Re: [Elecraft] LED bulbs
Please forgive a really stupid question, but woulda High Hat fixture (like the ones that were justinstalled in the ceiling of our recently renovatedkitchen) be considered an enclosed luminary in this context? My XYL and I considered putting in LED lamps/bulbsat that time, but when I went shopping at our localhome improvement stores, I became very apprehensive... Luckily, the shack (which is in the garage) is rightoff of the kitchen, so any RFI will be resolved easily :-) Thanks, Brandy, N1HO GRANT YOUNGMAN n...@tx.rr.com said: The one downside I’ve found so far is that virtually all of them specify “not for use in enclosed luminaries”. __ 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
Re: [Elecraft] Anyone using a DESpole?
I can’t tell whether it is a coupled-resonator dipole or a fan dipole. I’m betting on the latter. I don’t think you could cover that much bandwidth with a coupled-resonator design. The drooping ends are a reasonable choice for a limited space dipole. wunder K6WRU CM87wj http://observer.wunderwood.org/ (my blog) On May 12, 2015, at 10:18 AM, Wes (N7WS) w...@triconet.org wrote: There was a non-technical review of it in the March 2014 QST (p.54) I'm put off by the hype: /*Breakthrough electromagnetic and mechanical engineering powers high-performance dipole arrays covering multiple bands with full-size efficiency. */This appears to be nothing more than what Gary Breed calls a coupled-resonator dipole in, /The ARRL Antenna Compendium, Vol 5./ and republished in the /ARRL Antenna Book.///(Chapter 10.5) in the latest edition.//Hardly a breakthrough./ /I'm looking at building one, without the bent elements, for the WARC bands.

Re: [Elecraft] MFJ's new Internal K3 Tuner, anyone tried one yet?

Nothing dicey about it ... MFJ doesn't even need to know anything about the tuning algorithms or controls. The K3 CPU controls both the tuner L/C values and the antenna selection via a serial bus and series of serial to parallel shift registers/latches. The only engineering MFJ needed to do was copy Elecraft's KAT3 schematic. The only value engineering is to do what Elecraft does at lower production costs and perhaps loser cost parts. The real question is the ethics (and legality) of copying Elecraft's schematic. The only way the MFJ tuner works properly is if it copies the L/C values and controls exactly. 73, ...

[Elecraft] powermeter
This is probably a very naive question, but where should a powermeter that measures Forward and reflected power be positioned? Should it be between the Amplifier and the Tuner, which could safeguard the amplifier if there was a high SWR, or after the tuner, (ie, between the tuner and the antenna)?

Re: [Elecraft] Introduction
Ken - I agree that you'll most likely relegate the Eagle to second status. If you hook the K3 up to the Centurion, be sure to follow the instructions for the K3. It's different. Fred Cady's (KE7X) book on the K3 is well worth having also. I bought it on CD so I can search it, and I took the CD to Office Depot and had it printed. I like to nap with it in the recliner.. 73, Mike NF4L On May 12, 2015, at 9:18 AM, Ken Bandy, KJ9B k...@arrl.net wrote: Hello, all. I recently signed up for this list, as I am thinking of adding a K3 to my shack. I have downloaded the manual for the K3, and plan to study it as I can. I currently have a TenTec Eagle transceiver and TenTec Centurion Amplifier. I am thinking of adding the K3 to have redundancy and keep the shack (at least the HF part) all American. Any thoughts from users that have compared the K3 to the Eagle? I have been very impressed with the receiver on the Eagle! Another use for the K3 would be as a portable rig for occasional trips using a Buddipole. I plan on visiting the Electraft booth at Dayton this weekend to take a closer look at the rig. So, perhaps I will meet some folks there!
