For SLIP to be useful, you would really want a multitasking OS, wouldn't you? Unless you made a SLIP TSR thing just to run a telnet or ftp daemon (although you'd still need a multitasking OS if more than one person wanted to log in)... sounds like an interesting hack though, if just for the sake of a hack, but I thought hacks were supposed to be insant *looking* solutions to *real* problems...

I'd say "rather aggressive" is mild (:>). Not only is there bad spreading but (assuming your attenuation numbers are correct) your receiver gets to see +40+33-280+33=-174 dBm. Since the moon itself is about 200 Kelvin at 10 GHz (though with only a 33 dB gain antenna it will not fill your aperture) and if the receiver has a 1 dB NF you get about 0 dB C/N in 1 Hz of bandwidth. Shannon has to be reckoned with and I'm afraid you are now about 7 orders of magnitude away from a goal of 10 Mbps.

It has two modems 1200 baud and 9600 baud. You can operate both at the same time and it does have the ability to operate as a KANODE with cross-banding. I have had mine for about a month operating 1200 baud on two meters and 9600 baud on 440. I am using it with KAGOLD software. I am very happy with the performance. I would recommend considering the 128K memory (approx $25 US) option if you need a large mailbox or several NUMNODES. 73, Bob -- ------------------------------------------------------------------- | E-Mail: bnovak@kaiwan.com | Packet: K0OK@K6VE.#SOCA.CA.USA.NA | ------------------------------------------------------------------- ------------------------------ Date: Fri, 30 Sep 1994 18:23:41 GMT From: ihnp4.ucsd.edu!pacbell.com!sgiblab!swrinde!howland.reston.ans.net!vixen.cso.uiuc.edu!uchinews!rover.uchicago.edu!frank@network.ucsd.edu Subject: operating system history..

Sad how history can get rewritten by someone who thinks their favorite OS was the first one in the world, especially considering 1/ The obvious 10-year chronoclasm between the emergence of RSX-11 and the emergence of CPM, and 2/ because CPM was a TOTALLY OBVIOUS port of OS8/PS8 from the PDP8, since the names, command syntax, etc were identical. (Come on, PIP, TECO (with another name,) ...) 3/ if you look at the Intel and motorola chip dynasties, you find 8088/80286/etc were early implementations of PDP8 micros, and CPM-DOS etc looked much like OS8.

Just thought I would throw my two cents worth your way I owned a MFJ-1270B which is the same as the 1274 without the tuning LED I switched to the KPC for taking on the road for size and pwr reasons . I would say that they are both excellent machines I had my MFJ for 4 yrs and it is now digipeating on a Hill in PEI. Now the choice should be made based on what you plan on doing with the tnc if you are only going to do VHF work with it then then the KPC-3 is the way to go . If you plan on dabbling in HF packet ax.25 protocol then get the MFJ . For the same price you get one mode on HF .
