AOR AR3000AB
I'm reading about this receiver at Universal-Radio. My first question
is, whats the difference between a wide band receiver from a shortwave receiver? Does a wide band receiver offers more bands including CW? I notice that Universal-Radio is not carrying much of Drake and JRC shortwave radio like they use to. I can not seem to find any sites that sells them. I do not care for portables. I like desk top or base radios. If I decide to purchase the Satellit 800 Millennium, I may want to find another shortwave (or wide band receiver) that will have features that the Satellite 800 Millennium may not have. This way I could cover more. I like to stack up on radios. I believe they should all be squared off. With all buttons and headphone hole in the front. I do not have a lot of tolerance for odd shapes although the shape of the AOR AR3000AB does not look too bad. SR 73! |

Does a wide band receiver offers more bands including CW? A wideband covers more RF real estate than an SW receiver. SW is, by definition in the radio world limited to HF, 30Mhz and below. Down to about the top of the AM band. A wideband receiver will cover frequencies up through VHF, and often above. Usually continuously. Widebands will offer multiple modes of reception, including AM, FM and often both CW and SSB. So, you can definitely apply a single receiver for many more purposes using a wideband than a receiver limited to SW, but there are compromises in performance. The IF's in a wideband have to be pretty wide to accomodate some of the services found on VHF. VHF channels can be wider than the SW broadcast bands, so filtration in the IF has to work a lot harder to produce adequate selectivity for SW listening where the widest broadcast channel is less than 10khz wide. Most widebands don't do that well on HF and below for that reason. Those that do are considerably more expensive than a dedicated SW receiver. Still, there are some decent widebands for the casual HF user. Someone for whom SW is not a primary consideration. I notice that Universal-Radio is not carrying much of Drake and JRC shortwave radio like they use to. I can not seem to find any sites that sells them. Drake appears to be exiting the shortwave market. As have a number of receiver manufacturers. JRC, likewise, has limited offerings in HF only radios. For a solid performance oriented HF radio, you'd likely have to move to R-75, by Icom, AR-7030+ by AOR, or products by Ten-Tec, Yeasu, Palstar, which often receive high praise. Or one of the newer, and less well known rigs, like Elad. Or you could go to the Used market for some of the classics. I do not care for portables. I like desk top or base radios. I'm with you there. As are many here. Although I do have a number of portables. If I decide to purchase the Satellit 800 Millennium, I may want to find another shortwave (or wide band receiver) that will have features that the Satellite 800 Millennium may not have. This way I could cover more. Satellit 800 has been a topic of hot discussion here, triggering imperatives across the bandwidth. My own recommendation is to avoid that one. Much has been said about QC on this rig. Then, again, some users swear by them. You can usually buy much more radio for the money, if performance is what you seek. If you like large radios, with big sound, capable of housing a family of 12, you might like Sat 800. I like to stack up on radios. I believe they should all be squared off. With all buttons and headphone hole in the front. Then you'd definitely like the Drakes. I do not have a lot of tolerance for odd shapes although the shape of the AOR AR3000AB does not look too bad. It's not a bad performing radio, either. Just not something that I'd use for HF, at night, on a crowded band. SR 73! |
Hi Peter: I might get the Satellit 800 Millennium soon. I know it is
not a top receiver. But, I am sure it will go down in shortwave history. It's a lot of radio for that price and it is very attractive. I hope that Grundig comes to realize that people love big radios in the old fashion style, but with modern features. In fact I have the Sony ICF 2010, but I do not like the shape of it that much and the LSB/USB does not work well. Part of my rig set up, I like to operate a number of radios in a certain sequence. The radios have to fit all together on my table. Do you have the ICOM R-75? That might be my next radio! If I get the Satellit 800 Millennium, I'll let you know, maybe we could listen to a SW station at the same time and compare signals. I am in Queens New York. What state are you in?

