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.
Free after sales service
In the unlikely event you cannot get your receiver to work,
we provide a free after sales service. A postal fee of $4.95
is charged, which covers postage back to you by registered
air mail.
