Re: [Elecraft] Firmware development

Hi Tim, Like any product development company, we have to strike a balance between creating new products and enhancing old ones. That said, we've provided literally hundreds of new K3/K3S/P3/KX2/KX3/PX3/KPA500/KPA1500 firmware revisions over the past 10 years, for both MCU and DSP code. Many of

Re: [Elecraft] KX3 keyline questions

Steve, Are you sure you're looking at the ACC2 ring contact? Ring is KEY OUT; tip is GPIO, a logic signal configurable in the ACC2 IO Menu entry. Wayne N6KR > On Nov 21, 2020, at 1:12 PM, Steve Zabarnick wrote: > > I'm exploring using my KX3 with the QRP-Labs 50W Amplifier. In measuring >

[Elecraft] Seeking reviewers for the updated K4 Programmer's Reference

The K4 Programmer's Reference is now at a point where we'd like to get additional input. This document is intended for application developers, as well as for K4 users who wish to create their own macros (strings of commands) for assignment to switches on the radio itself or on a K-Pod. We'll

Re: [Elecraft] KX2 External battery question

I would definitely *not* use the KXBC2 charger with anything but a KXBT2, or an exact equivalent pack, for safety reasons. The voltages and currents are targeted specifically at 3 Li-Ion cells (11 V). Just to give you another [probably biased, beware] opinion on the KXBT2, though: The internal

Re: [Elecraft] K4 RX overload protection

Hi Ed, Each of the K4's receivers has a fast-acting Carrier Operated Relay (COR) that activates between +20 and +25 dBm. When the COR triggers, it disconnects all active circuitry of the associated receiver from the antenna. COR hold time is programmable. For signals that are below COR level

Re: [Elecraft] sensitvity k4

Hi Richard, All K4 models utilize the same front-end circuitry (preamps, filters, etc.), so all will have virtually identical sensitivity for a given gain setting. These in turn will be similar to the K3/K3S. 73, Wayne N6KR > On Oct 12, 2020, at 4:52 PM, Richard Donner wrote: > > Anyone
