Lyn,

Having lived in Northern Calif and now in Colorado the propagation from further west than Illinois where you live, is a big factor.

Nevertheless, there are mysteries in 160M propagation.  A friend (SK) who lived here, K9BWI had around 300 countries on 160M from Colorado and the rest of us wondered why--a 50ft shunt fed tower in a city neighborhood.  We have various conjectures on why, mine is the grounding of his house, being that soil conductivity is very poor here, others are "golden ears", an exceptional operator (worth many S units).

Another example is W0ZV (now W4ZV) who worked many countries on 160M from Colorado years ago.  When I saw his antenna the explanation was clear:  a 160ft tower with a cage radiator and 32 elevated radials, a rural (quiet) location on top of a small hill.  This guy was not only a really good engineer but an exceptional operator as well.

Not being an expert on 160M propagation, I'd guess that the path from W6 to EU going through the auroral zone is an additional challenge.

Chuck K0MV

I figured it would be an impressive assortment of 160m antennas, and you don't disappoint. With all that going for you, there must be something else holding back 160 at your location (terrain? ground conductivity? bad connection somewhere?). I say that because you mention needing to run full legal power on 160 to work EU.

You'd probably laugh at my 160 setup, but basically it's a simple 5/8 wave dipole (360 feet E-W with max sig N-S) center fed with 600 ohm ladder line (160 feet) with all the appropriate impedance matching, choke, etc. I seldom run more than 50 watts (can go to 500 if needed, but hardly ever do on any band). Yet in 2 short years, I have made over 4,000 contacts on 160 including 61 DXCC entities and separately, WAS in a long weekend. I generally receive better sig reports than I give. And as you know, I am dead center in the dreaded "Black Hole" of DX.

Maybe all those redwoods are a factor? Or ground conductivity?

Hi Len,

I have three for TX. The first, a Tee with the top supported to about
100 ft between two redwoods, with about 60 on-ground radials; the other
two are wires sloping to the east and to the west from the 120 ft tower
that holds my straight 3-el SteppIR, 30 ft long 6M Yagi, and feedpoint
for 40M wire Yagi. The wires are insulated from the tower, and fed, one
at a time, from the base against 4 radials elevated about 20 ft. The
tower acts as a passive reflector. The tower also acts as a reflector
for the Tee to the south. The tower has 8-10 on-ground radials

For RX, I have two reversible Beverages using DX Eng hardware, 550 ft to
EU/VK, and 500 ft to SA/JA. And I have a pair of VE3DO loops spaced 5/8
wave and aimed at EU, that I can steer +/- 30 degrees with a DX Eng NCC-1.

There's something wrong with the two sloping wires that I need to fix
during the summer. It's got directivity, but negative gain, so I suspect
something with the connection of the tower's radial system.

Yes, the KAT500 matches that antenna 160M - 6M. Although I do have resonant antennas for other bands. Those are all coax fed. Yagi for 6M fed with hard-line.

Search the manual for EE INIT.  Before anything, it's best to use the K3 Utility program and save your current configuration.  After that make sure you have the latest firmware installed.

Re: KAT500 CONFIGURATION QUESTION

Mike Flowers
 

Hi Russ,

For some unknown reason, my installation of the KAT500 Utility requires that I ‘Run as Administrator’ to have it function properly. 

Something is amiss in the labyrinthtine Windows security scheme.   Elecraft support wasn’t able to help me fix it, so I just run as administrator. 

You might give that a try - worth a shot.

WTB: KRX3A Sub Receiver

Ken WR7D
 

Looking for a KRX3A sub receiver for my K3S. With or without filters is OK. Would also consider a radio that has the sub receiver installed. If a K3, it would need to have the upgraded KSYN3A synthesizer.

I know Elecraft is considering making more of these, but not sure when or if that will happen. If they do, it will still be several months.

Thanks

Here's an example of the product I'm describing, but there are many similar products available:
 
Hopefully this, and the other advice about time synchronization will get you on your way.  I agree that using an external USB sound card might give you greater dynamic range (if you buy the right one), but I kind of favor the Y cable approach because it is simpler/lower tech.

Re: K3 power adjustment

Dave (NK7Z)
 

Wes,

That is a gross misrepresentation of what Rick said, but even though it is misrepresented, it can serve to make my point...

Here is an example-- Using the radio as you describe, will, not might, but will, tick off every local person around you on the same frequency, be they Digital, or SSB.

So yes in some cases, you might be transmitting power to the antenna. Every fan, noise, and pop in your shack will be transmitted and all of your Amateur neighbors will have to put up with it.

Here is a real world example-- I have a ham neighbor who somehow manages to get enough noise into his transmitted audio stream, that when he keys down, I see a pedestal of noise from his rig, 3 to 6 db in height, (sometimes more), and as wide as the passband of the transmitter, with an audio signal spike somewhere on that pedestal which is the FT signal.

So for me, while he is transmitting, I lose 3 to 6 db of signal across the entire FT bandpass for every station transmitting at the same time he is. When he drops audio, for about 1 second I see a noise pedestal with no audio spike, (FT audio), as his VOX holds the transmitter keyed. For him, he looses 3 to 6 db of signal to all stations he is transmitting to...

So in reality, a radio run as you describe will be transmitting RF, and all of your local friends will be forced to listen to it if you are on a net. If conditions are right, others on the FT band may be forced to listen as well.

The problem with using the software slider in WSJT-X is that it's

the Elecraft line with the power set at 100 watts; the radio will
'hunt' in it's attempt to produce the 100 watts.
In that hunt, any other audio within that loop will be transmitted;
meaning that while you are making contacts, you're also likely
transmitting products other than the JT tones.  That other audio is
likely causing issues for others in the band.
A responsible operator wants the cleanest output possible to both
focus the energy in the wanted spectrum and also to be a good
spectrum neighbor (stay within the lines, don't add noise).
Having the correct audio drive (4 bars lit, 5th barely tickled) and
using the RF output power control on the K3, is the proper way to
manage RF output to meet those goals.  It is the responsible way and
helps to keep the noise down.
