[rec.audio.high-end] Needed: long recording times! Help

baxter@kuhub.cc.ukans.edu (05/08/91)

I have a Sony TC-758 10 1/2 inch reel-to-reel deck, which even Sony 
has been unable to repair (that in itself is a long story of 
incompetence on Sony's repair  facilities!).  However, I am looking
for something capable of recording several hours of music at a time
similar to my old Sony deck.

I have heard it mentioned that the relatively new Hi-Fi VHS video decks
record the audio track multiplexed with the video, giving the audio tape
speed an effective rate of over 100 ips, and therefore good frequency 
reponse, wow and flutter and other paramenters.

Other than  using a Hi-Fi deck, I don't know of any other means (except
for another reel-to-reel machine, which are getting hard for the average
consumer to find and get fixed!) of recording > 2 hour programs.  Auto-
reverse cassette decks aren't satisfactory, since the deck always seems
to run out of tape and reverse right in the middle of the selection that
you want to keep.

Are there any suggestions to this problem?

A dat deck can record for 2 hours.  Some of them, using extended play
mode, can record for 4 hours.  In EP mode, you only get signal up to
15 kHz, but if you're recording from FM radio, the signal is
bandwidth-limited to 15 kHz anyway.

Perhaps if we knew how long a recording time you need, we could come up
with the perfect recommendation.  

If your purpose is the longest possible recording without a break, then a
Hi-Fi VCR, or one using PCM encoding, will give you 9 hours on a T-180
tape.  

If you simply want as much time as possible in the smallest space, I would
suggest 8mm tape, using the 8-bit non-linear PCM tracks; a single MP-120
cassette will hold 6 4-hour recordings, for a total of 24 hours.

It's surprising, but for some purposes a VCR is a much better audio
deck than any dedicated audio deck I know of.  I use my VHS Hi-Fi VCR
to do timed recording of of a 2 hour radio show every week.  I can fit
2 hours on a normal video cassette without even using the slower LP or
SLP recording modes and without going to a longer tape.  I can set up
the record time in advance and have recording start and stop without my
being there.  And the audio quality seems superb.

One thing I don't have though is the ability to direct tune to
different stations.  Right now, I can do timed recording, but only of
one station.  I wish there were an audio tape recorder that could
really do everything a VCR does for video -- store large amounts on 1
tape, do timed recording, and automatically tune to different
stations.  Does anyone know of such a thing?

I do much the same thing with a local jazz show.  Only that one is five hours,
sometimes stretching to nearly six.

"seems" is the operative word here.  The high S/N ratio of VHS HiFi is achieved
through the use of a very aggressive, high-ratio (about 2.5:1) compander.  As
with all companders, its action is sometimes noticeable.  But, for recording
from FM where the dynamic range is fairly limited anyway (much like tv audio,
though not quite as bad as that), it isn't bad.

A VCR all by itself could do this.  The FM broadcast band starts just where
the low-VHF band ends, so with a few mods to the tuner synthesizer and a 
different stereo decoder you could program FM recording into your VCR (assuming
that the stations you wanted were on the cable; but while we're dreaming, why
not add another antenna input, switchable via programming).  

I doubt anyone will ever market such a thing, though, because the market isn't
very large.  Most of the public does not perceive radio as a source of 
"programs" that happen at specific times; rather, it's aural wallpaper, to be
switched on and off as desired.  

But if you are willing to buy some additional equipment, you may be able to do 
what you want, even with off-the-shelf hardware.  There isn't (to my knowledge)
one single unit that will do what you want, but:  

	- There is at least one portable radio with the capability to switch on
	automatically at four different times (one-day, four-event, in VCR 
	terms), with a different station and different duration for each time.  
	It's the Sony ICF 2010, a shortwave portable -- but it includes FM 
	(mono only).  On-time duration can be 15, 30, or 60 minutes.  

	- Several fancy component FM tuners have a "program" capability.  The 
	stations you want to record in sequence must be among those stored in 
	the tuner's presets.  You push the "program" button, then push the 
	preset-recall buttons in the desired order.  You then put the tuner 
	into "auto" mode and plug it into a timer.  Then, each time the timer 
	supplies power, the tuner advances to the next preset in the program.  
	At minimum this requires you to buy one of these tuners, plus an 
	outboard AC timer.  

	- The "outboard AC timer" could be an X-10 appliance module and timer
	controller; the timer controller provides two "on" and two "off" times
	per module ID (one-day repeating, two-event).  Or, if you are into 
	home automation, use the X-10 computer interface, which can store LOTS 
	of on/off cycles (7-day, 255 events).  Or it could be an "audio 
	timer".  Lots of manufacturers used to sell these.  Essentially this is
	just a digital alarm clock in a cabinet that will fit with a stack of 
	audio gear, and controlling a switched outlet rather than a buzzer.  

	For both the "programmable" tuner and the timer, check your local used 
	audio equipment dealers.  My JVC tuner does this, and I have an Akai 
	audio timer that has a seven-day, four-event program capacity; it cost 
	me all of $95 used.  Also, an audio timer shows up in the DAK catalog 
	every now and then.  

	- I've seen several JVC VCRs with back-panel AC outlets that can be set
	to be switched on and off along with the rest of the VCR, rather than
	staying on all the time.  This would obviously provide the most 
	convenient way to use a programmable tuner -- program the station 
	sequence into the tuner, program the VCR with the start and end times, 
	and plug the tuner into the back of the VCR.  If you're contemplating 
	buying a VCR anytime soon, you might look for one with this feature.

Another idea for recording FM broadcasts to VCR from various stations at
various times is a programmable remote control.  You've seen the generic
remote control units that can control 5 or whatever remote control devices.
I've heard of at least one that can be programmed to generate controls signals
at specific times.  So, as long as you have a tuner and VCR that can be remote
controled, your problem is solve. (with a small investment)

A more sophisticated solution is to use a micro computer to generate the remote
control signals.  I've heard of devices that you can connect to a personal
computer that can learn and send any remote control signal.  Then program
the computer to command your VCR and tuner to do whatever you want.

One option would be to find one of those universal remotes that can
be programmed to send out a sequence of commands at a given time.  You
could have it turn on the tuner, set the station, turn on the VCR, start
it recording and there you have it!  Of course, this would require a
tuner with IR remote control.  It would also require the universal remote
to be able to send out sequences of commands from mixed IR sources
(although, if that weren't possible, I suppose you could have it send
out the tuner commands at one time and the VCR commands a minute later).

I *think* universal remotes like this exist and shouldn't cost much more
than any of the other things people have suggested.

Good Luck!
