To: ham-digital@ucsd.edu Cleaning up the shack. I have two PSK modems for sale, as I have switched to a DSP-2232. ......................................................... PacComm PSK-1 modem. Interfaces to a TNC-2 modem disconnect header, and to many other TNCs with a bit of work. Suports 1200 baud PSK, as used on AO-16, WO-18, LO-19, FO-20, and IO-26. Decodes 400 baud PSK as used by AO-13 telemetry. Includes all original cables, connectors, manual, and separate RS-232 cable used for 400 baud telemetry. No power supply, but uses a standard wall unit. Excellent condition. $75 firm, including shipping. ............................................................ TAPR PSK modem. Interfaces to a TNC-2 modem disconnect header, and to many other TNCs with a bit of work. Suports 1200 baud PSK, as used on AO-16, WO-18, LO-19, FO-20, and IO-26. Includes all original cables, connecors, manual, TNC header disconnect, assembled in a Radio Shack box. Works perfectly, but in this case, beauty is in the eye of the beholded. $50 firm, including shipping.

To: ham-digital@ucsd.edu I'm fairly new to Pactor, but in observing the behavior of the mode on 80M, I've observed something which is kind of interesting. Occasionally on my own and on monitored QSOs, something disrupts the connection (which I understand is precisely what Pactor is supposed to get around, that is unreliable links). Then what seems to happen is that the two stations continue to transmit blindly, and the 'sending' station eventually times out, causing the need for a re-connect. Basically what *seems* to be happening is a total loss of synchronization, with neither station shutting up long enough for the link to get back on track. After a re-connect, things proceed smoothly. Another anecdotal observation (which may be entirely a factor of the sample being skewed): it seems most often to occur between two PK232 controllers. Is there any 'link recovery' protocol built into Pactor which should resolve this, or perhaps a tnc parameter setting that has been undocumented or overlooked? It strikes me that what sometimes happen is rather analagous to the packet collision problem, and might be avoided in the same way. Or is this a 'hole' in the protocol?

It seems to receive OK, and it will key the mike and send a carrier, but doesn't transmit the modulated packet signal. With a speaker connected to the TNC I can hear the TNC generate 'packet racket', but on a separate receiver I don't hear this 'racket', just the mike being keyed. I have 'jump L' installed but am thinking I want to put the capacitor and resistor in the cable instead. Should I use the same value capacitor as is on the MFJ board? Or is this the source of my problem (i.e. I need to use a different (smaller) resistor)? Or do I have a defective unit? Any suggestions or opinions would be appreciated. -- **************************************************************** *Bill Lindberg * **au919@yfn.ysu.edu***am257@freenet.hsc.colorado.edu***KC5FKN*** **************************************************************** ------------------------------ Date: 25 Apr 1994 14:42:19 GMT From: ihnp4.ucsd.edu!agate!darkstar.UCSC.EDU!news.hal.COM!olivea!news.bu.edu!bloom-beacon.mit.edu!senator-bedfellow.mit.edu!agray@network.ucsd.edu Subject: Internet Radio - Dominican Repulbic To: ham-digital@ucsd.edu Can anyone tell me how feasable it would be to use packet radio??

To: ham-digital@ucsd.edu Hello. Thank you for reading this posting. I have just begun to play with the "901130" version of KA9Q's NOS and I am wondering if it supports the use of dual-port tncs like the KAM and KPC4?? If so, how can I get NOS to recognize and use both tnc ports at the same time?? If you have any advice for me, please send internet e-mail to me at RUMBALJ@GOV.ON.CA. Thank you.

To: ham-digital@ucsd.edu Hello. Thank you for reading this posting. I need help in getting a KAM (or KPC4) connected to my Icom W2A dual-band handheld. I have a cable already made up that allows me to transmit but I am having tremendous difficulty finding a configuration that will allow me to receive. The problem only exists when I try to use the KAM-W2A combo on 2m. The system seems to work OK on 440 because the PTT line goes to jack SP1, while the audio is taken from jack SP2. (This is not possible on 2m, though.) Although specific instructions are desired, any general advice is also welcomed. Please respond by internet e-mail to RUMBALJ@GOV.ON.CA.

Most of these stations are closed BBS stations handling traffic but 14.103 is used for calling and QSO's. Also look around 7.095 to 7.110 and 21.095 to 21.110. 73 John ============================================================= John Boudreau VE8EV INTERNET: ve8ev@amsat.org Inuvik, NWT, CANADA PACKET: VE8EV@KL7GNG.#NAK.AK.USA.NA ============================================================= ------------------------------ End of Ham-Digital Digest V94 #129 ******************************
