Hameg HM307 (1992)

Hameg

HM307
(1992)

10 MHz Oscilloscope with a small antenna is sensing a switching power supply running a computer monitor. This is a major noise source in my radio room, almost 200 mV P-P, OMG! My I put my 1/2 pence worth input. As a Radio Amateur, I measure signal levels in microvolts. To see this on my scope would mask any form of reception completely void. This image is a result of the only switching PSU in the shack, of a running DELL computer (19V. @ 4A.). The computer is well shielded in metal, the PSU is NOT. It's an external brick in PLASTIC. Three things that bug radio/audio (in no particular order): 1. Ground Loops 2. Unshielded Switching PSU 3. Unterminated Signal Lines
POWER ONE Linear Power Supplies (1995)

Superior Tube Tester

TV-11
(1964)

This is an emission type of tube tester, which some feel is inferior to the transconductance type of testers. However, if you are just trying to see if a tube is good or bad, then this one works for me.
