====== GM5ALX QO-100 Setup ======

My setup uses the Pluto SDR+ as the transceiver. It's one of two common setups, the other being upconverter from a 2/70 radio. 

Here's the overall diagram:

Also includes my estimates of the power. In operation I've found I'm at 85% in SDR console, which I think is circa 10-12W out, and I'm similar signal strength to the centre beacon. I've spoken to others with 1.2-1.8m dishes and they use 2-5W.

Here are a few construct photos:

Some optimisation possible. Dish is probably an overpriced one.

===== Software =====

[[https://www.sdr-radio.com/console|SDR Console]] is probably the best, if you run Windows, particularly for the geobeacon frequency locking. I'm meaning to write up my SDR console setup but recommend you read the docs, there's a dedicated [[https://www.sdr-radio.com/EsHail-2|QO-100 page]], and then YouTube.
