Notes on JS8Call

My best friend KX0U invited me to JS8Call. This is my project to get there. OH, and thanks Jim! Equpment Starting from the computer end, I’m using [Dragon OS] (https://sourceforge.net/p/dragonos-focal/wiki/OriginStory/). More on it latter. The computer is connected to a Xiegu DE19 interface. I tried using a DigiRig with much frustration. More on that latter. The Radio is a Xiegu G90 controled by flrig. JS8Call is connected to flrig. My antenna varies between DX-Comander virtical and # QRPGuys Portable No Tune End Fed Half Wave Antenna. »

Going DMR

Not your father’s radio! I’ve started with a couple of new radios for this round of Ham Radio projects. A Radioddity G90 and their GD-88. As a fan of SDR, I’m using digital modes with both. FT8 on the G90 and DMR on the GD-88. I love the way FT8 cuts through the noise when signal are low. But I can’t yet say I’m a fan of DMR. It seems like a radio build by a government committee that didn’t know anything about it. »

AM broadcast band filter

For the W5TSU.net:8030 receiver I build a broadcast band filter. This should front end overload and intermod created by these stations and allow for better Ham band receiption. I also wanted to learn how to build my own coils. I found a design at the vk3il blog. This filter was modeled with the ELSIE (free version). It is a 7-pole Chebychev filter with cutoff frequencies of 1.7MHz. I started by winding some coils from 22, 26 and 30 awg magnet wire. »
