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

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

April 13, 2020 By: chris Category: News

Gerry recently spent the evening checking out anew antenna with my Eddystone S.940, recently brought out of ‘mothballs’ in the garage. The receiver was giving a good account for itself on the 50‘ of wire but he noticed a few problems with the BFO so decided to give it the once-over and has written account for you all to read Eddystone S.940 Revisited

 

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.

April 07, 2020 By: chris Category: News

Gerry has written a follow-on article on the restoration of his 2006 piece on restoring an S750. Shortly after restoring the S750 he obtained a replacement cast front panel which he eventually had sand blasted and powder coated. Finding a fault on the S750 he decided to replace the front panel whilst he was repairing the receiver. You can find the article here Eddystone 750 Revisited 2020

 

 

New EC10 Mk1 dial scale artwork in Restoration folder

March 20, 2020 By: chris Category: News

Richard G8MWQ has been restoring a recently purchased EC10 Mk 1 which was in a pretty poor state. The first thing he noticed was the frequency scale was badly damaged. There were sufficient markings left to allow him to redraw the scale using a software package called Eagle CAD. The redrawn scale was mirror printed onto a piece of Inkjet Printable A4 Clear/Transparent Vinyl Glossy Self Adhesive Sticker from Amazon, this was then attached to the rear of the original glass (after cleaning off the remaining silk screen print), Richard attached the PDFs to a recent EddystoneUserGroup forum e mail so I have added them to the restoration section of the website. Richard say please make sure that when printed the horizontal scales are 250mm length. He also say that note, the writing is black which shows up remarkably well against the grey background, as CMYK printers cannot print white this was considered suitable. – Chris G0EYO
