I probably should have asked for this before I bought one.
I bought a Sony at circuit city for 24bucks. It seems to work ok but I don't think the quality is so good. I opened her up and poked around. Real cheezy. I'll be leaving this in the desert out in California along with my truck full of camping gear and a couple of loops. I'm flying back and so I'm ditching everything cept the radios and tapes and a few clothes. When I get back I'll probably buy another recorder so I am going to know what I should buy. I had to buy a damn 60db reducer to drive the Sony tape deck from my Degen that has a standard 1v output. Also I wonder if I should use 60min tapes or 120min tapes. 73 NEO |

I record at 22050Hz & mono, so it doesn't take that much space on the hard drive. Editing on a PC is quite easy with free software. |

UNless this is a portable application, surely the best solution is an actual cassette deck (if you really want to stay with tape). You get line inputs, with volume controls and no AGC. You get level indicators. You can select the type of tape (regular, CRO2, metal), and decide whether to use Dolby or not. The line output makes it easy to hook to your computer when you want to turn the tapes into CDROMs. SOme even do auto-reverse. They all have pause controls, letting you prepare for recording without letting the tape roll. The only disadvantage, other than size, is that they generally don't have a means of remotely controlling the motor, so it's messier to make it start recording at some specified time. And of course, few people are using cassettes anymore (I notice I'm not even seeing "Walkman" type portable cassette players at garage sales much, it's now progressed to the equivalent in CD players for only a few dollars), so they are plentiful at garage sales and rummage sales, and real cheap. I got one a few years ago, a dual deck, for all of one dollar. I brought home another one, it seemed a bit fancier, from a rummage sale when we were putting the boxes away afterwards; nobody had bought the two that were for sale. Since they are cheap, one could open it up and break the wire to the motor, bringing out the leads for remote on/off, just like the portable cassette recorders of years gone by. Most use a low voltage DC motor, just like the portable cassette recorders, so it's the same thing. I"ve bought long prerecorded tapes that have become mangled on some cassette players, so I wouldn't recommend 120 minute tapes. They have to make the tape thin in order to fit it all inside the cassette shell, and that makes it too fragile. I've never had a problem with 90 minute tapes, though. Michael |

Ok, thanks Misters Black & Miso. I'll grab some 90min tapes and plan on
using the pause control. Maybe next expedition I will have a laptop with me. I see how it could be very useful for logging, maps, pointing arrays, downloading porn, communicating with message boards, and a plethora of other as yet unthoughtof tasks. The problem for now is that I have to travel light and a laptop is just too much to have to worry about if vehicle breaks down and I have to thumb it. My only power is 12v cigarette lighter so I do have that limitation. I built a charger for AA batteries from lighter socket so that is all I have. 73 NEO Michael Black wrote: "N9NEO" ) writes: I probably should have asked for this before I bought one.

A laptop powered from a portable power supply on your 12V auto is QRM city. A laptop in it's internal battery is OK. One of my projects that I never get around to doing is to design a filter to use between the 12V from the car and the portable notebook power supply. Unless you have a late generation notebook, you can't get more than 3 hours of use on the internal batteries.

Ok, very good info fellas. I'll look into something a little more
permanent for the future. I like 1/4 speed option and hooks for the radio. As far as filter goes I would think an off the shelf EMI filter that you can get at digi-key might go a long way towards fixin noise from PC. There really isn't so much magic as all the filter designer guys say, but if you never designed one then you want to pay attention to the layout. I use store bought for my smps here in the shack, but design them for large motor drives at work. 73 NEO Bob Miller wrote: On 1 Oct 2006 11:45:37 -0700, "N9NEO" wrote: Ok, thanks Misters Black & Miso.

I don't know why you fella's are recommending old technology like a tape
recorder. It's like recommending to a fella that want's a new auto to buy a wagon like they dragged across the prairies in the old days.

