Beware of being scammed when selling or buying Eddystone sets and parts

May 31, 2020 By: chris Category: News

In our For Sale and Wanted section we warn users to be aware of the danger of being scammed when buying or selling Eddystone equipment. It has been many years since we heard of anyone being scammed but it looks as if someone has recently suffered such an event. A genuine user requested, through the Wanted section, for Eddystone 750 parts and was offered a complete 750 for US$150 from the USA. The payment included shipping to Australia and payment was made via Paypal to someone of a different name to the seller (warning bells?). The seller sent a copy of the waybill which the purchaser now believes to be a fake. The seller is not answering e mails and the purchaser is trying to reclaim a refund from Paypal.  These are semi-sophisticated scams and given that any sale or purchase is done on trust they are easy to fall prey to. When purchasing from unknown or non-verifiable parties (callsigns are verifiable) always ask to see proof of the existence of the materials (lots of photos so not just “library” shots). Ask questions which only an owner is likely to know and of course deal through someone like Paypal where you can register a complaint, (not Western Union) and only to the account of the seller. If you have doubts ask on the Groups.io forum if anyone has dealt with that seller/purchaser before. As the innocent party says  “Caveat Emptor”.

Eddystone S888A Revisited by Gerry O’Hara VE7GUH

May 09, 2020 By: chris Category: News

Following a house move Gerry O’Hara VE7GUH got his S888A Amateur band receiver out of store and decided to give it the once over. When he bought it some years earlier from a UK ham he didn’t even give the set his usual thorough check-out as it was in very good cosmetic condition and performed well. As a consequence he never wrote an article on it for the Restoration section of our website. Well he has given it a thorough check out and written it for us to enjoy.Eddystone S.888A Revisited

Intended especially for the AC/DC sets model 670 and 670A . You will find this in the Technical/Service Manuals folder under Accessories.



Installing a 500kHz calibrator in an S940 by Gerry O’Hara VE7GUH

April 18, 2020 By: chris Category: News

Gerry O’Hara shows you how to install the 500kHz calibrator for an Eddystone 730/4 into an S940 he was working on. The S940 has reasonable scale accuracy, claimed to be 0.5% on all ranges in the specifications – sounds ok, but that’s 150KHz at 30MHz, so it would be useful to have a calibration signal (‘pip’) to inject when needed. 500KHz crystal calibrator in an Eddystone S940

My Eddystone S.640 Revisited – Gerry O’Hara VE7GUH

April 11, 2020 By: chris Category: News

Gerry VE7GUH has revisited his Eddystone S.750, article here, and while waiting for my next ‘customers’ radio restoration project to arrive, he was looking for another ‘distraction’ as he was holed-up in the house due to the Covid-19 virus like everyone else. Then he remembered that I he had come across a reproduction finger-plate and scale plate for my S.640 in his box of Eddystone bits and pieces while he was retrieving the powder-coated front panel casting for the S.750.
