A friend in GI (Northern Ireland) wants to order the Flexradio. I fear
he is making a mistake and feel the urge to share my conviction. Is
there a lucky K3 owner in the Belfast area? Has someone tested both

I'd just like to make the list aware of a bug that 2 of us have encountered
in the latest firmware (MCU 1.65 or 1.66 and DSP 1.52).
I understand this was fixed previously and has crept back into the codeline.
Elecraft are aware and working to resolve it.

Hi guys,
On 40 the band is very busy over here in Europe. Since my CW skills
are not the best, a good filter makes it easier for me to decode
Morse in a crowded band. Now I have a 400 8 pole and I think a 200 Hz
5 pole or 250 Hz 8 pole will improve the rx and possibly take some
workload
Gentlemen,
I do not think this program is a bad idea and not withstanding comments
from the cw purists, it could actually increase the number and
proficiency of cw operators. When I was just starting out and struggling
with 22 wpm, contesters running at 35+wpm just blew me away. I recall
Hi,
I have a gradually worsening problem on my K2 when I try to select
PREamp, ATT, or normal. The symptoms are the relay clicks (normally)
but on the PRE-ON and ATT positions I get attenuation levels on RX. In
Normal mode I get a very deaf K2. Sometimes the only fix is to

I could use one too. I have an XV50 which I may convert to an XV144 as I only
need enough power to drive a transverter. If you do not find an XV144, why
not convert your XV50 to 144 MHz? If you can build one you can rebuild one.

Being able to choose and set a tuning power level (not for internal) for

I know that sequencing of Rigs and Amps has been an issue with many brands of
radios. As I am researching the features of the K3, I did not see any

I agree with this 100%. I suspect that the only reason Elecraft is
offering the 8-pole filters is that it is easier just to let people buy
them than to try to explain why they don't need them. :=)

probably can't tell the difference between 2.6 and 2.7 so it's no real
hardship to keep the DSP 100z narrower, but it's a bit of a niggle.
It's rather simple - above 2kHz the K3 uses 200Hz steps and below 2kHz
steps of 100Hz.
If you tune down from 2.7kHz: 2700, 2500, 2300, 2100, etc.
