Congrats Ted!  Nice callsign.

Introduce Yourself / K6TET becomes W6SY
« Last post by TangoEchoTango on May 19, 2021, 10:03:59 AM »
My new call sign is W6SY.  But 'round these parts, I'll still use the TangoEchoTango handle. 

I figured I'd apply before they start charging application fees.  I got lucky in the vanity call sign lottery. 
What are you up to / I have a new antenna in the yard
« Last post by kn6koo on May 19, 2021, 08:39:18 AM »
I'm working on a radio project. So far I've added a new radio/antenna in my yard that is connecting to an east bay radio link.  Here's a pic of it and as I get it set up I'll explain more about it. We'll call this a "teaser" for now.

Do you think it would work with say a Yaesu 991?

Good point about cutting out the third party providers.  Where exactly do you go to to get the information.

What are you up to / FIO: USA Ham License Info
« Last post by TangoEchoTango on May 17, 2021, 06:05:00 PM »
FIO = figured it out

How to cross-match HAM license data downloaded from the FCC, to obtain county data of the licensee (useful for many state QSO parties) ... and to show which counties are adjacent to the county inferred from the licensee's zip code (useful for contesting). 

The important thing: I no longer need to ping a third-party provider's internet database to obtain USA licensee information.  I can download it direct-from-FCC from time to time and access it from my own hard drive, eliminating my dependence on third-party providers. 

Because >80% of my contesting contacts are USA, this eliminates 80% of my dependence on the internet.  I could operate from an internet-free zone. 

It ain't brain surgery.  Happy to share.

FIO means "Figured it out". 

I finally figured out how to write a C++ program, runs in TERMINAL on Mac, to control directly my ICOM7300.  My app is 100% pure bare-metal C++: no third-party software involvement at all. 

My homebrew logging program can now retrieve the transceiver's frequency directly (no need to type it in). 

Happy to share. 
What are you up to / FIO: Control WinKeyer
« Last post by TangoEchoTango on May 17, 2021, 05:52:44 PM »

Last few days, I figured out how to control my WinKeyer directly from my Mac, WITHOUT using third-party software to maintain the serial port connection.

As always, it was simple-yet-non-obvious: just had to figure out the right C++ abra-cadabra to make it work. 

I was always afraid that an OSX upgrade or other hardware issue would invalidate my ballet-dance among several applications.  Progress means, reducing dependence on others. 

I won't go into it here.  Reach out, happy to share. 
Any Adventures you and your radio have taken recently / Gave FT8 a try
« Last post by kn6koo on April 28, 2021, 05:44:37 PM »
My goal is to try a lot of things you can do in Amateur Radio.  I've heard a lot about FT8 and digital radio so I added WSJT-X software to an old slow Dell laptop I own and found a printer cable to hook up my Yaesu FT991a.  After searching for the proper settings I finally got the combo going and gave it a try. 

What really got me was if you go to and select "map display" in the text you see a map that shows all the activity on multiple bands using all kinds of "modes" including FT8.

From my first brief session on 20 meters @ 35 watts I found that my call sign and signal was captured as far away as New Zealand and Australia as well as all over the US and Canada.  There's a screen shot attached.  What you're seeing are all the reporting stations that identified my signal and call sign.

I think this was pretty cool with a home brew antenna in my backyard. I look forward to keep working at this.

Thanks for a nice meaty post. I for one plan to check a lot of your ideas as time becomes available.  I would like to add a couple of YouTube videos on CW that you think have good value. So if you have a chance add their URLs here and I will add them to the mix.

Again thanks for a great thread on CW!
