Default Re: Ekco A182 restoration. An Ekco vanity set?

Can anyone advise on how to make best use of the shortwave bands? My shortwave reception tends to alternate between periods of clear reception and interference that wipes out the entire band. Is this normal? Also, is a standard wire aerial ok?

Hi Gabriel, SW reception varies depending on time of day and solar flare activity that influences the ionised layers of the upper atmosphere. Higher frequency bands, 16-19m, are best during daylight and the lower frequency ones, 41-49m, during night-time. A directional loop aerial followed by a wideband RF amplifier is your best bet. These are directional and so can be rotated to null out local sources of interference (to some extent). You can buy commercial examples of loops, the best ones being quite expensive. Some of the cheaper variety work acceptably. Search the Forum since there has been quite a bit of discussion of these, also some homebrew examples. A long wire aerial will work; that's all I use most of the time but it really needs to be outdoors because indoor interference devices are now so numerous. Cheers, Jerry

In our residential area, I find a long wire too effective at picking up the switch-mode PSU interference field seemingly radiated from every house. As a result, I now always use a loop aerial, which is effective at rejecting the interference. Mine’s a commercial one (Wellbrook), but a search of this forum suggests various home brew types.

Paul Sherwin described the use of a ferrite rod aerial from a scrap transistor set: https://www.vintage-radio.net/forum/...read.php?t=579

Thank you for the suggestions.

I'm familiar with Paul's thread and I had enquired about it with Paul directly a few months ago. I'll build it, it should be easy enough. I just need to get my hands on a spare transistor radio chassis with SW/MW/LW so that I can use the parts (ferrite rod and tuning cap) I'll put a request out in the appropriate section.

I'd be interested to hear how well it works on SW since most of the projects I've seen have been limited to LW and MW. I did come across this one https://swling.com/blog/tag/ferrite-antennas/ but my feeling is you'd be better off with a mag loop, swmbo permitting of course! Jerry
