this video LIVE demo is using a Raspberry PI 2b and FLdigi together as a CW KEYER, remote rig control AND a logging book...
- FLdigi does it ALL !
- A BIG THANK YOU TO W1HKJ !!
- this setup does not tax the pi's cpu and runs perfectly
the first part of the video demo's receiving a station on 40 meters and changing some of…Continue

Using an audio derived cw keying circuit to key CW on the K3S : http://qrqcwnet.ning.com/forum/topics/what-circuit-for-computer
- with the circuit attached to the K3S cw keying jack...and being key'ed remotely via a voice chat program called MUMBLE:…
using MUMBLE and MORSE CODE audio tones, and varying the Mumble output volume from 15 percent to 200 percent, this video demo's VLevel keeping the volume output of Mumble to be extremely stable at a near zero DB final audio output to the sound card, no matter the level of volume at VLeveL's input...VLevel is acting as an AUTOMATIC GAIN CONTROL,…Continue

A few weeks ago, I found some relatively cheap Chinese K3(S) IF filters on eBay. Since I recently purchased a K3 (with the new synthesizer), I was wondering if the offered 250 Hz and 500 Hz filters are any good. I ordered two of each variant and a 200 Hz filter from Elecraft, in order to have some comparison models. I also measured the filters that were already present in my rig and concluded which filter combination and settings are best in my…Continue

SETUP: an UltraPico Keyer, keys a 555 TIMER CHIP..from the audio output of the 555, an audio cable is attached and goes to the input of a laptop's mic jack input...the 555 time chip sidetone is very rough sounding with lots of high pitched harmonics and key clicks...INSTEAD of trying to filter the 555's raspy tone, this video demo's using TRIGGER…Continue
SEREN - FULL MESH, P2P AUDIO, FULL DUPLEX, HIGH FIDELITY, with adjustable bit rate..mono or stereo....using the OPUS CODEC

this video demo's 3 cw ops transmitting over MUMBLE, in the same channel, on iCW at the same time and yet on the receive side, each op's individual audio stream is able to be controlled using this experimental setup using all free software.
EXPERIMENTAL TEST SETUP
3 different cw ops are sending at different speeds and different pitches…

2 low bitrate codecs are compared for how well they sound transmitting CW AUDIO TONES over the internet(FLdigi)...and then how well they do when their original low bitrate cw audio is regenerated using all free software vst plugins
here is a snapshot comparing the original waveforms of the 2 low bitrate codecs:…Continue

This video demonstrates an A/B comparison of transmitting morse code audio tones over the internet using a NINJAM SERVER, where the CW audio quality is usually poor, with lots of pops and clicks...however, if you use the original audio from the output of the NINJAM CLIENT, and divert it first to a software APPLICATION in order to regenerate the…Continue
This video demo's how to create a TEXT TO MORSE CODE MIDI FILE - to use for training in QRQ CW COPY. REAPER is the main APP for playing the morse code midi file. This method allows you to choose the CW PITCH, the VOLUME, the SPEED, THE RISE and FALL TIMES of the CW EDGES.. Some more advantages of using a MIDI FILE instead of an audio file for…Continue
