I am interested in it!! You might call Universal Shortwave in Columbus, Ohio 1-800-431-3939 and ask if they have any used or reconditioned RTTY decoder cards or readers available. The cards can be plugged into an expansion slot on your computer. You can use a standard audio cable to connect your shortwave reciever which must be fairly decent, to the card. I got a used Universal M 1000 for $ 150. It decodes Fax, Morse Code and most common forms of radioteletype. There are also "dedicated units" which don't require a computer. But they do need a monitor or printer. Universal has a RTTY expert, who can give you advice over the phone. They can also mail out a used equipment list. You could also check any hamfests or shortwave stores in your area. And read the RTTY, Utility and Computing columns of Monintoring Times and or Popular Commmunications so you know more about the equipment that's out there. RTTY took awhile for me to get used to. So if you need any help, let me know. --- OLX 2.1 TD MSI HQ!

Basically what you have is a antenna used for listening, not transmitting as I first thought. 2nd, Yes a tuner would help for receiving by providing a resonant tuned front end for the untuned ant, etc. I would use a store bought type preselector which has a front stage amplifier, etc. 3rd a simple circuit would be a "T" network such as ; on the antenna side of the "T", a variable cap on the rcvr side of the "T", a variable cap in the middle of the "T", a coil, tapped to ground caps could be approx 250mfd coil approx 28uh or 2- 2 & 1/2" dia 6-8 tpi 5" long, top part to the "T" and tapped bottom end to ground. To use, set caps mid point, try various setting on coil, then rotate ant cap, and then rcvr end for max signal. let me know how you make out.... 73's larry..

I have never cuaght a German diplo station. I've tried listed channels with no success. I was wondering if you could describe to me what an ARQ-E/ or E3 station sounds like when they are in VFT. I know what they sound like in normal operation. Also, I would like you to try this frequency and tell me what mode you think this might be -if you can hear it, of course. 4.020.0 Mhz 0000-0900 UTC. I have tried every mode, I get a lock on using FEC-A 192, but everything is trash, I think the signal maybe tricking the M-7000 into sync. Let me know what you hear.

It's more or less impossible to do this with a Yes I have decoded them, but it's areal pain with out a tuning scope! I find that many of the VFT signals I encounter are either encrypted or impossible lock on to.

The quick brown fox routine is an old type tutor since it includes every letter in the alphabet. Stations you this string at the begginng of a transmission to calibrate their sending equipment and tune up transmitters. They are also used as a test tape that runs for a while so other adjustments are made. It also indicates to the receiver that the transmission is ready to proceed. 73's Paul... ___ X OLX 2.1 TD X "Somebody Get Me A Doctor!" : David Lee Roth 1979. --- Maximus/2 2.02 * Origin: Arcane BBS -- ...a nickel for the whole brain (1:167/116) --------------- FIDO MESSAGE AREA==> TOPIC: 205 RTTY Ref: C1A00000 Date: 01/03/95 From: MIKE BILOW Time: 11:02pm \/To: ANDY MOSS (Read 7 times) Subj: A silly question....

The characters "R" and "Y" in 5-level baudot code are inverses of each other with bit patterns of 10101 and 01010. Strings of "RYRYRY" were sent for tuning purposes, since the time spent averaged over two characters was as close to 50/50 split between mark and space as you can get. On a tuning scope, you would see a nice, straight cross while "RYRYRY" was being eceived. -- Mike --- Msgedsq/2 2.2e * Origin: N1BEE BBS +1 401 944 8498 V.34/V.FC/V.32bis/HST16.8 (1:323/107) --------------- FIDO MESSAGE AREA==> TOPIC: 205 RTTY Ref: C1A00001 Date: 01/02/95 From: DOUG AUGELLI Time: 12:43pm \/To: ROB KEENEY (Read 7 times) Subj: RE: HOKA CODE3 FOR SALE Hi Rob, Make sure you have a Stacks= line in your config.sys.
