\"HRO-660\"<\/a><\/p>\n

SWLing Post<\/em> contributor, Dan Robinson, writes:<\/p>\n

Wow . . . a huge, amazing rarity…this is perhaps the rarest of radios, the HRO-600.<\/p>\n

It is almost never seen on the used market and when it is, it is usually in non-operational condition. In its day it was quite advanced, though now, a Tecsun could run rings around it, and it uses NIXIE tubes…good luck obtaining those…anyway for anyone who has never seen one in this condition, and for everybody, here it is…<\/a><\/p>\n

Wow–I thought that receiver might sit on eBay for a while, but it sold for $3,895 US only moments after Dan spotted it.<\/p>\n

Assuming this listing will eventually disappear from eBay, I downloaded a\u00a0few more photos:<\/p>\n

I really enjoy tips like this from Dan. \u00a0While rare radios like the HRO 600 are well<\/em>\u00a0beyond my budget, it’s so much fun to learn about them. Indeed, I had no idea HRO made a receiver that used Nixie tubes!<\/p>\n

What is a Nixie tube you ask? Per Wikipedia<\/a>:<\/p>\n

\"Nixie2\"<\/a>“A Nixie tube, or cold cathode display, is an electronic device for displaying numerals or other information using glow discharge.<\/p>\n

The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols. Applying power to one cathode surrounds it with an orange glow discharge. The tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon, in a Penning mixture.<\/p>\n

Although it resembles a vacuum tube in appearance, its operation does not depend on thermionic emission of electrons from a heated cathode. It is therefore called a cold-cathode tube (a form of gas-filled tube), or a variant of neon lamp. Such tubes rarely exceed 40 \u00b0C (104 \u00b0F) even under the most severe of operating conditions in a room at ambient temperature. Vacuum fluorescent displays from the same era use completely different technology\u2014they have a heated cathode together with a control grid and shaped phosphor anodes; Nixies have no heater or control grid, typically a single anode, and shaped bare metal cathodes.”<\/p><\/blockquote>\n

As Dan states, Nixie tubes can be very<\/em> difficult to source these days. I’m sure the radio collector that purchased this HRO 600 is well aware.<\/p>\n

Update:<\/strong> While I don’t know what Nixie tubes the HRO-600 takes, Leeds Radio<\/a>, has a substantial\u00a0collection of Nixie tubes at reasonable prices. Click here to browse through the collection<\/a>. Leeds, by the way, is a fantastic resource for pretty much any sort of tube\/valve you may need. Check out this piece on Leeds Radio\u00a0from WNYC<\/a>.<\/em><\/p>\n

I hope someone uploads\u00a0a video of the HRO-600 in operation; I’ve never seen one in action.<\/p>\n

Dan, thanks again for sharing your eBay finds!<\/p>\n","protected":false},"excerpt":{"rendered":"
