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.
All the serious DXer's I know moved on to more modern technology years ago.
I personally use a Sony MiniDisc that is quite fantastic compared with a
tape recorder, but many of my U.S. DX buddies have moved further forward to
using MP3 solid state recorders with great results.

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.

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.

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.

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.