I was wondering if anyone has had any good luck buying radios or radio
gear/equipment at state or fed govt auctions? I haven't been to any local state or fed govt auctions before,I was thinking about checking one out once in a while. cuhulin |

I can't speak for the AOR since I don't have one, but I do have the late, great IC-R8500 from Icom, and its 10.7 IF out -- the first one shared by the whole range of the receiver -- exhibits vastly different behavior depending on which side of 30 MHz you are on. Below 30 MHz, it is quite narrow, as in less than 20 kHz. Above 30 MHz, it is 6 MHz wide. AOR's behavior might be different, but it is true that any wideband receiver will deal with issues not directly related to shortwave, and therefore MAY be not the best choice. -- Eric F.

Peter,
What Hallicrafters models do you have?

I realize you didn't ask me,but since y'all are talking Hallicrafters
radios,I thought I would throw my two cents worth in.I own a very nice good working Hallicrafters S-38EB radio I bought for $4.00 (four dollars) about eight years ago at the Goodwill store that used to be on Palmyra Street in down town Jackson.It isn't for sale or trade,it's a keeper just like all of my radios are. cuhulin |
I was wondering if their was device that I could connect to a radio
while listening to the airwaves that will give me a video display on the receiving signal. Is their a such thing? SR 73! D Peter Maus wrote: Eric F.

There are a handful of wideband receivers which actually have HF adequate IF strips. Usually by dedicating separate strips to frequencies above and below 30MHz. R-8500 is one of them. R-9000 is another. And AOR makes a couple, both desktops, both expensive, one mountainously so. Of the widebands I've played with, AR-3000 (in two incarnations) being among them, I've only been impressed with AR-8600, IC-R8500 and IC-R-9000 below 30Mhz when compared to a dedicated HF receiver. The rest were simply too wide for decent HF work. I was not impressed. |
My Yaesu FRG-9600 has a video board in it that does just that....

I presume you mean to display a frequency vs. signal strength graph... the answer is yes -- they are called panoramic adaptors or panadaptors. A more general device would be a spectrum analyzer, used as a panadaptor. You can expect to pay about $1500 for a new one, and at least one is being made today. I bought one for about $100 and was only marginally satisfied. I bought a spectrum analyzer for $300 that does a much better job.

There are inexpensive (and some not so inexpensive) AM/FM stereo radios
available in stores that sell radios that have a sort of built in video display.But I think those are different from what you are talking about.I dont own such a radio as that. cuhulin |
Hi Eric: I am not talking about a signal streghth or SWR meter as most
radio will have. It more like a scope or radar giving pattern information on the reciving attena. I was wondering if there was a device that could tell you from which dirrection and pattern the signal comming from and how. In the Now Your talking Book, their is a diagram of attenas patterns. I thought their must be some kind of a device for giving this information. I've seen too many WW2 movies. LOL! SR, 73! Now, Eric F.

There are used Microdyne Spectrum displays floating around E-bay and other surplus sources but you do not want them for a HF receiver. They are made for real broadband applications in microwave Telemetry systems. You would have to do a major redesign on the RF and IF circuits to convert one to work with a HF radio and the CRT cost well over $1000, if you can even buy one now that L3-Com dropped the Microdyne products that supported their spectrum display. They go cheap, but they are no bargain unless all you want is the CRT and HV power supply. They require a couple amps on each of the 15 volt power supplies, and are made to fit in the older receivers as a plug-in, or in a rack mount accessories tray. They are not intended to be operated outside of an approved cabinet because the HV power supply is exposed on the Chassis, and it can kill. -- Link to my "Computers for disabled Veterans" project website deleted after threats were telephoned to my church.

I was wondering if there was a device that could tell you from which dirrection and pattern the signal comming from and how. No -- that sort of plot can be generated by a sophisticated antenna system along with an equally sophisticated radio, but to do it "automagically" would be a little more difficult. Now, someone could write software to electrically or physically turn a very directional antenna and generate a signal strength vs. direction polar plot -- in fact, something similar to that is done on antenna measuring ranges, but it is non-trivial and you couldn't listen very well while it did the plot. No, what I was referring to was a Strength vs. Frequency plot, along the lines of the two graphs you see in this image: http://www.dim.com/~efricha/wrdisplay.png In the Now Your talking Book, their is a diagram of attenas patterns.
