Personal Firewall Reviews
"The perfect personal firewall would be inexpensive and easy to install and use, would offer clearly explained configuration options, would hide all ports to make your PC invisible to scans, would protect your system from all attacks, would track all potential and actual threats, would immediately alert you to serious attacks, and would ensure nothing unauthorized entered or left your PC." This great definition is quoted from Make Your PC Hacker Proof, Jeff Sengstack, PC World, July 21, 2000.

Remote CW with RKI 1.05 and Sparkfun FT231X breakout board

I've created a workable solution for sending CW via a "straight key" to my remote Flexradio 6600 at the lake using RemoteKeyerInterface (RKI) and a simple Serial/USB circuit.   RKI is only available for Windows. RKI enables you to use paddles or a straight key to send CW through a remote Flex‑6000 transceiver.  After several iterations I've settled on a design using the Sparkfun FT-231x breakout board and RKI v1.05 that was originally posted by Gary KT7AZ on the RKI  groups.io forum .   However, to send CW reliably via a straight key - there were two main problems I had to solve. First,  I had to resolve the network latency and buffer bloat in my shack's network by setting up a router with Smart Queue Management.   The Ubiquity EdgeRouter  was recommended by a friend of mine (Larry N1FG) and has been working great.  I'm using the 4 port Edgerouter X which was only $50 at microcenter (open box special).  No more audio stuttering or dropped packets, which kills

 Love my Wolf Rive Coil Antenna for POTA use but I haven’t marked it up (yet) to facilitate quick band changes while out in the field.   Here are some notes to use as a starting point based on the work by W0DHZ Dale Henninger: 102″ Telescoping Whip Band Whip Length Coil Position 6m Only 1st section of whip extended No Clicks – Top of Coil 10m 3 sections out + 6″ of 4th section No Clicks – Top of Coil 40m All sections out 3 Fingers Down 213″ Telescoping Whip Band Whip Length Coil Position 10m 8 sections out + 1″ of 9th section No Clicks – Top of Coil 20m 9 sections out + 13″ of 10th section No Clicks – Top of Coil 40m All sections extended 16 clicks down Reminder to subtract the length of the Wolf River Coils SB-1000 coil from the 1/4 Wave lengths above. http://www.w0dhz.com/wp-content/uploads/2021/08/WolfRiver-SB1000-213inWhip-Tuning-Spreadsheet.pdf
