Regards, Steve Diggs --------------------- cut here --------------------- Heatherington WA4DSY 56KB RF Modem ---------------------------------------- GRAPES (a Non-Profit Volunteer Organization of Georgia Amateur Radio Operators) is selling full kits of the WA4DSY 56KB RF Modem for $250. The proceeds from the kits support our packet network building activities. You will need a transverter with a 28 MHz I.F. for the band of your choice, a case, connectors, power supply and frequency determining crystals. The printed circuit boards, documentation, State EPROM, support diskette and all other parts are supplied. The transverter chosen should switch as quickly as possible in the 5-15 msec range to be effective. We use the Microwave Modules MMt 432-28S units; however, these are getting difficult to find except as used ones at hamfests. The last few we purchased new were also pretty expensive ($389). We believe that their 220 MHz units were quite a bit cheaper, but we've never bought any new. On the hamfest market, we have been paying $125 to $185 for used, normally working units. Maple Leaf Communications (Bob Morton, VE3BFM) is shipping a 220 transverter which has good charactertistics and an even better price tag ($279). We have two of these units and they seem to work fine. Contact Bob at 705-435-0689 or RR #1, Everett, ONTARIO, Canada, L0M 1J0. The transverter must be linear as the modem has amplitude variations as part of the converyed modulation, which must be reproduced by the transverter. Usually any transverter capable of SSB operation is suitable if it switches quickly enough. We also sell a printed circuit board set that includes the State EPROM, documentation and support diskette for $110. Documentation sets are available separately for $20 and we have a VHS (beta by special request) Video tape featuring Dale Heatherington explaining the Beta modem design for $20. Doumentation sets are creditable towards the full parts kits or board sets and the board sets are also creditable towards the full parts kits. We pay U.S. shipping, however, we do require that the approximate difference between domestic ground delivery and premium shipping be sent in advance. Overseas second day air can cost up to $60 per kit! The kits weigh about 2.5 pounds each, and we can put 3 to 4 kits in a single box to save on shipping. Please send orders (a letter is fine) and your check payable in U.S funds to: GRAPES, Inc. PO Box 636 Griffin, GA 30224-0636 We're sorry but we cannot accept Purchase Orders nor Credit Cards.

To: ham-digital@ucsd.edu Due to a problem with the GPS receiver and on-board BASIC computer, the balloon flight was delayed for approximately 2 weeks. The new flight is scheduled for Tuesday August 30th 1994 at 2pm MDT. This balloon flight is rather unique in that it is a prototype concept when one of the first data acquisition system is sent to the Martian Surface. The general concept is that the balloon will become heated and rise during the daytime, and at night it will descend. Dragging behind the balloon will be a type of funnel to "suck" up materials off of the Martian surface. The materials will be analyzed by an on-board computer and then the data telemetered to an orbiting satellite which in turn amplifies the signal to be sent back to earth. The amateur balloon flight for this launch has on board: BASIC Computer for making temperature and pressure measurements TNC IC2SAT 2 meter transceiver TRW GPS Receiver for position fixes ARGOS Satellite Transmitter (TELONICS Model ST5) The payload was put together by Engineering Students at Utah State University.

I know there are a number of AX25<>Internet gateways in the states (found quite a number of them). I discovered also that once connected to these nodes I have access to hundreds of TCP/IP nodes. But... I can not see the trees through the forest anymore. There must be a number of gateways or TCP/IP nodes who give access to local DXclusters, if not via IP, then via a VHF or UHF port (if not linked through real IP ports)... So far I found cluster access in W5, KH6 and KL7 - land. I'm particular looking for DXclusters on the east coast, westcoast and midwest. But... any tips are welcome.

Regards, Steve Diggs, KB4ZTN -----------------------cut here ---------------------------- FT5200.9k6 Hola a todos...paso a detallarles la reforma para utilizar el transeptor yaesu en 9k6. De echo se trata de un dual bander, teniendo un buen desempe.o en 9k6, Ubicamos la patita 13 del modulo de recepcion (inmediatamente despues del filtro ceramico cf1001, este esta entre las patitas 10, 11, y 12 del modulo) y ahi tomamos la se.al de recepcion para VHF, luego buscamos la patita 27 (en este caso el filtro esta entre las patas 24, 25, y 26 ) y ya tenemos el audio para UHF en recepcion. Para transmosion tenemos un punto comun, que es la union de los preset que ajustan el audio de ambos transmisores...estos son vr1001 y vr1003, muy chiquitos y habra que tener cuidado al trabajar en ese lugar. Justo en ese punto le aplicamos no mas de 1 volt pep y no mas...con eso tendremos la desviacion justa. Si queremos tener mejor recepcion y la posibilidad de usarlo con los satelites, debemos cambiar el (o los ) filtro ceramico de 455, en estos casos tiene puesto el cfw455 "E" de 12 kcs y reemplazarlo por un cfw455 "D" de 15 kcs (en ambos casos a -6 db), dandonos un poco de tolerancia para compensar el efecto doppler del satelite (tengamos en cuenta que el equipo se corre de 5 a 5 kcs). Esta reforma la hice hace mas de un a.o y recien ahora la probe a fondo y su comportamiento es exelente...cualquier comentario o duda qrv.....Omar 73's de Omar - LU5EO @ LU5Eo.#SUR.BA.ARG.SOAM -------------------------- cut here -------------------------------- ---- Top Of The Rock BBS - Lilburn, GA SYSOP: Steve Diggs UUCP: totrbbs.atl.ga.us Snailmail: 4181 Wash Lee Ct.

