Re: Travel to Europe with KX3 questions

I flew cross country with a person that used an electric wheelchair. There were a number of questions and requirements she needed to negotiate before they would allow her batteries on board. Check with your carrier before just showing up at the boarding gate with your battery. May save some grief! H...

Re: Trapping the EFHW?

So you did lose the resonance on 15 and 10 meters.
Thanks for going thru all the work to find this out, Mike. Your efforts are appreciated and I learned something!

Re: JNC cs-818 tuner

Hi I've been away for a while, so I missed the last part of this conversation. I had the same idea, only using a switched l-match type tuner to place the capacitor eitther in series or shunt to match high or low impedances. And I was gonna wind the antenna in to I think 57' for the random wire lengt...

Re: Trapping the EFHW?

Hi Mike I went thru a ton of stuff online and in my stash of info here, and I can't find anything about using a trap and still having the multiple-halfwave advantage of basic EFHW. Even for a basic 40-30-20m using a trap for 30 meters also had a trap for 20m. I'm not saying it's impossible, but if i...

Re: JNC cs-818 tuner

Hi Mark- A lot of auto tuners, and internal tuners in modern radios are not able to tune much more than a 3:1 SWR. Maybe try a 9:1 transformer between the antenna and tuner: http://www.earchi.org/proj_homebrew.html This is not the same as a 49:1 transformer for end fed half wave antennas. Dont get t...

Re: what is "rock bound" or "rock lock"?

Ah the memories! I made a crystal holder for my dad back in 4th grade. Just an 8" 1x2 with his call woodburned on the front and holes drilled in the top to plug your crystals in. Novice class operators were required to use crystals back in the bad old days. My Heathkit HW-7 has a socket right o...

Re: New ham interested in CW

I thought about getting an ft818 with one of the pandemic checks they sent out. After researching the VHF/UHF CW activity in my area, I got a new bicycle instead. It just didn't seem worth the investment or effort.

Re: New QRP Labs Radio - QMX

I saw this at Hamvention today. You could get the kit and the case for around $120. I have too many 80-20 meter rigs. All these new radios seem to be capable of working on all the HF bands, but the low pass filters seem to be hard to supply. I dont know why. If you can come up with auto antenna tune...

Re: Why does QRPGuys EFHW use less than a half wave?

Did you get your kit directly from QRPGuys? If not, its a cheap Chinese ripoff. Toroid could be anything.

Double-check your windings count. Its easy to be off, especially if its your first time winding one.

What are you using to measure SWR? Did you cut your wire for 20m?

Re: New rig for the summer!

I really wanted the whole rig; radio, power and antenna to fit in this case I found. That's the reason for the homemade key and wire winders. A case for the radio would just be too large. Im sure I'll get bored with it and switch it to something else eventually. Maybe then I'll even use the file Kev...
