Don't throw your old Android phone away, but give it a new purpose by using it as an antenna rotor controller with Visual Rotor and the Android app. All based on an Arduino Mega 2560, with some "easy to get" hardware.

He received the first-ever WAS for (902 - 928 MHz). His station consists of a 5-meter dish with 400 W of power obtained from two 300 W Motorola amplifiers in parallel.

"The Signal One 1030C. Probably the rarest & most expensive transceiver ever made. This one came in as a basket case. Rebuilt pretty much every circuit & power supply. Works beautifully now. Supposedly there were only 6 of these made and it is not for sale."

What was the last radio that YOU bought?
For me, it was upgrading my Anytone 878UV Plus to the ii version about a month ago…And I absolutely love it… Amazed at all the things it does both digital and analog… 5,000 memories...What about you? What's going to be your NEXT radio?

Remember when call areas used to matter? Back when you had to change call signs if you moved from one area to another… Back even when you operated outside of your main call area, you had to add /(new call area number) to the end of your call… I do not miss those days at all!

75 today. 3/4 of a century. Over 60 of those years as a ham. Every one of those decades as a ham has been increasingly more fun, more interesting, more motivating, and more intellectually gratifying. YMMV – but from my perspective, this hobby is more exhilarating than ever! K3RRR

I have owned a LOT of radios from ALL FOUR of these companies. I personally think the labels are WRONG on these pictures and that Icom and Yaesu labels should be interchanged.
What changes would you make to this graphic based on YOUR experiences with these radios?
