EP 152 - Midland 150M Classic AM CB radio - no audio fault , can i save it ?
2 Classic AM CB radio's on the bench , can i save them ?

I remember I had the 120ch Am/ Fm version of this radio ! Loved it , had the high band off set for UKs before we could get mod boards !

[@MicroChipz]

Thanks

That's some odd fault. Maybe it was caused by the flux they used back in the day in combination with moisture.
Nice little Radio anyway.
Is this a cybernet chassis?
Also a nice "little" hand held radio. 5W AM - that must be working fine! In Germany back in the day only 0,5W AM was alowed and AM was only alowed on ch 4-15
Greetings from Germany.

Think its Midlands own board , yeh possible flux and moisture corrosion , was a pain to find , but we did it and another classic radio saved , thanks for watching.

Nice radio and nice work finding fault... rare to see a faulty coil 😊

[@MicroChipz]

Thanks

That Midland was my first cb radio! Had one of those and a 100M

[@MicroChipz]

nice

Hiya mate another one saved that was a tricky fault but you got there nice little radio and I like that realistic one too
Auntie Mary I remember that very well keep up the good work

[@MicroChipz]

Thanks

I have one of these works brilliantly gave it a test a few weeks ago.

[@MicroChipz]

Yeh nice solid vintage radio

Those 455KHz and 10.7MHz IF Transformers are getting difficult to source, I have kept a collection over the years just in case. Good spot though, simple logical testing of each stage lead you to the actual fault, it's too easy to think it's a silicon issue. I wonder how difficult it would be add an FM board? I think Tony at Spectrum still sells the FM boards as a kit for not much money, and with your wizardry I'm sure you could swap the PLL and give it full coverage. Anyway, great video, really enjoyed it.
Cheers

Yeh I think a FM board would go in it , the pll swap could be tricky but not impossible , this pll uses different freqs for rx and tx , I did try with a ham Uk and didn’t get far , maybe il revisit one day,

[@M0XXQ]

@@MicroChipz I suppose another option would be to replace the PLL and VCO with an SI5351 and replace the LED display with a small OLED using a rotary encoder, pop the band selection on the encoder push switch. Anyway, have fun, looking forward to the next video.

Looks familiar lol

[@MicroChipz]

Might be ;)
