Brief History

Pulse counting superhet receivers were popular in the UK during the 1960/70 period and a number of articles were published in magazines, including ?Practical Wireless? and ?Radio Constructor?. These were ideally suited for home construction as alignment was minimal and no test instruments were necessary. Also as no IF transformers were used and most of the receiver worked at low frequencies, construction was straightforward. Added to this they offered excellent audio quality, unlike the super regenerative receivers.




A kit was also marketed by Sinclair and this inspired us to produce an up to date version of this kind of receiver.


After sales service

In the unlikely event you cannot get your receiver to work, we provide an after sales service. A standard fee of $9.95 is charged, which covers postage back to you and our repair fee.
