Hi all..im new here and im also coming from the Netherlands ( Europe)...so please forgive me when i write something wrong in english.
I have here a Stalker XX main board PC-411AD with the MB8719 PLL inside.
I can recieve on ALL modes but cant transmit. RX led is switching of when i push the talk button but TX is not switching on. So its also not transmitting.
I need a technical manual or a copy( digital) so i can fix this old radio.
i have searched well on internet and its hard to find something about this radio.
Can somebody help me here ?
Best regards ...

Re: Stalker XX on TX.
It sounds like IC4 (MB3756) has failed, check the voltage on pin 1 it should be about 7.5 to 8 volt in TX if not replace IC4 but first check that in TX pin 5 low to about .5 to 1 vdc if not check mic wiring.

Re: Stalker XX on TX.
Did you fix the problem, if so what was the fault, as it may help someone else.
