Re: [Elecraft] denatured alcohol vs. Everclear
We used Vodka for cleaning VHF and UHF broadcast transmitters. Told by RCA engineers that that is what was in their expensive bottles sold to radio stations. Other alcohol agents left a residue that would eventually arc over.

[Elecraft] lightning protection
In addition to everything else suggested, I disconnect all coax cables outside my home and let them lay on the ground. I use a trailer type connector to unplug my antenna rotator. I further use a heavy duty DPDT switch for my full wave 80 meter loop, not to ground but to open. (lightning doesn't see my antennas any more than the coffee cup in my hand) Keep in mind that I live on the ridge in south central Florida running down the center of the state from Lake Wales to the north and sloping to the south into the Everglades. (From Tampa to here is the lightning capital of the western hemisphere) We are second in the world to a location in south eastern Africa for lightning strikes. In the 25 years I have lived here we have had several hams get hit by lightning that followed code to a "T" including a perimeter wire completely surrounding their home and tied to the main electrical ground, towers, polyphasers and or lightning arrestors bounded to at least 10 foot rods going into our sandy soil. In the most recent hit, a good friend and local ham in Lake Placid had his home burn completely to the ground, with his wife just narrowly escaping the inferno. He had everything grounded correctly including a 4 gauge perimeter wire completely surrounding his home. John's 120 foot tower was not hit and his coax cables and pl259/s were not scorched. In his case the lightning hit the Duke power company line coming into his home and exploded into his house with a massive hole, and according to the state inspector it was textbook 101, blowing through all electrical outlets in his home at the same time. His wife had less then 30 seconds to get out. By the way, John KK4LI, installs towers, and antennas for a living. He also conducts classes on lightning protection at the Tampa hamfest. Of further interest, our number one item for getting hit in our area seems to be Dish and Direct satellite dishes.

[Elecraft] KPA500 failure
While getting ready for the Elecraft net today my KPA500 would not transmit. In bypass mode swr is 1:1. When placing in operate mode I get no output with my K3 showing high swr. Tried my loop, vertical, and Hex beam. All show low swr on the K3, KAT500 and the KPA500 in bypass. I took the KAT out of circuit and no change. Unhooked all antennas and then reattached one at a time, no joy. Ran a new coax between K3, KPA500, and then just between the K3 and KPA500 and got the same thing. Can run 100 watts out with K3 with low swr on all my hf antennas as long as KPA500 is bypassed. When I put it in operate I get no output and K3 shows high swr. It has been working flawless on all bands and modes. Usually run 28 to 32 watts input for around 500 out. Anyone have any ideas on what might have happened. Thanks for any thoughts.. 73, Don, W4CBS Sent from Yahoo Mail on Android __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] Re K4
Watch Eric for hints. Couple years back at Hamcation in Orlando I asked Eric if there was any possibility of a KPA1000 to which came the grin then he replied "why only 1000?" There's your sign.

[Elecraft] Flumoxed
Lee, it looks like your inverted L wire has stretched. Check with an antenna analyzer and you will probably see your resonate frequency is lower than 1.8 Mhz. Perhaps time to do some triming.

[Elecraft] ARRL book on receiving antennas
Having been a ham since 1956, I also agree from my experience, that I along with every ham I knew, used the same antenna to receive and transmit. From my first home brew one tube, through my first Globe Chief kit, through Globe Scout, NCX3, and Globe GTX 550, all in the 50/s and into the 60/s, and all had the same antenna for receive and transmit. I too, went from the dpdt knife switch, to the Dow Key relay. My QSL collection confirms this for the stations worked during that period. 73, Don W4CBS Sent from Yahoo Mail on Android __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] K3 No power out
Yes I can set it at 35 watts which is what I usually use to drive the KPA 500, and speak in the mic for ssb and get no power out. In cw at the same 35 watts, when I send code either straight key or padfle. 0 watts out. Same results if I attempt to run bearfoot at 100 watts or 5 watts, I get no power out. Receive is working fine, the P3 is working normal, and the KPA 500 and KAT 500 track bands as I change them. I will try again tomorrow after a night of sleep.

[Elecraft] K3 No power out
I have enjoyed the wisdom of this group and have learned so much but now it is my time to ask for help. My K3 is showing no power out. I have the K line. The relay clicks when going from 11 to 12 watts. I can set the power up to 110, but when I hit tune I get zere watts shown and verified by my watt meters. Makes no difference of mode, band, dummy load, resonant ant, or multiband hex beam, 80 meter horizontal loop, or 40 meter vertical. There is no output to tune anything. My last contacts showed no problems. Worked 10 meter cw, 20 and 6 meter ssb ok just two days ago. It seems to be receiving fine. The P3 display is normal, the KAT 500 and KPA 500 change bands with the K3 as they normally do. I have rebooted the K3 several times and have killed the master AC power to everything only to bring it up to the same thing. The ALC, compression, mic gain all register correct, where I always run them. I have checked to make sure the Test button has not been ingaged. Press XMIT and all I get is 0 W. I am sure I have forgotten something simple. Would appreciate any help.

[Elecraft] Massive opening on 10 and 6
Wayne, thank you for the reminder about adding memories on 6 meters. After reading your note I added 50.130, 50.135, 50.140 and 50.145 per your suggestion. This morning, after a sked on 20 I checked the calling freq on 6 and heard nothing. Then I hit scan and to my surprise there were QSOs on 3 of the 4. Soon I had new grid squares from PA, VT, and Ontario from my EL97 here in south central Florida.

[Elecraft] Back up power
Living in Sebring Florida and having survived ground zero for three cat 2 to 3 hurricanes in 13 years including Irma, I have had good results running a back up generator shared with my next door neighbor. I have switched from whole house AC to mini splits. My Florida room has a 110v minisplit by Desuki that I was able to use to keep the room at 72 degrees during a 10 day power outage. On the same line I ran plugin lights in the room, tv system, line to main house refrigerator, and into my shack to run my K-line barefoot, where I relayed weather info between county EOC and National Weather Center, as well as traffic into and out of National Hurricane Center. My wife and I enjoyed our two recliners in comfortable conditions until the power was restored. The AC mini splits have now replaced my central AC in the whole house and my utility bill has dropped by one third. 73, DonW4CBS Sent from Yahoo Mail on Android __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
