- Subject: APRS operations on 145.79???
- To: ham-digital@ucsd.edu
-
- Hello all,
-
- Recently, amateurs in the Omaha area where I live have been looking into
- getting an APRS network set up, and one thing that's been a concern of
- several people (myself included) is the fact that the "standard" frequency
- that is being used for APRS is 145.79 mHz.
-
- This seems to us to be much too close to the 145.80-146.00 satellite
- band, especially given the fact that APRS is designed for wide-area operation
- and people will probably be running some high-powered digipeaters, at least
- on a temporary basis for special events and probably on a permanent basis.
-
- It has also been mentioned that this frequency falls in a subband that
- has been suggested for experimental uses, and a permanent packet network
- based on established AX.25 protocols hardly seems experimental.
-
- What do you think? Are we being paranoid, or is it just that APRS
- isn't popular enough for people to have noticed? I'd like to see this
- discussed before people sart putting up fixed-frequency remote digis, etc
- that will be VERY hard to get moved. APRS looks like a great system, and
- I think it does need a coordinated frequency, but I don't think 145.79
- should be that frequency.

- To: ham-digital@ucsd.edu
-
- Serdar, a digicom modem WON'T work on a phone line. It is
- only for sending and receiving packets from a radio. It has
- no onboard processor to execute any commands. It will
- not work with the usual communicatios software on a PC, like
- Procomm, Telix, etc. It needs special software to operate.

- Subject: Help w/MFJ-1278 probx?
- To: ham-digital@ucsd.edu
-
- I have picked up a 1278 which has problems--I can talk to it but it
- doesn't seem to want to communicate out the far end. I can talk to its
- monitor program to change settings, using an IBM clone and ProComm, and
- I can even tell it to type out morse code, so the communication between
- the unit and the micro is okay, it seems.
-
- However, it I tell it to connect to itself, as per the manual's checkout
- instructions, it gives up after a few tries and says it can't find
- itself (that is, MYCALL is WB8VNV and "CONNECT WB8VNV" ends with "Too
- Many Retries"). Since it's used, I -think- but can't be -sure- I have
- all of the jumpers, etc., correct (note that the checkout procedure is
- done -without any connection to the radio-; it's an internal
- "connection").
-
- The ham I got if from is hard to get hold of (-: (no, he's in and out of
- town on business, that's all), so can anyone give me pointers of what
- jumpers/settings I ought to recheck as critical? I've been through the
- manual so many times my eyes are glazed over.
-
- How is MFJ about servicing these--as good as TenTec?
-
- Many thanks for any help.

- Normally you would mix a LO with the ~ 300 khz to get say, a 50 khz IF,
- then use something like a EXAR 2211 FSK demod to recover the data.
-
- Or, use a phillips 615 (NE or SA) to do the mix, lo, and demod, all
- on one chip.

- Subject: Problem using Tcp/ip mailboxes from internet
- To: ham-digital@ucsd.edu
-
- Hello. I am on a 386 Bsdi 1.0 unix box using vt100 terminal emulation.
- The system I am using used to be under System V and there were no
- problems with telnet to places like wa7slg.ampr.org.
- Now, under Bsdi, however, when I hit enter I see the ^m. Also, when
- sending commands to packet nodes like the r command for routes I get an
- invalid command. I have a feeling that my enter and other commands are
- no longer processed right. Any suggestions? Thanks. 73

- Has anyone figured out how to connect a Baycom/Poor Mans Packet circuit

-
- I just finished building a Baycom modem for packet, and I'd just love
- to be able to use my portable, non-MSDOS compatible Model 100 as a terminal
- to at least receive those packets.
-
- Actually, we've been trying to get the Model 100 to decode the signals directly
- through the cassette port. All we've been able to do is CW so far. RTTY
- is next, unless someone has cracked that nut already ...
