Re: [Elecraft] In Line Power Pole Fuses

25 amp fusing isn’t a lot over overhead for a K3 with KRX3, KIO3a, P3 with the SVGA board and the PR6-10 preamp in play. It all adds up. Use what is appropriate for your rig combination. 73, Rick NK7I Email spiel Czech corruptions happen > On Jul 21, 2021, at 10:33 PM, Ray wrote: > >

Re: [Elecraft] In Line Power Pole Fuses

Dave and all, Placing the fuse near the power supply end is the way to do it. In the event of a short, the power wire can spew metal and start a fire. Always fuse near the power supply.  A fuse at the equipment end will only protect the equipment, but will expose the wire from the power supply

Re: [Elecraft] In Line Power Pole Fuses

Hi, I am unsure what you are asking... If you are asking about fuse values, I select values a bit above the max peak current I expect. For my K3 I use a 30 amp fuse. If you are asking about voltage drop, and want to know what the K3 sees, there is a built in volt meter in the K3, (see the

LiFePO4 has several other advantages, besides not swelling during charge. (Swelling is what caused fires in early devices in places like airplanes. They contained the battery with no room for expansion resulting in burst cases and exposed lithium.) The other ones that come to my mind are:

I've been using a CMOS4 with V0 emulation across all my rigs (when in the shack) for 20 years now.  I've always liked it and send better with it than most other keyers or rig's keyers, though lately some rig's keyers seem very similar.  Does anybody happen to know where I might find details of

I also prefer the K-5 to the Winkeyer, and I use the V0 timing too. The K-5 is no longer available but the CMOS 4 keyer has the same features except it has only four memories instead of six and is smaller. I have both. https://www.hamsupply.com/cmos-4-keyer/ 73, Jim N7US -Original

It's a version of mode b with slightly different timing. It is easier to send with fewer mistakes than the usual mode b. I got addicted to it and had a hard time when I changed to the mode b in the WinKey. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

The Logikey keyer by Idiom Press lists no less than ten "emulation options", or keyer timing modes. They are numbered "V0" through "V9", including three different Curtis A modes, three Accukeyer modes, and others. "V0" is the best timing I've ever used on a keyer. I don't know whether it's A,
