[TenTec] century 22

[Rick at dj0ip.de]

Hi Ron
HNY (in advance).

I too liked the Argosy (analog - not digital).
But to be honest, my Argonaut 509 into which I addad a 9 MHz CW filter and mounted its AF filter inside instread of outside, OUT-PERFORMED the Argosy on receive on the low bands.  
There were two reasons for that:
1) The Argosy did not have that lovely "elevator" preselector that the two Argonauts had, and
2) The Argosy did not have an RF gain.

I solved that problem by adding a switchable RF Attenuator to it and used my tiny but super-good home-brew tunable 40m preselector with it.

People may wonder why I did not like the "D" version.
Simple:  Battery drain.  Most of my portable operation was off of a motorcycle battery.

73,

Really?  

I always thought the C22 was an Argosy without the 50 W "brick" (since it uses the Argosy case and front panel).  Never appealed to me, because I'd rather have an Argosy (525 or 525D), given the choice, so I never looked into it any further.

Might explain why the C22 wasn't that popular.

Whoda thunk???

The C21 was a superheterodyne with a 5.0 to 5.5 MHz wide IF stage, fed by the RF input and the crystal oscillator for each band, and a product detector on the AF board that uses the VFO as the “BFO” to carry out product detection. It is NOT direct conversion.

I had always assumed that the C22 was a repackaged C21 with digital display. WRONG!

It is indeed a direct conversion radio. It premixes the PTO with the crystal oscillator for each band and shoots the result (which is right on the revive and transmit frequency) right into a mixer which direct detects signals, then on to the AF stage! What a downgrade compared with the C21!

WHAT A DOWNGRADE TT made to produce the C22!


If you have a choice, get a C21!
