MARKO Excalibur MK-2 AM/FM/SSDE

Hi can someone help me out here with this i want to remove the below from the radio also can someone tell me the values of the RV5 RV10 AND RV9




CB Radio

What does it do ?.
I would just take the top section off as it looks to have a joint.
Had the same radio back in the 80s would love another just to go on my nostalgia shelf.
The one i had i did the mod to put super low to super high in and built the radio into an old tv cabinet.

can can not use the radio if its taken out i loose all channele left with only 6...i would like the mod how to install it so i can remove it from the radio and put back to thr basic..thenk you for your hep too

Is it connected to that shaft in pic 3 ?.
If it is take the bolt out or is it not what i see.

Looking again is it a band select.
Should be fitted where the A/B switch it.
Need someone with patience to relocate it i think.

no they dont go to the a and b knob



here are the pictures mate

Is it a band select knob ?.
What i meant was  if it was then it should have been fitted in place of theA/B knob.

yes mate its a total "fluff" up the want to be rip doc knows nothing mate for the money i payed for it im not very pleased

Hi Ian,

Firstly, I've edited your posting to comply with the forum rules regards the use of inappropriate language so if we can keep it to a PG-13 level that would be fine.

It looks like someone has installed a band switching arrangement to swap out the mixing crystal for the Phase Locked Loop. Not the most elegant solution I've ever seen but that's pretty much what it is to give you extra channels. (Believe you me I've seen worse!)

As regards your initial enquiry regarding component values the following link provides a schematic/circuit diagram that may be of assistance :-

It looks like the board is the same as yours so may prove useful.


It seems like a fair bit of work is going to be required to bring it back to original condition but unfortunately that seems to be the nature of the beast with a lot of these older radios.
(Twiddle, twiddle. )

I can only wish you good luck with it all.


All the best,
Victor

What does the A/B knob do now anything.
When i had mine i changed the A/B for a 6 position switch/selector.
I would spend a few hours re-posioning that one on the top to where the A/B one is

Is it working again now.
Back to the 80 channels.

do not know as its not powering up
