IC 7300 VS FT 902DM internal noise and receiver noise settings
This video shows the difference in internal noise generated by the IC-7300 and the FT-902DM as well as the ineffectiveness of the RF gain and the attenuator in the IC-7300 to reduce this noise. It also shows, what are the best settings for the IC-7300 for minimum internal noise.

Fixing and modifying the Tektronix 491 IF attenuator for external use - part 1
มุมมอง 59หลายเดือนก่อน
In this video, I am using the IF attenuator of the Tektronix 491 as an external general purpose module. I find the issues with the badly drifted resistors, I replace them and finally fix the attenuator. Make sure you watch the other parts of the video. Check out also my main website at qrp.gr
