[Elecraft] How to Eliminate Power Supply Birdies?

2010-01-11 Thread Bob
I have an Alinco DM-330MVT power supply that has significant birdies on 160M. The power supply has a nice feature that allows you to move the birdies, which makes it obvious that the birdies are originating from the power supply. The birdies are at least 1 S-unit above the background noise.

One thing the other posters have not mentioned (probably not being SSB types) is a narrow filter for SSB. I have the 1.8 kHz 8-pole filter, and it is amazing. You do have to reduce the hi-cut a bit to center the voice in the narrower passband (an FC of 1.05 is about ideal for most male voices).

The RFI is almost certainly common-mode and is being radiated by the AC power cord -- and, by extension, the house AC wiring. Your typical store-bought AC line filter is a differential-mode device and will do nothing to abate common-mode currents. What you need is a common-mode choke on the AC

Switching supplies tend to have their worst noise problems on the low bands because those are the lower (stronger) harmonics of the switching frequency and the noise filtering tends to be less effective at low frequencies. It sounds like the spurs are coming out the power line. If the Alinco

On most radios, the term RF Gain is actually a misnomer. The control should really be called IF Gain. The way most HF receivers work is that turning down the RF Gain control simply applies a DC voltage to the receiver's AGC circuitry. For example, if an S9 signal causes the AGC voltage to rise

Re: [Elecraft] K3: RF Gain, Squelch

Phil, It is quite normal for the S-meter reading to increase when the RF gain is reduced. The AGC voltage (which drives the S-meter) is increased to reduce the gain of the receiver when the RF Gain is reduced - so the S-meter indication goes up. The way I tend to think of it is - there is

Al, To look at it another way - look at the S-meter to observe the band noise level, and then back off the RF gain until the S-meter is steady at that same S-meter reading. Of course, this should be done at a spot in the band where no signals are present. That is a quick way to determine the