I have an AEA PK-232MBX that works great. It is simple to run, a little awkward at first.It will do all modes except GTOR. The price runs around $275-300. I also have a Kam-Plus tnc that I recently purchased. It is more complicated to run than the AEA. It will do all modes including GTOR. The big difference between the Kam and AEA is that the Kam will work HF and VHF at the same time. The AEA will only work one at a time. The price for it is about $300.00. There is a lot of dx you can get on hf, and I feel you will enjoy it a lot. It is a little intimidating at first, though. I will also recommend buying the PC-Packratt II for the AEA, and the Host Master II for the Kam. Be sure to tell them it is for a Macintosh computer. Mfj also makes them, but they don't have all the frills the others do, and the price isn't that much cheaper. Good luck, and I hope to meet you on Hf sometime. 73's...Mike, KE4CLE * QMPro 1.50 42-2694 * All rising to a great place is by a winding stair. ------------------------------ Date: 29 Aug 1994 17:48:20 GMT From: newsgw.mentorg.com!wv.mentorg.com!hanko@uunet.uu.net Subject: MSYS and WP pages To: ham-digital@ucsd.edu In article <1994Aug28.172043.17651@news.csuohio.edu>, sww@csuohio.edu (Steve Wolf) writes: |> Demetre Ch.

Seems my MastrII is one of the latter types you described. I picked it up at the Dayton Hamfest this year, and from the guys here in Atlanta who use MII's for voice repeaters, this one is of the newest production designs they've seen. My exciter has numerous adjustments to it; most of them are vertical metal cans with a plastic circular protrusion out the top. My progress at this point...is that I have obtained my re-crystalled ICOM's (EC's) on my intended frequency of 441.0 MHZ. I have inserted 5C's on both the transmit and receive sides to provide compensation, if needed. I split the compensation curcuit on the control board to prevent Xmit audio from swamping the receiver. (I still get a curcuit with about 20K resistance between them though. Figure that should be enough separation) I have tried inserting 9600 audio already on the Compensation curcuit, but with only .6vdc signal level, no appreciable deviation was noted on the carrier. Getting the curcuitry to adapt amplify the .6vdc output of my MFJ built 1270+MFJ built G3RUH is my current holdup. I have yet to find anyone in the Atlanta HAM community that can lay out the curcuitry to match the G3RUH output with the 5vdc + deviation signal level required to properly deviate the MII's output. I would be happy to trade/pay/beg/whatever for anyone who could produce that curcuit design for me. Given a curcuit drawing, I can produce the whole thing, as I have the requisite assembly skills and tools. Just can't do the TTL design. On the receive side, I must be close, as I can already receive the beacon transmitted by my personal station with the GE MII hooked into same 1270+G3RUH. It would help a great deal if you could give me the component ID's on the capacitors to remove in the IF section. BTW, my MII actually has a pin labelled IF which comes all the way out to the control board in front. Does yours do that? Aforementioned friends here didn't believe it until they saw it. Finally, seems all of the Icoms for GE MII's have a filter RC curcuit in near the varactor. Did you have to remove that filter to get proper xmit ops? Also, would be happy to forward two 5C's to you in exchange for curcuit diagrams...then you could just plug them and and next winter....nnnnnooooooo problems when it gets cold. Remember, temp. compensation only kicks in OUTSIDE of 0-55 degree C temp range. I look forward to your reply.

To: ham-digital@ucsd.edu Adrie: I use a Mac SE for packet. I have the SE connected to my PK-88 with a modem cable purchased at the local computer store. the PK-88 has several cables, because I use it with different radios. You just need the cable for your radio. If you don't want to make up a cable, MFJ sells cables for connecting various TNCs to various radios. The price of each is in the $15 range. For software, no special packet program is needed. On the Mac, I use shareware obtained from my local Mac user's group. It is called ZTerm, and among other neat features, has a full scrolling buffer. You can also write to your disk as you load the buffer with incoming and outgoing text. I haven't tried an LC, but I think the fellow across the hall at work has one on his desk. Ij'll try my hookup on his machine and see how it goes.
