Hello All,
1) Good points Raj - Richard check voltages during RX on R18 and R38. See the picture below. Supply voltage for two RX chains is coming "from the top". Voltage drop on R18 and R38 is around 0.4V. Please check this drop. This will give us some overview of current consumption by each RX chain:
?
2) Additionally You can check voltages on transistors of these RX chain in relation to GND (I have marked these transistors with red rectangles on above picture with pinout):
?
3) Search also for cold soldering, cracked capacitors, other irregularities in this area. Could You send us photo of this area?
?
My measurements were done at 7100kHz LSB with 50 ohm load on antenna connector.
?
Regards
Tomasz
