Elecraft K3(S) IF filter study - OEM vs Aftermarket

Hi everyone,

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…

iCW - 2012 - How to send morse code over the internet on WINDOWS 7 : THE BASIC SETUP

LIVE RECORDING of a QRQ CW QSO - MORSE CODE OVER THE INTERNET - from 2009

Using Mumble( open source skype like voip program )and FLdigi to communicate morse code over the internet. LIVE RECORDING from 2009. [ Missouri to Michigan internet path ]

SETUP: using a virtual audio cable, we connect the output of FLDIGI to the input of MUMBLE. We both connect to a MUMBLE SERVER and instead of using MICROPHONES, we send morse code audio tones at high quality, high fidelity, and low latency, to each other. The audio is FULL DUPLEX and allows for good QSK response during the conversation for breaking in.
