This is the home page of Paul Young, K1XM. Here you will find various amateur (ham) radio projects.

SO2R Box Project

My current project is the YCCC SO2R Box (plus). SO2R stands for Single Operator Two Radio and is a method of operating contests where an operator improves efficiency by listening on one radio while transmitting on another. The schematic and parts list for the SO2R box is posted on the website. Other information, such as the PC board layout files and firmware are available and will be posted here. Source code will probably not be posted here but will be readily available - just ask.

Open Two Radio Switching Protocol

OTRSP is the protocol used in the YCCC SO2R Box interface. It is a simple serial protocol.  It is available for anyone to use.

Antenna Switching Projects

My home station has computer-controlled antenna switching. This has advantages over manual methods. The boxes I have built are not easily reproducable but I plan to publish information about them here - I haven’t gotten that done yet.

I also have a design and firmware for a box which can control 64 relays, 32 high and 32 low side from a serial port. It has a few nice features such as hot switch protection for the relays and the ability to use a different antenna for transmit than for receive. This may become a YCCC club project but I have not even tried to find out if people would be interested.

Contests

I operate many of the major amateur radio contests and some minor ones, mostly CW but occasionally phone.  I usually operate the CQ WW CW contest from outside the USA.

Other Activities

I enjoy photography, particularly underwater photography.  I have a website with more information on that and some photo galleries, www.underwater.org.

And I enjoy international folk dancing.
