Re: AX1
WRC makes decent whips too - though I don¡¯t have a Chameleon to do a direct comparison,. https://www.wolfrivercoils.com/order.html 73 -- Matt N3AR

Re: AX1
Those are the same that MFJ used to sell before they went closed their doors. I use one for several HB antennas and it works very well alone. You can even base load one easily. 73, Mike n6zw

Re: AX1
Except that the AX1 isn't enough of a vertical to actually act like a short vertical.? If you model an AX1 and look at the current distribution you will see that most of it is in the counterpoise

Re: AX1
I¡¯ve used this strategy on bare summits above 3-4000 feet with some success. Unfortunately at sea level or low elevation you¡¯re just warming the earthworms. Any type of short vertical with an

Re: AX1
You should try the EFRW sometime just laying on the ground, or maybe laying across a rock.? I'll say again ... most of the radiating from an AX1 comes from either the counterpoise or the shield of

Re: AX1
I forgot to mention that I also carry a EFRW in my little bag,that of course is more efficient than almost short loaded vertical. Mine is Adam¡¯s K6ARK clever design that incorporates a 9:1 balun

Re: AX1
It¡¯s a matter of trade offs that each operator is willing to make. No doubt that other larger antennas can be more efficient,but how much are you willing to pack around? Last summer I made a trip to

Re: Help Identify Kit
WOW! Bingo, the treasured missing piece of information. I had all but given up but now having a fighting chance to bring this thing to life. THANK YOU! Other things on the bench for now but when I get

Re: AX1
I don't think anyone can deny that an AX1 is a very convenient antenna, but isn't the elephant in the room still efficiency? Looking at Doug's antenna, judging from the whip size, I'd guess it's

Re: Help Identify Kit
Actually I did build one before I had a license for someone.? Didn't retain the manual as it was his.? He is now SK by over a decade. And it seems someone found that missing peice, the arts

Re: AX1
Hi Dan What you say about your backpack is true. I¡¯m a hiker and portable operator so keeping size and weight down is essential . The more bits you carry the longer it takes to put together and take

Re: Help Identify Kit
This is the closest I have come, as this is the same board I have. Problem is, while many components are pretty obvious, what are the values of the 21 resistors and numerous capacitors shown in their

Re: Help Identify Kit
I¡¯m not intending to be obnoxious or anything, but isn¡¯t there anyone on the list who actually built one of these kits back in the day and can just take a picture of the assembled board? Brian

Re: Help Identify Kit
With the schematic (in the QST article) and the actual board in hand I think you should be able to reverse your way into a parts placement diagram. Especially if you go stage-by-stage, using

Reply from Dave Benson, dead in the water unless someone actually still has those parts placement drawings. Hi Richard- Unfortunately, what you have there is a drink coaster. My documents were created
