Re: [Elecraft] Slightly Unbalanced dipole?

One of the things that has been hinted at is the OCF dipole.  One of the really great attributes is that you can adjust the matching impedance of the antenna by moving the feed point away from center.  If you have a SWR of 1.5:1 and the R is 75 and the j is 0, move the feed point away from cente

Yes, the switching time in the amplifier is too slow,  hence you need to consider sequencing the amp keying so that it keys first then the KX3.  Sounds like the amp has a relay vs solid state switching.  Mel, K6KBE From: EA2BD via Elecraft To: elecraft@mailman.qth.net Sent: Thursday

Re: [Elecraft] K3 audio quality

Joe and all, Isn't this where the rubber hits the road?  That is while your EQ settings are OK  It does not address the audio spectrum generated by the speaker.  Consider a baritone against a soprano on the same settings.  I think we need to hear from Jim on how they adjust the mixer settin

Any of the older ones rated at less than 10 watt in and a linear version not Class C will be fine.  I have used the KLM, Mirage and TPL units with success on two meters with various rigs both FM and SSB.  There are quite a few on the used market, just make sure it still works as advertised for r

Re: [Elecraft] Sloping Terrain vs Feedline Losses

On a slightly different take, controlling the vertical pattern, ie minimizing the minor lobes, will have a significant effect on gain as the major lobe now gets all of the energy.  Elevated radials have more to do in establishing the actual TOA above ground.  This is not easy.  Try modelling the

Re: [Elecraft] Sloping Terrain vs Feedline Losses

Elevated radials will do more by establishing a fixed array configuration on match and pattern.  The orientation of the ground is another issue but with a fixed orientation the pattern will be more subtle.  I run multiple antennas with vertical orientation and find that the ground conductivity h