I don't like recording in MP3 since ultimately I will have to edit the audio. If you transport the final audio in MP3, it means the audio has gone through compression twice. Generally that sounds bad. I record on a hard drive in PCM. For mono, 16bits, and 22050Hz (plenty fast for shortwave), an hour is around 150Mbytes. Considering the hard drive is in tens of G bytes, recording PCM isn't a big deal. I've also done stereo recordings, putting two different mono tracks on the same stream. In PCM, the channels will still be discrete. The same is true for Ogg Vorbis, if you really must compress while recording. MP3 Pro can do "dual mono", but I believe the free MP3 recorder codec blend the channels. "N9NEO" wrote in message ps.com... Ok, very good info fellas.

As far as filter goes I would think an off the shelf EMI filter that you can get at digi-key might go a long way towards fixin noise from PC. There really isn't so much magic as all the filter designer guys say, but if you never designed one then you want to pay attention to the layout. I use store bought for my smps here in the shack, but design them for large motor drives at work. 73 NEO Bob Miller wrote: On 1 Oct 2006 11:45:37 -0700, "N9NEO" wrote: Ok, thanks Misters Black & Miso. I'll grab some 90min tapes and plan on using the pause control. Maybe next expedition I will have a laptop with me. I see how it could be very useful for logging, maps, pointing arrays, downloading porn, communicating with message boards, and a plethora of other as yet unthoughtof tasks. The problem for now is that I have to travel light and a laptop is just too much to have to worry about if vehicle breaks down and I have to thumb it. My only power is 12v cigarette lighter so I do have that limitation. I built a charger for AA batteries from lighter socket so that is all I have. 73 NEO Couple of ideas -- C.Crane Company sells a cassette recorder that goes as slow as 1/4 speed, and has all the bells & whistles for recording from a radio output. It costs $100. Or, look at the little micro-cassette recorders that are frequently used for business purposes; they're quite small; I have an Olympus Pearlcorder S950; think I paid $50 or $100 or so for it. There's usually a pretty good selection of these smaller recorders at places like OfficeMax. The fidelity is surprisingly good, especially if patched into a bigger audio system. bob k5qwg Michael Black wrote: "N9NEO" ) writes: I probably should have asked for this before I bought one. I bought a Sony at circuit city for 24bucks. It seems to work ok but I don't think the quality is so good. I opened her up and poked around. Real cheezy. I'll be leaving this in the desert out in California along with my truck full of camping gear and a couple of loops. I'm flying back and so I'm ditching everything cept the radios and tapes and a few clothes. When I get back I'll probably buy another recorder so I am going to know what I should buy. I had to buy a damn 60db reducer to drive the Sony tape deck from my Degen that has a standard 1v output. Also I wonder if I should use 60min tapes or 120min tapes. UNless this is a portable application, surely the best solution is an actual cassette deck (if you really want to stay with tape). You get line inputs, with volume controls and no AGC. You get level indicators. You can select the type of tape (regular, CRO2, metal), and decide whether to use Dolby or not. The line output makes it easy to hook to your computer when you want to turn the tapes into CDROMs. SOme even do auto-reverse. They all have pause controls, letting you prepare for recording without letting the tape roll. The only disadvantage, other than size, is that they generally don't have a means of remotely controlling the motor, so it's messier to make it start recording at some specified time. And of course, few people are using cassettes anymore (I notice I'm not even seeing "Walkman" type portable cassette players at garage sales much, it's now progressed to the equivalent in CD players for only a few dollars), so they are plentiful at garage sales and rummage sales, and real cheap. I got one a few years ago, a dual deck, for all of one dollar. I brought home another one, it seemed a bit fancier, from a rummage sale when we were putting the boxes away afterwards; nobody had bought the two that were for sale. Since they are cheap, one could open it up and break the wire to the motor, bringing out the leads for remote on/off, just like the portable cassette recorders of years gone by. Most use a low voltage DC motor, just like the portable cassette recorders, so it's the same thing. I"ve bought long prerecorded tapes that have become mangled on some cassette players, so I wouldn't recommend 120 minute tapes. They have to make the tape thin in order to fit it all inside the cassette shell, and that makes it too fragile. I've never had a problem with 90 minute tapes, though. Michael |
