[Elecraft] Antenna 2

My K3S's only have one antenna port so I maybe I do not understand the issue. Why are you grounding it? John KK9A Paul Ormandy paulzl4tt at gmail.com Tue Nov 28 17:52:08 EST 2017 Previous message: [Elecraft] Contests Next message: [Elecraft] Antenna 2 Messages sorted by: [ date ] [ thread

Re: [Elecraft] Antenna 2

Either put a small 50 ohm load or leave it open. A short to ground may cause a PA device failure. Bob, K4TAX Sent from my iPhone > On Nov 28, 2017, at 5:19 PM, Jim Rhodes wrote: > > Well if you accidentally transmit into it an open might be better than a > short. Did

Re: [Elecraft] Antenna 2

Well if you accidentally transmit into it an open might be better than a short. Did you at least disable it using the utility program? Jim Rhodes K0XU On Nov 28, 2017 16:52, "Paul Ormandy" wrote: > Thanks for the replies. Hadn't thought of its use for sub rx or dummy load.

Thanks for the replies. Hadn't thought of its use for sub rx or dummy load. I have grounded out the connector with a plug hooked directly to the receiver grounding terminal. Paul __ Elecraft mailing list Home:

I have my Antenna 2 jack permanently connected to the input of my K3 2nd receiver, which normally is parked on 6M. The Antenna 2 jack is permanently connected to a 6M vertical, allowing me to be aware of any 6M openings while going about the my usual HF operatings. FWIW ... 73! Ken Kopp - K0PP

Re: [Elecraft] Antenna 2

I believe he is actually operating into an antenna on Ant1 port. He switched to Ant2 to check the port isolation and would obviously switch back to Ant1 to operate.  I doubt grounding the non-selected antenna port would make any difference on TX and some use both ports for diversity RX.  If

Re: [Elecraft] Antenna 2

That doesn't explain how he expects the rig to short out the port for Ant 2 . .. WHEN IT HAS BEEN SELECTED ... just because there is no actual antenna connected to it.  I don't get the reasoning behind the original query. Dave   AB7E On 11/28/2017 7:04 AM, K9ZTV wrote: We hook dummy

Re: [Elecraft] Antenna 2

We hook dummy loads to ANT 2 on all our K3s during FD to prevent inadvertent transmissions when no antenna is connected to it. The ATU TUNE button is immediately above the ANT button and fat-fingered/far-sighted ops unfamiliar with the K3 have been known to hit the wrong one, especially on

Re: [Elecraft] Antenna 2

I keep my dummy load connected to ANT 2 on my KXPA100. Might as well have it connected somewhere. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 28, 2017, at 6:22 AM, Don Wilhelm wrote: > > Paul, > > There is some stray

Re: [Elecraft] Antenna 2

Paul, There is some stray coupling between ANT1 and ANT2, but no direct path. The unused antenna is not grounded. One reason is that it can be used to feed the subRX AUX ANT input when using diversity. 73, Don W3FPR On 11/28/2017 2:36 AM, Paul Ormandy wrote: Hi all,     When messing

Re: [Elecraft] Antenna 2

If you do not have anything on Ant 2 I suggest using the config utility to disable Ant 2 for now. This will prevent accidentally selecting Ant 2 and trying to transmit. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft

Re: [Elecraft] Antenna 2

If you selected Ant 2 it wouldn't have been "unused".   How is the rig supposed to know you don't have anything physically connected to that port? Dave   AB7E On 11/28/2017 12:36 AM, Paul Ormandy wrote: Hi all,     When messing around today with antennas, I had my aerial connected only

[Elecraft] Antenna 2

Hi all,  When messing around today with antennas, I had my aerial connected only to Ant 1 and discovered that when selected, Ant 2 was capable of receiving signals with no antenna connected to it, albeit at a much reduced signal. I would have thought the unused port would have
