Re: Very Quite audio, TR396FCC

mate , i've had problems like this on an 858 chassis. Check the electrolitics ( caps ) feeding the input of the audio chip. I had one problem where the cap was open curcuit.
Infact , just replace the caps around the audio amp.
Hope it works for you.

Re: Audio 'gargle'

perhaps you might want to "juggle" the vco can. Slightly tune it on the band that you're having problems with.

Re: Uk fm motorboating on high channels while on tx

Gday Mate , sounds like the vco is not locking. Get the service diagram and re-align the vco and asscociated cans.
Good luck !

If I place a finger around chip there IS a hum. Squelch works ( you can hear it faintly going off and on via the speaker ). PA works. The board...

Re: 352D

Hi, did you manage to sort out the problem? I"ve got the same thing here - the radio is near spotless and I'd like to get it going. RX is fine after a tune up and realignment of PLL to lock it up. TX works, OK on AM full carier, but low mod almost non existant. SSB is working, but again very low mo...

Hi matey...try this... The AM regulator 2SC1419 is WEAK. UNSOLDER it and toss it in the trash. Replace it with a GE-66, ECG-152 or a NTE-152. Relay buzzes on SSB, no am transmit, lights go dim, or the fuse pops sometimes? Replace C179 ( a 2.2uF 25v tantalum cap located near finals) with a standard 2...

Hi Matey.
This might sound silly but it does work on Philips radios....Have you tried earthing the mic ? OR have you tried placing a magnet on the back of the mic ?

Hello again.

Go to this website and click on ranger / or superstar etc and follow the cuircut layout.
The name may be different but youll find that many radios are identical inside.

Hi matey. This might and I say MIGHT be of some use to you... November Tech Tip on the Month: RCI-2980: In some units, you may notice that the frequency will drift when the unit gets warm. This is caused by the "KIA6410S" IC's installed in place of "TA7310P" for IC8 and IC10. To correct this driftin...
