Re: [Elecraft] Slighty off topic - 80 meter second harmnic how to stop

When I lived in California I had a 80/160m inverted L in which the horizontal part passed over the house. There were alarm wires running through the attic, and when I first tried it I actually vaporized a terminating resistor at one of the windows. Those wires were quite long and possibly

Several people offered some very good suggestions and asked several valid questions about my testing. Here are answers to many of those questions: 1. The meter I'm using in the test is a known-good MFJ-815B HF power/SWR meter. 2. I'm using a known-good 300W dummy load for my "antenna", so any

Re: [Elecraft] Diversity Mode filter selection question

In the filter configurations the filter lineup and width definitions must be identical or you will get state changes in the main and sub RX that do not happen at the same time in diversity. If the filter offsets are incorrect you can get a similar effect. 73, Guy K2AV On Tuesday, February 23,

[Elecraft] Diversity Mode filter selection question

I'm the proud owner of four K3 radios at my contest station and one of my new K3 (89XX) is doing something different than the other three and I'm trying to understand what it's doing. In the diversity mode as I change the width control and reach the selection points for different CW filters to

Re: [Elecraft] K3 unable to change passband control shift amount in SSB

Setting to “NOR” by a long press on Shift control should reset the passband, if having it off center is what’s causing your issue. Full disclosure, I don’t use SHIFT/WIDTH on SSB, so switching between the two modes is not something I’ve done since building the radio in 2008 :-) Grant NQ5T K3

Re: [Elecraft] and now something completely different.. the w2

1. Not possible. The two sensors feed into an electronic switch that connects one sensor at a time to the microprocessor/LED bargraph display. 2. See the "W2 Owners Manual Rev D2", available on the Elecraft website. On page 5, "Important note" #5, it describes how to put the W2 into "search"

I would expect that if it was getting into an alarm system, the alarm would fail in some way. I had a bad problem with mine, cured by a 5th order 200 kHz lowpass filter where simple ferrites and caps did not work. The alarm system has low frequency digital data. I built it with some caps and a few
