[Elecraft] Antenna tuning or matching unit

This all depends on what is meant by antenna tuning. When teaching newbies the wrong phrase can cause problems that are not seen till later. Antennas are tuned with wire cutters or a hacksaw so the feed impedance is the desired value, ideally 50 ohm resistive or at least a match for the feeder

Re: [Elecraft] K3 with N1MM - SPLIT mode

Hi Ted, All of the stations that I clicked on the bandmap were operating transceiver. After a while I was paying more attention to the issue. I think I only worked one station that was split. I had never seen this happen before. For ARRL SSB will swap K3's to see if the problem is still there.

Re: [Elecraft] Antenna tuning or matching unit

Then there are those of us who use high ratio end fed half waves for specific frequencies with great luck. I do this on 160 for 1.900 coverage. This allows me to deviate marginally from that frequency with a matching unit. Works great near 3.8 as well. Now to get it further into the trees.

Re: [Elecraft] K3 with N1MM - SPLIT mode

I think what counts is not the way the target station is operating but rather the way the spotter station is operating. If the spotter had Split engaged, for example to dither its calling frequency in order to stand out in the pileup, then the spot may specify split and cause your symptom, even

Re: [Elecraft] K3 with N1MM - SPLIT mode

Ralph, That is interesting. I had assumed the listed calls were transceiver. But I would sometimes have 3-5 in a row from the bandmap that went into split mode. Will pay more attention to it in ARRL SSB 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net

Re: [Elecraft] Antenna tuning or matching unit

Alan your explanation opens the door to erroneous conclusions. Frequently a feed line does NOT have a low SWR by design. It is still a feed line in that it carries RF from the transmitter site to the radiator with a minimum of radiation from itself. A classic example is the Zepp antenna: a 1/2

Re: [Elecraft] Antenna tuning or matching unit

I agree with Ron in that one must understand using an ATU at the transmitter does not change feedline loss. In fact it adds additional system loss due to loss incurred in the tuner. If the transmitter can not deliver rated power into the load that is a different issue to resolve. The ATU may

[Elecraft] Mac Clock Question

Before I get into the list of problems I’m having using WSJT-X FT8 on my K3S, I’d like to know: 1. Is the automatic clock setting in my Mac mini (running Sierra, 10.12) good enough for modes like JT65 and FT8? 2. If not, what’s a good reliable time sync app I can download and use? Cheers!

Re: [Elecraft] Mac Clock Question

My general thought on computer time accuracy..start decoding stations.   Watch the DT value of those decoded.  I find if the majority are less than <0.5 +/- then your computer clock is good.   If most stations decodes  are greater than >0.5 +/-, then I'd look for a better time reference.
