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: https://sites.google.com/site/tomw4bqf/copyingcwover70wpm
using the iCW PRO MUMBLE SERVER:
a test was recorded where a remote laptop was sending CW audio tones from FLdigi, to the iCW PRO MUMBLE SERVER located in TEXAS...the K3S has its own computer and mumble client - to receive the remote morse code audio tones from the laptop, and convert them into a cw keying signal using one of the circuits mentioned in the link above... this video was just an experiment to see how well the K3S would key qrq cw using this method of remote cw keying over the internet. THE K3S sends back to the remote user the K3S MONITOR SIDETONE audio...the sidetone behavior of the K3S, closely matches its RF OUTPUT behavior, so it is very easy to detect any possible cw keying errors coming out of the K3S, or other things possibly going awry from the setup - by just listening to how your sidetone is sounding...if the sidetone does not sound right , the K3S RF output is going to mimic whatever is going wrong with the sidetone that you might be hearing... ie packet losses, packet delays will make the K3 key "funny"
text sent from FLdigi at 80 wpm was used from W4BQF, TOM's famous COPYING CW OVER 70 WPM article :https://sites.google.com/site/tomw4bqf/copyingcwover70wpm
using morse code audio tones from the remote user, transmitted to the input of their MUMBLE voice chat voip CLIENT, then being received on RIG's local mumble client/computer, which connects to the K3S RIG via the audio derived cw keying switch circuit
NOTE: all RF OUTPUT of the K3S during this test was going to a 50 OHM DUMMY LOAD
