That's what the Chinese do Start taking parts out of the certified design until it quits working, and then put the last one back. Clay E.

Re: [Elecraft] K3S-KPA3 100 Watt Amplifier not working
Hi Dick, By 'not working' I presume you mean that advancing the TX Power control above 12 watts does not yield increasing TX power output? Does advancing the TX Power control above 12 watts produce any increased TX output power or none at all? Here I presume you have an external wattmeter with which to measure TX output power. The K3s uses the KPA3A power amplifier, which is a RF MOSFET-based amplifier. The 100 watt amplifier is either bypassed or inserted inline after the KLPA3A low power amplifier using PIN diode switches and depending on the setting of the TX Power control. That you're still able to measure 12 watts TX output from the KLP3A suggests the 'bypass' path through the PIN diode switches is operating correctly. Keith, WE6R, the Elecraft tech guru, had posted some common failures on the KPA3A board - you can search them on this forum or the K3 groups.io forum. He may chime in here before I can locate his very helpful posts. 73, Mike, K8CN __ 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] New Bands
The K3, being a superhet that involves mixers, uses very narrow-band transmit band-pass filtering that doesn't allow operation midway between 10 and 6 meters. So it is excluded in firmware. That said, the K3 provides very versatile support for external transverters. 73, Wayne N6KR > On Jan 25, 2023, at 11:22 AM, Christopher Hoover wrote: > > What about the K3 for RX on 8m?

[Elecraft] K3- part fell out
Yaw! I have been working with SMD -components. Marking; 3k3 is A 3300 ohm (3.3 kOhm) resistor 3.3.ohm resistor is marked 3R3. As I have been working as A radio- TV mechanics I sometimes was targeted with A joke. "Put an extra component loose somewhwere in an equipment and cause a nerval breakdown". Maybe not in this case. -- 73 & CU Penna, OH2G, OH2CG __ 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
