[Elecraft] Elecraft CW Net Announcement

Good Evening,    I started the Elecraft CW net on June 6th, 2002 to commemorate my uncle's action on that date in 1944.  He started early, loading into a plane for a short flight across the Channel.  Then jump out of a perfectly good aircraft, in the dark, while getting shot at. They were tol

At high power the KPA1500 is the most efficient. At lower power it will generate the same internal heat or more. John KK9A Kevin Robertson KD2WCY FT8 is a weak signal mode, designed for low power. Given its high duty cycle, you are asking for trouble if you operate your power amplifier in FT8

[Elecraft] K3/0 AF gain control across a RemoteHams link

2022-06-04 Thread Bill Weaver
A buddy and I are working on setting up his k3/0 -> my K4 remote link using Remotehams. When he adjusts the AF gain on his K3/0 there is no change in the audio level at his end (the audio level varies here on the K4). The AF gain works fine when adjusted on the RcForb Remotehams client at his en

Hi Kevin, The K2 is only rated 100% duty cycle at 5 Watts and 50% duty cycle at 10 Watts. Even though it will put out 15 Watts it should only be run there on SSB and CW and then sparingly. It should not be run on digital modes above 10 Watts and really should not be run at more than 5 Watts on d

It isn't "designed for low power."  I don't, nor will I have, a KPA1500, but I run my KAT500 at 400-500 W on FT8 without incident. Wes  N7WS On 6/4/2022 6:52 AM, Kevin Robertson via Elecraft wrote: FT8 is a weak signal mode, designed for low power. Given its high duty cycle, you are asking f

It is a weak signal mode, not necessarily a low power mode. If a station you need for new country is -24 and is running 1500 watts then most likely he will not hear you at low power. You will need to run QRO. Use the power needed to make the contact. Dave wo2x Sent from my waxed string and

Tim mentioned “A local here has a loaded K2/100 that he's been trying to sell for a while but has only received what he perceives as low offers” Bear in mind the K2 has been around for over 20 years, and was built from a kit by hams with variable degrees of soldering skills and had quite a few m
