Spota-labs.com News

Collaboration with Paul, VK3HN, has resulted in several hardware projects related to SOTA and POTA. It is time to publish them on a website spota-labs.com

The name SPOTA stems from the development of a single-channel CW transceiver. My question back then was: How do I manage to get into a QSO on a fixed frequency? The answer was simple: by getting a „spot“ via my beloved SOTA or POTA—or „SPOTA“ for short.

The SPOTA-LABS project began when Paul (VK3HN) asked—kindly yet persistently—about the development status of my SPOTA ONE. I had actually already abandoned the prototype, as the prospect of building it using „Manhattan-style“ construction (without a printed circuit board) held little appeal.

A friendship quickly developed following our initial contacts. Paul is highly experienced in PCB design, and this opened up a whole new world for me—marking a major milestone in my history as a hobbyist.

That is how our first joint project SPOTA ONE came to be.

This site serves solely to document our DIY projects. There are no commercial intentions whatsoever.

I made 5 of those VK3IL keys and they are mega. I like this one too!

I like the photo of Spota Two. Here’s my latest prototype:

Hello Richard,

It’s great to read that you made all contacts, —especially the ones with us— using homebrew transceivers. That motivates me to use my own gear more often. Our next project is supposed to have a VFO (hi), so I’m sure it’ll work out.

By the way, there’s some news over at spota-labs.com.

There is an update regarding the development of the SPOTA TWO for the 60/40/30/20m bands, covering both SSB and CW modes.

Below is a test of the audio quality using various settings for passband tuning and filter bandwidth with and without the PA.
