[Elecraft] Subject: KPA1500 Power Level
I looked at the link given in part of this discussion regarding efficiency and dissipated power data at various output levels. Very revealing. During a recent virtual hamfest I spoke to the Elecraft designer of the KPA1500 and he confirmed that the heat dissipated remains nearly unchanged whether you are running 500 out or 1500 Watts out. If owners of the KPA1500 reduce power output to "go easy" on their amp by reducing power, they are not. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 Display Won't Shut Off
I've had the same effect by setting the K3's Alarm to ON then turning off the p/s. When the p/s is turned on again (and maybe the K3 Power button pressed; I forget the exact sequence now) the LCD backlight comes on. So, you might want to check the Alarm setting. 73, Drew AF2Z On 09/16/21 18:30, Jim McCook wrote: When I plug the ACC connector cable for the KPA1500 into my newly acquired spare K3, the POWER button doesn't shut off the backlight in the display or the P3 that's connected to it. As soon as I remove that connector or shut off the PS, it powers down normally. This doesn't happen with the other K3 using the same cable. All is normal. Looking in the archives I saw something about a D10 removal, but couldn't find the specific info as to where it is and what the access is. It was described as an early mod, but this K3 is a later version #6695. Any specific ideas where the problem is and how to fix it? 73, Jim W6YA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to pu...@af2z.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K2/100 RS232 trouble
The problem of using a standard cable with the serial port is not that it might fail to operate as a serial port, but rather than it might permanently destroy the (non-RS232) internal signalling within the transceiver. ... In fact there seem to be two pins that are used for signals that cannot tolerate RS232 voltages. The K2 "A to B mod" has some modifications that at least seem to reduce some of the damage. I don't remember it being announced as such, but reviewing the mod status of my K2 after some time found some snippets I had not seen before. Things still would not work and I am not sure the K2 is fully protected but some protection is added and the damage should be less. If you still did make the boo-boo, this link from LA3ZA may be useful: http://folk.uio.no/sverre/LA3ZA/blog/K2/N0SS/k2_wrong_ser_cbl_damage.pdf Geert Jan __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
