Are you looking for an off the shelf amp or a kit/project of sone sort?

Had the mad idea of using a combo of a RTL-SDR rx dongle and a HackRF (for tx) with Remote SDR as my rig.

In theory this is possible as they document here https://f1atb.fr/index.php/202.....-sdr-v3-2/ but I think I need a RF amp and (most important) a bandpass filter on the output of the HackRF to properly use it.

Anyone any recommendations for RF amp options (max of 10W for 2m/70cm) for this that would be property compatible with the conditions of a Foundation licence?

I'm leaning towards the conclusion that this is a bad idea, but wanted to see if it had legs.

Does anyone have an archived copy of this talk?

The episode demonstrating how to communicate with an Amateur Radio satellite was quite fascinating to see.

Got me wondering if some of what they to do to re-orient the antenna they were using could be automated or whether a different antenna design would alleviate the need for it. Deffo one to binge on at the weekend 🙂

In it he explains the origins of electromagnetic interference and how to minimise it. It illustrates every step with oscilloscope displays all with a practical approach.

He produces a monthly (or so) newsletter which is aimed at the embedded systems developer but it often contains hidden gems of instrument reviews or useful software - see http://www.ganssle.com

Vincent and Steve will be on hand afterwards for any difficult questions (provided they’re easy).

With the Steppir approaching 15 years old and needing some attention, maybe its time to look at a comparable replacement !

Join us for a very entertaining and informative evening with no other than Callum M0MCX, DX Commander - a YouTube celebrity no less.

Callum will be talking to us about how he designed and made a multiband vertical antenna, explaining how it works, and what kind of performance to expect. A multiband vertical antenna can offer great performance with a very limited footprint, and with the added versatility that it can operate on multiple bands.

Tuesday 11th May 2021, 8pm BST (which is 1900 UTC)

This event is hosted on Zoom:
