More Operatics

Paul PC4T may be taking a rest from blogging but he is still active. Yesterday evening I spotted him using the new Opera mode.

Andy K3UK has prepared a quick guide to using Opera which some may find helpful. As he points out, Opera is not a QSO mode. The only information that is sent in a beacon transmission is your callsign. Other information that is displayed in the software such as QTH, distance and bearing is sent over the internet back-channel by connected software clients.

Eldon WA0UWH has taken the Parallax Propeller code from my previous post and tried it out on the air. He has already received several reception reports.

Before I can do the same I will need to build a small PA / LPF with an output in the range 200mW to 500mW. Hopefully I can find a suitable circuit that uses standard components such as 2N3904 or 2N2222 which I have in my parts box. Suggestions welcome.
