[Elecraft] Strange things a happening

[Rob May]

Had the same symptoms when SA-1, the surge arrestor on input 1 went out.  There is an SA-2 on input 2.  Could tune the beam to 1.5:1 but the SWR would jump all over the place when I transmitted.  It's a through hole part, so it's easy to replace.  $3.30 at Mouser, part number is 871-N81-A350X.  Buy an extra.

> Well to start off a couple of days ago i loaded 3.77 into the radio.  Then i hooked a 10 db preamp into the line coming from the 6 meter beam to the radio into ANT 2.  Definitly brought up the noise level anyway.  No signals to hear but at least i know the preamp works.

> Tonight before the local 6 M ssb net i removed the preamp out of the line from ANT 2 to the 6 mtr beam.  Set up on 50.140 and hit the tune button.  WOW, SWR was high but tuner brought it down.  Watching the meter while talking didn't look good and the Hi SWR was flashing as i talked  First station i heard was weak and he's normally S-9 anyway.  Said i didn't sound good.  Well check connections, settings and anything else that caught my eye.  Nothing out of place.  Figuring that maybe i had inadvertently connected the FM antenna to the K3 es VS i reversed them.  Nope, that wasn't it.

> Well about the end of the net (i was supposed to be net control tonight) i took the 6 mtr beam off of ANT 2 and put it on ANT-1  Boy did that make a difference.  Seems that the problem is with ANT 2.  Radio works fine on ANT-1.  I haven't taken the cover off this radio in 8 months, since i bought it so i've not disturbed anything inside.  I don't have the "AUX" connector.

> I guess the question is "why would the 6 meter band work fine on ANT-1 but not ANT-2 all of a sudden?  Without tearing the radio apart i ask this question of those noble folks with great knowledge.
