One Model 28 ASR Teletype, complete. Includes spare Model 28 RO less cabinet i.e. a spare printer mechanism with base. The 28 ASR has a regular friction feed platen. The 28 RO is equipped with a pin feed platen, vertical and horizontal tab kits (was used to print airline tickets). If you really want it I have the Teleticketer (tm) control box - essentially a 300 baud autoanswer modem with answerback and a loop current generator. This unit has been in storage in the back of my garage for the last 5-6 years when the current owner moved from a house into an apartment and asked if he could store it in my garage. I believe it was working at that time. He has since lost interest in it, and told me to get rid of it. Manuals _might_ be available - if any interest is shown, I will put the prospective buyer in touch with the current owner. -- Mike Morris WA6ILQ | All opinions must be my own since nobody pays PO Box 1130 | me enough to be their mouthpiece...

Having a broad-band front end the Rx overloads in some environments with strong signals, even with the rubber duck antenna! I don't really like the sliding cover for the keypad and I see that they have dropped the idea for the TH78 replacement that has just come out. I've played with the advanced features, but don't really use them. I find the tone burst operation awkward - I don't like the separate button and would prefer it on the PTT. I've been told that the speech quality is very good with the built-in mic, and even better with the SMC-33 hand-held mic. You can set it up so that the Rx covers 50 MHz up to 950 MHz, with scanner facilities, although this isn't in the manual. AM detection is provided for the air band. It even has a couple of games programmed into its ROM! 73, Leon -- Leon Heller | "Do not adjust your mind, there is G1HSM | a fault in reality": on a wall Email: leon@lfheller.demon.co.uk | many years ago in Oxford.

Production to begin in January. You are also right that another production run of the Sierra will likely take place in the future (according to Jim). I have already received confirmation of my Norcal-40 order.
