Radio Make and Model: intek497 (dragon ss-497)
PCB Number: n.c
PLL Number: n.c
Symptoms:
When the RTX is in RX state, i see the signal at +4db and more
on s-meter only if i receive a strong signal.
But for the less +4db signal, i see 0db on s-meter..leaving open
clockwise RF-Gain .
What is working:
rx and tx area working correctly
What has been tried:
1- the RTX is aligned on TX and RX, using a professional Rf-Generator
like Marconi-2022.
2- The audio is not distorced.
3- i have already checked all diodes around BA72B (ic) and Q6, Q11,
Q24, Q7..this transistors area is ok.
4- I have also checked around RX
between Q80 to Q15, seems all ok.
Did it suddenly happen ?:
it's a 2nd hand RTX.
Anything else that may be of help?:
everybody

ps. sorry for my not strong english.
