Re: [Elecraft] HI RFI Message - what to do?

I like Bill's answer for a fixed multi-station setup.  Not good enough for a roughly controlled enviornment of FD. Or when a friend drives up to your house running a KW mobile. I think the bottom line is what the receiver front end was designed to handle and how much head room there is from

An old thought.  When trying to get heat out, one usually gets dirt, bugs, etc. in.  I like cranking up the AC and leave well enough alone.  Of course there is always the freon bath, not. Mel, K6KBE --- On Fri, 5/15/09, drewko drew...@verizon.net wrote: From: drewko drew...@verizon.net

Re: [Elecraft] Can a 1N4007 Be an Effective Relay Snubber?

2009-04-08 Thread Mel Farrer
Hi, I have used the diode snubber in all designs of relay control from small reed to large contactors.  I usually check the series resistance of the relay and the non solid state device activation and measure the voltage kick.  I then use ohms law to determine the peak current that would occur

2009-03-02 Thread Mel Farrer
Doing critical audio tests can be very demanding.  Circulating currents and non common ground loops are particularly a problem.  I have had to use a TOPAZ Ultra isolation line noise suppressor transformer to supply AC to both the UUT and the scope/spectrum analyser.  This forces the ground

I agree with Guy.  Now on the speakers, I have found matching pair of speakers at a swap meet that were from a computer store.  Same height as the K3 on legs and I painted them the same, or close color. Mel --- On Sun, 1/4/09, Bill NY9H n...@arrl.net wrote: From: Bill NY9H n...@arrl.net

I would like to add a comment on removing solder from SMT via holes.  There are three methods and the first two have been discussed.  I have found as the technology gets better, smaller, the plated through holes also get really small.  Like 0.020 or smaller.  Solder suckers have a very

Hi all,  I am from the old school of thinking that sometime I am going to need to key an AC relay in an amplifier and prefer to make a VERY simple interface and generate a set of dry contacts.  That way regardless of the keying gender, you are safe.  It keeps ground current loops out of the
