To: ham-digital@ucsd.edu The receive audio is available unfiltered but buffered on pin 11 of the front panel control connector. The Mitrek *IS* a varactor-modulated radio. Just cut the lead feeding audio into the channel element (lift R505, as I recall), and shove the output of the modem into there. You can feed the TX audio into the unused pin 18 (the blank fat one) for a seamless installation. I have about a dozen of these in service in precisely this way. - Brian ------------------------------ Date: 15 May 94 06:40:29 GMT From: nntp.crl.com!crl.crl.com!not-for-mail@decwrl.dec.com Subject: Anybody use Mathcad?

We can't get our local X1J node to respond to a 'ping'. If I ping the next node down the line then the local node takes it and sends it on, the remote one generates an echo reply back to the local node which then does nothing. So the routing is mixed up somehow. The local node address is 44.135.128.6 and there's a route entry for 44.135.128.0/24 Port 0 (AX.25) Any 44.135.128.0/24 address is one that is local to the node (e.g. mine is 44.135.128.1). If the local node sees an ARP request for its address then it does respond to that. But anything else that it ought to send gets lost somewhere. What routing/arp entries are required to make the node spit out packets that are for local users?

Not sure I really understand your question Pete. I was having some trouble myself with some X1J stuff late last year. Turned out to be total cockpit error. A few you may want to add to your list is: 0.0.0.0/1 (to wherever your IP gate is) 128.0.0.0/1 (again, to wherever your IP gate is) Keep in mind that the X1J is not a full implementation of NOS. It won't ask for ARPs, nor can you ping it. There is just not enough room in the ram for all the code. If you are wanting something a bit more NOSish, try a Gracilis PacTen. We have one on our network and it is truly an amazing device.

I'd love to I have the MFJ1278B. This is the only TNC I have had, so I can't really compare. ST> "random code generator" (?) This random generator allows for practicing CW. I have never used it. ST>Is the MFJ fax really full-color, or is it "color shading" instead of gray? I think it depends on the transmission mode???? ST>How common are SSTV transmissions? Common enough on 14.230, if you are looking foor SSTV you will usually find some there. ST>Do most people find 18k to be adequate RAM? I assume this is on the mailbox? The minimal I got on the 1278B is plenty enough for me. I think it is 16K? Thats 16K worth of messages sent to your mailbox. Depends on how much mail you get and how often you want to review/delete your old mail. ST>Are there any features that make one unit significantly better than the othe ST>Are there any glaring problems with either? I have had some problems with the MFJ during Pactor, which is my favorite mode. The tnc will occasionally lockup. I seem to have more problems than others on the band during my links. So much of this may be from problems in my station setup, RFI etc. If I would have doled out the $59 for the MFJ program that supports the tnc I might feel better. The reason I went with the mfj was for sstv and not having the supporting program makes this almost impossible. I am trying to write some software to display the pictures myself, but it is slow going. If you get the mfj I would strongly reccommend getting the supporting program. It is an extra $59 but will allow you to receive sstv/fax with real-time display. Reports on the rest of the mfj terminal program I have heard are not too good. But you can use most other shareware type software for packet/p[actor/rtty/etc. To date I have not seen any software that supports the mfj sstv/fax modes. I have used LanLink for the other modes, and it supports the mfj very well. My packet reception on 2 meters is not as good as it should be. I only receive packets if I get a full scale signal. My 2m reciever has 5 bars indicating signal strength, and I do not receive good packets if only two bars are lit. I think this is more a problem with my tnc than with mfj tnc's in general, since another ham I know, who has an mfj1278 (no B) told me I should be recieving packets with that type of signal strength. I have talked with mfj tech support about 3 times. Once was on the lockup problem and they immediatly sent me a revised eprom, no questions asked except for my mailing address. I received the new eprom about 3-4 days later. I had to ask twice for specs on the sstv formats for writing my own p[rogram. I think the first request which I made at the same time as the eprom revision got lost. The second request was responded to promptly. I received a disk within a week. Overall I would rate the dealings I had with their tech support as excellent. It is hard to get through to them at first, (phone busy, 800 number always busy) but once I did, they took care of me. ST>better designed TNC, with a lot of support from AEA and amateurs. He ST>claimed the filtering and reception on the PK-232 was superior to the ST>MFJ. There are a lot of PK232 users out there I have linked with. Very few mfj users. I have linked with about 5 - 6 mfj 1278b hams. If I remeber right, they all reported the lockup problem in Pactor similiar to mine. This lockup is more frustrating than devasting. When it happens, I turn the tnc on/off, re-enter my callsign, and re-link. I don't know if the AEA has a similiar problem. Didja look into the KAMS at all? Reports on the new GTOR mode sound really good. I dunno if MFJ or AEA are planning (or even can if they ant?) on adding this mode or not?
