Orion 7000 the last Eddystone HF Transceiver

August 20, 2015 By: chris Category: News

orion7000 Seeing this Orion 7000 being sold for £326 on E bay recently brought back memories of the origin of this transceiver. In the mid 80’s we became aware that there was a market for a channelized HF transceiver with 100W output that could be used by non-governmental organisations (NGOs) in developing countries which lacked communications infrastructure. Customers would include aid agencies and medical help organisations. This resulted in the Orion 5000 which we sold very well all over the world. One factor was the channel restrictions foreign governments put on NGOs as to what frequencies they could transmit on and at that time synthesized transceivers where not allowed. Competition for this market was great with most of it coming from either the US (SGC) or Austalia (Codan). However typically we sat on our laurels and failed to see that these guys where developing synthesized products which could be set up on specific frequency channels. By the 90’s we were losing market share so quickly set in train the development of the Orion7000 which was a synthesized channelized 100W HF transceiver. Development took longer than we expected and by the time it was launched we had lost our major customer (ie the Red Cross). Soon afterwards the company closed down and the communications products were eventually sold to Ring Communications who probably sold off some of the Orion7000’s to the retail market. I used one once at a BVWS/NVCF do at the Warwick exhibition centre where I had managed to re-programme it to operate on the amateur bands. Using an SGC300 tuner and a long wire I had a few QSO’s at the show where Alan Ainslie was exhibiting some of his vast collection of Eddystone receivers.

Issues with the Gallery pictures

August 11, 2015 By: chris Category: News

An EUGer kindly drew my attention to an issue with the photo gallery in as much as the thumbnail for a particular set says that there are 4 photos but when you click on the thumbnail there is only 1 photo displayed. This looks to be a problem throughout the gallery and I will have to investigate by going back to the old site and seeing what is missing or wrongly described. It may take some time!.

UPDATE, within an hour of raising the matter with my ISP and webdesigner, those nice chaps at BarclayJames, the problem was fixed and I think we can now see all of the photos in the gallery. If anyone finds any more problems let me know and I will get it sorted. Chris G0EYO EUG Webmaster

 

 

Why a P.U. connection on a 888A?

August 11, 2015 By: chris Category: News

There is an excellent forum for vintage radio collectors and restorers called UK Vintage Radio Repair and Restoration which can be found on  http://www.vintage-radio.net/forum/ . I have no doubt many of you are subscribers to this forum. Recently, someone called “Carnival Pete “ (subscribers tend to use pseudonyms) raised the question as to why the Eddystone 888A Amateur Band receiver would have P.U. audio input. Subsequent discussion showed that this was a common feature amongst many of the Eddystone communications receivers viz; S.670, the 730/4 and the S.680/2A to name but a few. The collective consensus was that this was to enable the set to monitor sidetone transmissions from an co-located transmitter when in standby but that it could also be used in connection with a gramophone perhaps more aimed at the ex-pat market overseas. Also some Eddystone features just seem to be a standard. Perhaps because designs evolved from one to another. Interesting discussion.
