Re: k3 receiver issues

Lou Kolb
 

Thanks, guys, for all the suggestions. I have two antennas here, a
G5RV and a vertical for 2 and 440. The problem is present no matter
which antenna is inline. Both instalations are only a month old, both
using the Andrew equivalent to LMR400 with new, well protected
connectors. That's why I suspect the radio, but I'll look into
everything. Lou WA3MIX

Turns out it was a corroded guy wire... The guy was corroding at the
point where it was connected to the guy anchor. Years ago he had buried
it in his garden, and it had corroded.

We located it, fixed it, and it never happened again... Moral of the
story: It might not be just coax.

Lou,

I had something like that not long ago. It was a corroded coax
connection outside my house. RX was OK for a while after a short
transmit but problem was still there after a few minutes.
So check that first before digging into the K3.

If you are hearing harmonics and or intermodulation products of broadcast signals then the most probable cause is a corroded connection in your antenna or coax feeder.

When you transmit the signal amplitude is so large that it overcomes the corrosion.

Greetings all,

For ten years now, I have thoroughly enjoyed owning and using K3-100
SN-4290. Along the way, I've upgraded the synth board (only one
receiver) and added the general coverage filter. Things have worked
flawlessly until recently I'm hearing what sounds like a loose
connection somewhere in the receive path. signals and atmospheric
noise are jumping up and down, as if something is not making proper or
consistent contact. This happens regardless of what antenna is
connected. I'm saying "receive signal path", because, by all accounts,
my transmitted signal is rock solid. Other than normal QSB, no one is
hearing the slightest variation on it's strength but the signal I'm
receiving is varying wildly and randomly. The base audio noise in the
rig does not seem to change at all, just signals from the outside. I'm
also hearing some broadcast images that come and go as the signals
vary. any suggestions on which boards I should clean or reseat would
be appreciated. I've never had my hands inside the radio and I'm just
a bit timid. Lou WA3MIX

Thanks Drew.  It makes it more efficient to know if it is a post of interest.  I appreciate the very useful information provided by members of this group.

Please - use good thread manners and keep things on topic.  Lots of people read these things and this reflector has a fairly poor signal to noise ratio.

Wherever your from, you should proud of it. I was lucky enough to be born in Texas. 

Some might say unlucky. I could never leave although I'd like a cooler less humid climate. 

I'm sure there are a few in California feel the same.

Elecraft's latest post on Shelter-in-Place answers the question in the thread subject.

Re: KPA 1500 Minimum Ambient Room Temperature

I suspect my temps in the area where the amp is located may dip into low teens come winter time.   I guess I will just monitor it and see how it goes.

Thanks for the input from VP8PJ and good work there, Gene

Gene,

(Small rabbit trail)

And a GREAT showing that trip made!  Thanks for the many contacts (21 confirmed), the treats were on 160M (500 watts, inverted L) and the shocker was on 60M (100 watts into a rotating dipole, WOW!), so shocking I tried it again successfully a couple nights later. 

Elecraft to Elecraft, it was almost easy; you clearly heard VERY VERY well there.

Thank you!  WELL done!

Later this week, I'll finish moving pieces into the new shack and KPA1500 s/n 012X will finally be heard on the air (two years after arrival).  Then I can pay attention to fan noise and temps and join in those conversations with my data.

Thanks to Elecraft's generosity, we had a KPA-1500 on the recently completed VP8PJ South Orkney DXpedition. The temperature in the operating tent was usually in the low to mid 30s(f)  (0c to +3c) all the time.
 
Even after 13+ days of DXpedition operation the RF deck and power supply remained surprisingly cool to the touch. During my shifts using the 1500 I don't recall it kicking into a higher fan speed. Possible I didn't hear it because of the generator noise and headset. We typically ran 800 - 1,200 watts out, the amp ran flawlessly.  The usual DXpedition "accidents" didn't bother the 1500.
