Ron,
Second that. I found it easier to maximize output by substituting a
1k resistor in series with a 1K pot for the 1.8 K resistor. Also after
connecting the battery backwards once, a diode in series with the +
supply was added.

This unit produces about S9 noise on most bands with a fresh battery.
Great for aligning filters.

Cdx are punk here in the Northwest today. Very few signals below 21 MHz.
If one of the little Elecraft sig gens is too pricy ($90 to $180), think
about assembling a little noise generator. I have one made out of a handful
of parts with the most expensive piece being the 9V battery. The late Tom
Hammond, N0SS, still has it on his web site:

There are a couple of other versions on the same page.
Once you note how your S-meter reacts to it on each band when the rig is
obviously working well you can use it to see if your rig has gone deaf
later.

Subject: Re: [Elecraft] K3S Radio check?
2.5 nothing band noise
5 nothing just band noise
10 signal S6.5 with lots of band noise but readable
15 S6.5~S7 readable and clear with band noise
20 S8.5 very strong with almost no noise
25 S9 solid tone of some kind, no other signal or sound evident.
I don't have the all band receive module if that matters..
I'm thinking everything is working and I just need better antennas.. ?
Thanks in advance.
