My K2 (2016) is suffering low output starting on 20 and wrapping around to
10 and 160 where I get little to no output. 80,40,30 are unaffected. Rx is
great. Symptoms include, low output and inability to increase output beyond
a certain level. Both symptons vary per band. When I'm less tired I'll
Hi Steve,
1. will the T1 tuner ever be made available as a bare
board? (as in, no enclosure)
No. Eliminating it wouldn't reduce the price much, and the case holds
all the pieces together nicely without any extra hardware.

You have a definite problem in the PLL Circuits. The PLL Circuits are on
the schematic of the RF Board Page 1 of 4 and is everything on the top half
of the page.
You need to check all the componets in the PLL circuit. It appears that the
PLL is unlocked in all but three bands. Any re

I hold the minority view that 150 kHz span (you'll actually get closer to 180
kHz) works just fine. The tuning is pretty linear at about 18 kHz per turn
across the entire tuning

The Buddipole antennas are very good for what they are. It is helpful to
have the mechanical parts to run them either as verticals or horizontals.
They are well thought out, and durable. The workmanship is top notch.
They come in a variety of versions for traveling needs.

SM0RVV, Erik has it right. Starting at 0.70 on
most bands you are fighting the digital modes anyway.
I actually wouldn't mind a mod to make the total
spread variable. I am very rarely above 0.25 on
any of the bands. That way you could switch to
25kHz (example) total and have some real fine tuning.
Hi All,
Maybe my emails were not getting through.
R11 and R30 mods in the KX-1 will increase output power but won't do
amything for low transmitter power on 20M (etc).
R11 can be changed to 3.3-5.6 ohms and R30 can be changed to 27-33 Ohms
but do not exceed 33 ohms. I have this from Elecraft. Aft

I first built it with 150 kHz, but changed to 80 after a few weeks.

first use it after the K2, but after a few minutes it's a great compromis
Hi all: I have just completed all the alignment steps for my XV-50.
Everything seems absolutely normal, except that I have got max output power
on 6M of about 14 watts, with 5 watts in from my K-2. Peaking the
inductors, L12-L17 was a little "mushy" - the peaks are there, but not very
sharp.

I'm considering getting a K1, this question of 80 vs. 150 kHz VFO
tuning width is a bit disconcerting.
I'd like to set it up for 150, but worry that the rate will be too
fast, too fatiguing to use.

Must be a dark secret, Grif. Nobody seems to want to tell, apparently least of

where I usually operate. The volume never goes completely off wi

My guess on power variations would be:
1. Core/winding variations in the RF PA output inductors and capacitors
2. Variations in the DDS lowpass filter inductors/caps
3. Variations in freq response of Q4, Q5 or Q6
4. Bad Q6

I also read quite a bit about compressing L2 to 70% or so instead of 90%
for low power problems. Have not tried either, but compressing L2 seems
like a much easier task than swapping the resistors. I will try that
tonight and let people know how I fare.

Jeremy,
think of mechanical tolerance issues for a minute; let's say, a shaft
and a bearing for example; take 1/4 inch diameter, with some tolerance
and take the specifications; imagine the diameter specs are .250 inch,
but to make sure it fits, the hole in the bearing might be specified at
0
Why the difference, they are all the same rig why would it change from
rig to rig?

I live in an apartment and use the Buddipole as my only
antenna. I have all the parts necessary to make either
the standard dipoles or vertical.
All I can say is that it's fantastic. On 2 meters through
20 meters, it's a fantastic performer. On 30 and 40
