Re: [Elecraft] K6XX CW Indicator SMD Button LED Key installation

Doug, I have built several of the LED IN A KEYCAP for both the K1 and K2. Unfortunately, I was never successful in soldering wires to the SMD LED that Ron (SK) supplied toward the end of his last run of the CW Tuning Indicator. The 3.3k SMD resistors may have been his solution after I told him

Re: [Elecraft] xv tansverters

Joe, Errata that was issued after the ship date of your units is not applicable to your unit. This particular errata applies only to the XV144 and it was necessary because the crystal manufacturer supplied a crystal that was slightly off frequency from the prior one. L19 compensated for that

Re: [Elecraft] Best Audio Interfaces 2020?

You do not need an exotic soundcard for digital modes, most any will do. The big thing to pay attention to is the noise level, which may or may not be specified. The soundcards reviewed at www.telepostinc.com is a good resource, but those listed are for panadapter purposes, and need a wide

Re: [Elecraft] White noise on K3transmit

Mike, Start your investigation simply: Look at the deflection on the ALC meter. If you do not have 5 to 7 bars flashing on voice peaks, you are not driving the audio enough. 73, Don W3FPR On 6/14/2020 10:58 AM, Mike Furrey wrote: I just set up to operate in the 6 meter contest and after no

Re: [Elecraft] Firmware

Joe, I cannot recall any instance where the firmware upgrade broke the K3 - same for the KX3/KX2. There have been a few who suspected a problem with a firmware upgrade, but it turned out to be some other problem. I would recommend that you simply upgrade to the latest and be done with it.

Re: [Elecraft] K-3 Pwr/Cmp/Mon button problem

Kim, That sounds like a bad encoder. Replacement is the only real fix. It is tough to desolder the tabs, but otherwise not too hard. 73, Don W3FPR On 6/13/2020 11:35 AM, Michael K Bottles via Elecraft wrote: I have a older Factory built K-3 (s/n 3530) The Power/Compressor/Monitor control is

Re: [Elecraft] KX3 volume control inop

Jerry, Can you change the monitor/sidetone level? How about the RF Gain? If not, check the ribbon cable inside - unplug and reseat. If still no solution, it is possible you have a bad encoder. 73, Don W3FPR On 6/13/2020 11:14 AM, Jerry Ford wrote: Good morning all: I'm having a rough day

Re: [Elecraft] stripping insulation

Thank you Kent for that thoughtful caution. I have a holder for mine. When I use it for wire stripping, I lay it on its side on a heat resistant surface on the workbench. No need to touch anything other than the handle and the trigger to start the suction. 73, Don W3FPR On 6/12/2020 3:48

Re: [Elecraft] stripping insulation

For those who own a desoldering iron like the Hakko 808, stripping the enamel from heat strippable wire is quick and easy - just like a solder pot. Melt a bit of solder on the tip and push the wire into the tip center. Wait a bit for 'smoke' to appear and then pull the trigger. Presto,

Re: [Elecraft] stripping insulation from enamel wires

Yes, that always works, BUT if you nick the wire, it will break, especially on smaller gauge wire. For #20 and larger it is likely OK. 73, Don W3FPR On 6/12/2020 12:24 PM, qr...@roadrunner.com wrote: The old tried and true method is to use an X-acto knife to scrape the insulation off with.

Re: [Elecraft] stripping insulation from enamel wires

Robert, Those instructions are for heat-strippable wire. If you have enamel or formvar covered wire, that must be mechanically stripped. 73, Don W3FPR On 6/12/2020 10:02 AM, Robert G Strickland via Elecraft wrote: Here's an old problem that I've never solved: how to strip the enamel

Re: [Elecraft] Spurs on 6 meters on FT8

Barney, I assume you are talking about a K3/K3S or KX3. For those you need to increase the audio drive so you have 4 bars solid showing on the ALC meter with the 5th flashing. That is the NO ALC point on those radios. It is required for proper power control. See the article on my website

Re: [Elecraft] K3 on motorboat.

Barry, Sometimes we have to put on the Scientists hat, but when the rubber meets the road and we have to come up with a product, we have to put on the design engineers hat and say that how much compromise is required to meet 1) customer demands, 2) budget constraints, 3) speed to first

Re: [Elecraft] K3 on motorboat.

Barry, Well, when I was with IBM, my title was Engineer/Scientist, so I got credit for both. Engineers have the education and training to do research as well as making those judgements during design that sometimes result in compromises. 73, Don W3FPR On 6/10/2020 1:15 PM, Barry wrote: I
