Its Mostly About The Receiver
Pulling in and Cleaning Up a Weak Signal
14
Not to Scale
1. Narrow your filters to reduce noise and reject interference
2. Shift your IF to reject adjacent signal interference and match
passband to desired signal characteristics
3. Try CW-R if a strong adjacent signal is interfering
4. Back off or increase noise reduction levels and settings
5. As you do steps 1-4, pay attention to desired signal
intelligibility, not levels of signals and noise
6. Try manual RF gain control (be careful, especially if wearing
headphones)
•
Back off RF gain until receiver is quiet, crank AF gain to max.
•
Slowly increase RF gain until desired signal just rises out of the noise
7. Try turning on the attenuator (especially in a crowded band
situation like a contest) and repeat the above steps
•
This may bring your rig into a more linear range of operation
