 

[Cheech]

What about the 1969 final mod for that radio? It would make one kick but! I had a radio that did 39 watts with the 1969. One cool mod in my opinion!

Modulation VR5 or CUT TR29.... Power VR10, (ssb)VR6 (Clarifier modification: Cobra 146 & AR-144) (1) Lift anode of D-30 and connect a 5.6 uH choke in series.
(2) Cut D-32.
(3) Cut both traces on the PCB going to the clarifier .
(4) Solder one wire to PCB ground.
5) Solder a wire from the other cut trace to an 8 VDC source
(note: 8 volts can be found on the cathode of D-50)
(6)This should give you 5 kc of slide.If more slide is wanted then change D-30 to a super slide doide.

Cool thanks for the info!!! 8)
