After about 2 weeks, 40-50 hours and some troubleshooting, K2 number 5037 is
alive and beaconing on 20 meters at 30 watts.
This one has the KPA100, KSB, K2IO, noise filter, audio filter and 160
adapter. Pretty much the full boat.
Observations. The KPA 100 is almost as much work as building the RF board.
Lots and lots of parts. I am still missing a couple of minor caps, but
substituted them in from the junk drawer. This is the first KPA100 that I
have built, and it is one first class, semi-complex piece of gear. Very
nice. Also makes the rig very heavy!
I still need to re-align the filters. The 1.5 and .700 CW filters are ok,
but the .400 and .200 read about 2KC lower when the tone is centered in the
filter. Also still need to calibrate the VCO and SSB filters.
I have also made several contacts on PSK with the QRP version, so I am
assuming that the sideband operation will be ok. I don't have a mike with an
8 pin plug, so I have not been able to try it on voice.
This one is not staying here. I sold my other K2 #272 about 2 years ago, so
this is the first time that I have had one in the shack for a while. First
class rig, but I knew that. This one will be going to a good friend who is a
DX hound/CW nut so I am sure that he will appreciate the rig.
Kudos to Wayne and company. I have not seen the newer rigs with the changes
that have been made, and it is impressive to say the least. I don't think
that I will be going near a soldering iron for a little while now. Thanks to
Scott, Elecraft and the list for the help that I got when needed. Most if
not all of the problems that I had were build created. Just need to stop
building when I get tired.
