My I just add a vote in favour of a sturdy case for taking the W1 portable?
For the shack I have N8LP's offering, for portable I currently do not have a
solution and the W1 in a case would be ideal.

Hi Simon,
Good to have you join this vote. I have just finished the construction of
W1 and shall use it for portable use. I do need a case because W1 will be
used in the field. My LP100 is to be used in shack.
Since W1 now does not have a case, when my fingers accidentally touch the
Hi All,
I received a new 2 band ( 80 and 40M) board for my K1 and a NB.
The Saga starts:
I needed my eyes examined, I'm 64, and I have a lot of change in my lenses
prescriptions, plus have beginning of cataracts in left eye, which is my good
eye. Great to get old, LOL
So ordered a new
I'm looking at using this with the Small Wonder Labs 20m PSK transceiver and
Elecraft T1 (?) ATU (which I have already), thinking about a live demo for
the 2007 RSGB HF Convention. A simple and effective portable station coupled
with a nice 12.1 Toshiba laptop.
Without a case the W1 would get

Help:
I recently completed construction and alignment and test of the XV144. I
encountered no real problems with the build. I've had it running with my IC-781
as an IF for a couple of weeks. I have a couple of questions and some comments:

My K1 Serial 1491 with KFL1-4 also died on 20m for no apperant reason.
This happend only few weeks ago.
The K1 had been off air ( shame on me) for 2-3 months.
Arrived at my holiday QTH , unpacked and powered up the K1 and it wouldn't
tune on 20.
No rx noice when tuning the vfo over the band.

2 reasons for the use of 1N5711 diodes rather than 1N4148 (or even 1N34A) -
1) the 1N5711s have been shown to produce a more consistent voltage over the
frequency range than any of the others, and 2) the Shottky design has a low
diode drop (the 1N34A does too) which will produce readings
Stan,
You may be experiencing some component 'aging', but there is no known
problem here. I have had my K2 SN 00020 set up for at least 2 years now
with no apparent change of S-meter response.
I guess it is possible that your trimmer for the AGC Threshold voltage
adjustment may have been bumped
Sounds like a bad 20 meter crystal to me.

A very strange way to solve my problem was to «hard reset» the K2. And
setting up from scratch with all needed values.
This is the second time that I solved a problem with a «hard reset». The
first time, a friend of mine brought me his K2 because he had TX problem
in CW. His problem was like

pulses from the I/O-controller. But: how does the controller know the

I did the same test for oscillation from each crystal some time back

Actually, it's not that difficult. We reset all the relays when a
tune session begins, then adjust them as the magic algorithm
proceeds. When the desired tune level is achieved, we save the relay
state information in non-volatile memory for later use (next time we
OK Thanks Don and Tom,
QRP below 5w is rarely used
here on the K2. I pull the K1 out for those events.
Anyway, I will get a bundle of 1N5711's off Elecraft next time I put an

I just finished building my electaft and I agree with you about the LCD

My group usually puts up a V antenna for 80 and 40 on field day and

When I operate my K2 between 7180 and 7190 Khz the VCO seems to worble or

I contacted the fellow from Kodiak who said replacing the 22MHz xtal

of them failed in K1s.

I found a problem on a new K1 board with the silk screen markings.
Apparently the new ROHS compatible boards have solder pads that the
silkscreening ink does not stick to, so some of the parts orientation that
used to be present is now gone - and I do not believe the folks at Aptos are
aware
Dave,
This is the old WAOF (wierd at one frequency) situation. If you have it, it
will be found near 7167 kHz. It is most noticible on receive but it affects
the transmitted signal too.
Reduce the lead length of everything that you can find in the general area
of the VCO and PLL - even flush
