[Elecraft] KX1/KX3 Accessory Cable Source (for external key)

Who can point me to a source for a right-angle 3.5mm stereo plug to bare wire cable for the KX3? I wish to make up some cables for outboard straight keys and bugs. I would solder either a 3.5mm mono or 1/4" mono in-line jack to accommodate the external key. TNX fer any help es 72 Howard

Re: [Elecraft] kx1 and earchi

I've done a lot of backpacking, and used a fair amount of RG-174. 12 or 13 feet of that weighs very little - about 13 grams or 1/2 oz., and would add to flexibility of antenna placement too. Thats my experience anyway. 73 Chip AE5KA On Sun, Feb 12, 2017 at 11:26 AM, Don Wilhelm

Re: [Elecraft] kx1 and earchi

Chip, A length of wire is much lighter than any coax, including RG-174. Important for those backpacking. 73, Don W3FPR On 2/12/2017 8:52 AM, Chip Stratton wrote: Try about 12 feet of RG-174 between your rig and your earchi transformer. That will make your .05 wl counterpoise for 80m without

Re: [Elecraft] kx1 and earchi

Try about 12 feet of RG-174 between your rig and your earchi transformer. That will make your .05 wl counterpoise for 80m without much weight and without much loss on the higher frequency bands. Chip AE5KA On Sun, Feb 12, 2017 at 6:42 AM, kg8jk wrote: > Just picked up a couple

[Elecraft] kx1 and earchi

Just picked up a couple of toroids at a swap and want to make an earchi antenna for the kx1. As I want to take this backpacking the plan is to connect directly to the radio and use a counterpoise instead of using coax in order to save weight. Has anybody found the secret length for the antenna to

Re: [Elecraft] (KX1) A Story for a Winter Day in NY

Let me answer for myself. I want a schematic for both fixing it and learning how it works. I don't really think I will learn much about how it works from the schematic because most of how it works is in the firmware and not the hardware. As for fixing things, I have made repairs to both my K3

Re: [Elecraft] (KX1) A Story for a Winter Day in NY

Mike, I find this a very curious belief. Do you want a schematic to know how the thing works, or how to repair it. If you only want to know how the radio works, would a block diagram and a fairly detailed explanation from Wayne be enough (given they want to protect their design as much as

[Elecraft] KX1 discontinued

It is indeed a sad but inevitable occurrence, time and technology move forward ! The KX1 was my first venture into the world of Elecraft, I bought mine in 2010 and still use it, it has gone everywhere with me in my travels, from mountain tops to kayak camping in the Everglades. I've owned the

Re: [Elecraft] (KX1) A Story for a Winter Day in NY

It's understandable, though: At least two radios I know of are clearly copies of the KX1. 73, Scott K9MA On 2/9/2017 20:20, Mike Morrow wrote: Wayne wrote: ...the KX2 is about the same size and has so much more capability. BUT...unlike the KX1, the KX2 has no schematics available to

One of my fondest KX1 operating memories was working F5VHY on 20m CW while operating pedestrian mobile with my KX1. I was using a 4 foot loaded telescopic whip and a 13 foot drag wire and standing out in the middle of a field at Lobstercon. Cheers Michael VE3WMB
