Hi All
In preparation for delivery of K3 in the winter, are there any suggestions for
a PSU (available from a supplier in the UK) capable capable of running the 100w
version of the rig?
Cheers

Don:
Kenwood 930, 940 and 870 derive the 8830 KHz IF output port from a
dedicated mixer that duplicates the main mixer, but without the roofing
filter, if I recall the schematic correctly. Hence there are parallel
signal paths, one for the main signal and a second path for the IF sample.

Hi Paul,
How about a MyDEL MP-925? I have one as GD4ELI, I like it.

As a collector of photographs (good Daguerreotypes

more folks here would prefer doing them.
You can easily draw an analogy between electronic

Hi John,
One more factor to consider is the question of how you are measuring your
output power. If you are using the KX1's display you need to remember that the
power out shown there is dependent on the match that you have with your
antenna. A mismatch produces a higher power out value than

Does the K3 have a non-programmable boot loader that cannot be

It's possible that we'll rewrite the K3 Downloader software application
in VB6, etc., so that .NET won't be needed. The only reason we use .NET
now is that I'm a C programmer, and the quickest way for me to get the
downloader working was to use Microsoft's C# programming environment.
Correction - elegant not elegent. ;-)
And not elegant in the manner of the .NET Framework
which is typical MS bloat, but with respect to VB or
C# code which is clear and concise. That's why it
should be a very good port.!!

Wayne,
Given a choice, I'd leave it in C#, since with the existence of .NET
compatible libraries on alternative OS's, you'll have a better chance to
encourage people that Elecraft cares about giving people a choice of how

The most likely reason is that your filters are currently not set
correctly for single signal reception and allows the BFO to leak some
signal into the IF passband.
I suggest you wait until you have all bands working and after you have
