I just added some pictures of the kxb-3080 installation, to my web
page, if anyone is interested in having a look at them. http://www3.ns.sympatico.ca/ppike/kxb3080.html Please note, in the first picture, L1 and L2 are supposed to look the same. I didn't notice this until I looked at the picture! The rest of my kx1 can be seen here: http://www3.ns.sympatico.ca/ppike/kx1.html 72, 73, Paul - ve1dy -- QRP-L #2507, SKCC #91 www3.ns.sympatico.ca/ppike _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Don't be in a hurry to adjust those turns! They only look the same when you first wind the toroids. If you adjusted the turns as described in the next-to-last step on page 17 of the manual, they may well need to look like that. That step advises you to adjust the green turns on those toroids as needed to get the best results on 40 and 20. Remember that 20 should be 1/4 to maybe 1/2 watt below 40 meters. If it's more than that, you adjust the green turns to bring 20 up. What you ended up with isn't uncommon at all. Yes, it's possible to balance the power on 40 and 20, but for proper harmonic rejection the 20 meter band should be on the edge of the bandpass characteristic. That's why 20 should be a little below 40. Many KX1s with the KXB30 or KXB8030 show a decided peak in output at 30 meters that is above either 40 or 20. Nice looking installation there in a very nicely-built KX1!! Isn't that white Kynar hookup wire neat stuff to use in small spaces like that?

Elecraft could have stopped to design a whole new pc-board for the KX1 to come up with a 4-band unit, then sold a new kit that those wanting to add 30 or 80 meters would have to buy and build. The same was true of many mods to the K2 over the years that have kept the oldest K2s working like the latest units built by the addition of a few wires, jumpers and "daughter boards". In either case the owner wanting to get the latest features would have had to buy a whole new rig or, at the very least, done a very expensive upgrade that would have scrapped much of the old rig. Adding a few wires led to a much quicker, lower cost and still very clean design. As the wise Sage observed, "...all things in moderation..." to which the Ham adds, "...even wires."

While making some baseline measurements on my KX1 in preparation for the install of the KXB-3080, I discovered a mysterious 5 ma draw with the rig turned off but connected to an external 12v battery pack.
It turns out that the K6XX visible tuning indicator I have installed draws 5 ma continually regardless of the position of the power switch. I did the installation according to the instructions from Tom N0SS's website. The indicator works great, and is a wonderful addition to the KX1, since you cannot easily zero beat the a received signal (the sidetone menu setting mutes the received audio, you need to have a good "audio" memory). I just wonder if this constant 5 ma draw might pose a problem if you leave batteries in the internal battery holder unused for a long period of time -- potential leakage perhaps. It's not likely to be an issue one just installs batteries for a weekend's use, then takes them out. But before I had the tuning indicator, I left my first set of lithium AAs in for about 6 months. After I'm done with the KXB-3080, I may look around for another point to pick up V+ that is switched by the power switch. 73, Mike N2HTT _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Re: KX1 drawing 5 ma turned off!

I lost a set of lithium batteries too. Go to N0SS's web site,
http://www.n0ss.net/k6xx_cw_tun_ind_smd_v2_assy-align_kx1_ver.pdf and read the documentation for the KX1 version. Down near the end, there is a note on the page that shows a pictures of the wires and where they connect on the KX1's board. It mentions that the earlier version of the documentation had you connect the Tuning Indicator's power lead to the wrong side of the KX-1's on/off switch.
