Re: [Elecraft] Low activity

I posted the question, "What is the BEST antenna to use with my K???" as a "tongue-in-cheek" question to see if it would generate some activity, and it was wildly successful.  I posted it at about 12:30pm PDT and it is now almost 5pm PDT.  There are over a dozen responses, and at least two

Gene, I don't usually comment on products like antennas.  I cannot, however, resist this one: I cannot comment on the current Alpha Antenna Mag Loop, because I don't have one.  My Alpha loop is 4 or 5 years old.  It was on sale and heavily discounted, so I purchased it without looking into

Re: [Elecraft] Best Batteries for KX-3?

First, and most important, don't leave alkaline cells in your radio for long periods.  They will eventually leak.  If you have the KXBC3 installed, I suggest high quality Low Self Discharge (LSD) NiMh cells such as Eneloops,  If you don't have the KXBC3 installed, non-rechargeable Lithium

Re: [Elecraft] Can I overcharge the batteries in my KX3

First of all, forget the Nicads.  The KX3 isn't really designed for Nicads, and they have a lot of problems such as excessive self discharge, and leakage.  If you want rechargeable cells, use modern low self discharge (LSD) nickle-metal hydride (NiMH) cells.  Eneloops are one example, and

I think a pipe with a speaker in the end is considered a closed end cylinder, but I am not completely sure.  If so, resonant lengths are shorter.  Here is the page from one of my favorite websites if you are interested in experimenting with resonant speakers:

In the late 70's, I used a Sky Tec CW-1 resonant speaker.  $9.95 USD in 1977.   It worked very well and had a very sweet sound.  A sleeve in the top allowed pitch adjustment.  I still have it, somewhere around here... When I first got my KX3, I considered duplicating it (it is made primarily
