MODULAR construction of transceivers is standard nowadays.  But cast your mind back to the 70’s (if you can) and the modular layout gracing the Atlas 210x would have been nothing short of revolutionary, as radio equipment of that time often had truncated wire runs, which made servicing a rig a veritable nightmare!

The Atlas 210x:  a sound little transceiver

if ever there was Capt!

This Atlas 210x had been to the African savanna, so was a bit battle-scarred

So the Atlas 210x was not only a great little rig for non-tech people, but was also an excellent learning tool for radio engineering students, as well as aspiring radio amateurs –yours truly included. We could not pop out a faulty board, repair it and pop it back in again – job done!

Modular design made everything look so neat, so it’s not hard to see why it caught on

What surprised me when I gave the Atlas 210x a go is the sheer clarity and sharpness of the receiver board, with sharp-edged reception and S9 signals on the 80 metre band, with very little QRM (interference).

If only life could be more like this!


All in all, given the age of this little transceiver, I found it a joy to operate, with good QRN rejection.  My only qualm was the tuning drive mechanism, which really belonged to another era.

One of the features of this little transceiver is that it boasts really beefy RF power transistors.  I was really impressed to see the RF power meter registering well over 100 watts on side-band, even on the higher frequencies. This was a boon when operating mobile, especially on 80 metres, as my signal was able to emerge a few S points above the noise.

The RF output stage is very easy to access by unscrewing two screws and hinging the panel down to reveal the circuit

It’s only my view

The Atlas 210x is a fantastic little transceiver, which in the ideal World, would have progressed to a new generation of Atlas modular radios, incorporating digital signal processing (dsp) and many other marvellous refinements that are today commonplace. 

Sadly, for Herb and many investors, those eagerly anticipated (and promised) new generation of radios never came to pass. 

They do say, however, that every cloud has a silver lining; and as with many great inventors and innovators, their contribution to science and technology often goes unrecognised in their own lifetimes, and often for years thereafter.  Could this apply to Herb Johnson W6QKI, who, in the foreseeable future might be rightly recognised as one of the founding fathers of the modern modular transmitter receiver?

Time will tell…

Dear Visitors

I do hope that you enjoyed this feature on the Atlas 210x.  Should you have any questions about my Atlas transceiver, just drop me a line and I will do my best to answer you.

In the meantime, please may I impose upon your generosity by asking you to cut and paste  on to your social media pages, so that your family and friends can visit the web site and possibly contribute to it their scientific knowledge, ideas and stories.

I thank you
