Hi I'm pretty new to SW radio. Not even a year into the hobby. I'm getting more and more into looking around for obscure SSB stations and weak muddy stations.

Here's the radio I enjoy the most: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4673&item=57204600 58&rd=1&ssPageName=WDVW I know nothing about the seller, or the condition of his radio. It's a lifestyle choice - it's probably a little larger than the Sat 800, and weighs about 50 pounds. It has no memories - it doesn't even use a tuning knob. But it's great at digging stuff out of the mud and making it sound good. I've owned newer and more expensive military radios, but never a better performer, or one that was easier on the ears. It has sideband selectable sync detection, (They call it AFC) and a fancy AGC circuit that doesn't get easily confused. My other suggestion is smaller, more expensive, has convenience features and if you put in the right filters can sound almost as good - the AOR AR7030+ You'll pay about $1000 for a used one. I have one I set up as a "transportable" for camping trips and vacations. But for home use, if I could only have one, I'd go with a 550 - even if it was more expensive than the 7030. (and it shouldn't be) You might also consider an Icom R75. I've never tried one. Folks say it's a great radio, but to get them to work the way they're supposed to, you need to modify them with a couple dollars worth of parts. The idea people who aren't engineers can greatly improve a radio for pocket change is enough to keep me away. I'd revise my feelings if Icom incorporated the most common mods in the next batch they made. If you're interested in radios, a good book to get is "Shortwave Receivers Past and Present" by Fred Osterman. Universal Radio sells it. It has basic information and specs for hundreds of radios. But it's overdue for an update - many of the current model tabletops aren't in it. Good luck with your hunt, and if you end up with a 550, feel free to email me for tips on how to use the AFC and coherent AGC. It's actually quite easy, but I can save you an hour or two of guessing. |

Nice looking the 550. If it doesn't use a tuning knob, what is it scan only
or direct entry? Are they quality made? Never heard of Harris sorry to say. I wish I could buy them all. I appreciate the offer Mark, thanks. I switch around radios like every 2-3 weeks but this new remote for the R-5000 really is nice. Hard to put it down! I'm going to do some research on it. "Mark S. Holden" wrote in message ...

You push the paddle up to increase the digit it's under, and down to decrease it. For scanning, you'd hold the far right one (or the next to last one) up or down as you listen. It has a "fast" button so you can scan faster. I can go from one frequency to another known frequency very quickly. I don't like the ones without the 583 option. They use 10 position slide switches for tuning. Pretty clunky. Fortunately, most have the 583. Are they quality made? Never heard of Harris sorry to say. I wish I could buy them all. Most Harris radios are built for the government. They're built like tanks. The outer cabinet is roughly 1/8" aluminum, and most of the modules inside are individually shielded in aluminum that's about 1/16" thick. The car I'd compare it to would be an early 80's Rolls Royce. They are very reliable. I appreciate the offer Mark, thanks.

Hi Mark! How does the Harris 550 perform on MW BCB? Is it better than a Drake R8/8A/8B ? Thanks, Margaret |

There is some attenuation on the MW frequencies - If you'd like I can look up how much and what frequency it starts at when I get home. Otherwise, the AFC and coherent AGC work on MW. Coherent AGC takes the AGC reading through a 500hz filter regardless of what filter you're listening through. It also has 126 or 130db of dynamic range. (Haven't read the manual in a couple years.) I almost always listen in sideband mode because the AFC and Coherent AGC don't work in other modes. Coherent AGC won't work without AFC. For RTTY decoding, I got better results with the AFC turned off. One of the things I like about the Harris is the filters are kind of wide - but they have a good shape factor, so audio quality is good, but selectivity has never been a problem. On AM & CW you can choose between 500, 6khz and if you enjoy listening to hets in the background, 16khz. On Sideband it's always 3.2khz. The 550 comes equipped for ISB reception too. (Both sidebands with one coming through the internal speaker, and the other on terminals on the rear.) Let me know if you'd like me to check specs for MW attenuation or dynamic range. Regards, Mark |

Thanks, Margaret Hi It is the sort of radio you can listen to for hours at a time without listener fatigue. The manual indicates sensitivity is 1.5uv max for Am, and .35uv max for sideband. (at 10db (s+n)/n ) It just says sensitivity is reduced below 1.5mhz The radio has half octave filters on the input - a very quick Look at the schematic leads me to feel you could adjust or eliminate the attenuation by tweaking the value of a 470 ohm resistor. Dynamic range is rated at 125db. Near as I can tell, two of the keys to good audio quality are dynamic range, and wide filters with steep skirts. My AOR ar7030+ also has good dynamic range, and the sideband filter I use with it is a 3.24khz crystal filter intended for a Racal 6790/gm. It has a shape factor of 1:1.33 The radio reads it as 2.9khz. |

Mark,
I'd say they are probably as good as the Drake series. While we're discussing questions on the Harris 550 why don't you tell us which one you think *might* come nearer surviving an EMP attack! ;-) Al ============ Mark S.
