To: ham-digital@ucsd.edu This is a non-ham application but I'm sure this is the correct place to ask. I need to set up a temporary HF digital link where one station will be uploading and downloading ASCII (and maybe binary) files from the remote. The remote may not be manned continuously. The equipment will be Kenwood HF Transceivers with PK-232s. I can use the 232's software at the manned station, what software do I need at the unmanned station? Something like a barebones BBS would be the ticket. Your quick response is appreciated.

Note in the signature block that my Packet Radio has changed. >>> ALTERNATE BATTERY SOURCE In April Jim forwarded me results of his efforts to modify 9.6 volt Makita power tool batteries. Cut directly from his Internet message, here are his observations (thanks Jim!): "Just the other day I did something I've been dreading for 6 months. I removed the stock battery from my Zenith ZL-2 Minis- port and connected a variable voltage power supply directly to the computer's power terminals. After adjusting the supply to six volts, I powered up the computer and verified that it was working properly. Then, taking a deep breath, I slowly cranked the power up to ten volts. No explosions, no complaints from the Minisport power supplies, It took it just fine. Great, now I can use my 9.6 volt Makita batteries with the laptop as part of my portable packet station. "Since the internal Zenith supplies are all switchers, current drain is inversely proportional to battery voltage. This means no power is wasted regardless of whether the voltage is 6.0 (stock Minisport battery) or 9.6 volts (as in my Makita pack). I measure 450 - 650 Ma drain with a 6.0 volt source (depending on backlight brightness), but with a 9.6 volt source, only 340 - 425 Ma is needed. The Makita batteries are about 1400 MAh ca- pacity and run my ZL-2 for 3 hours with the backlight on full. Obviously, a 7.2 volt external would work also, with proportion- ally reduced operating time. "I had to make a better way to get the external power to the ma- chine than the alligator clips I was using. I thought I'd share what I built with you all. Here's how to make a fake battery pack for your Minisport. "Begin by cutting a 2 1/4" by 5 1/8" piece of single sided glass epoxy Printed Circuit board material. Remove 1/16" strips of copper along five lines as shown in the following diagram. |<-------- 2 1/4" ---------->| >|---- 1 1/2" --->| | >|- 1 1/16" -|< | | >|- 3/4" |< | | | 5/16" | | | | >| |< | | | | _______ _____________________________ ^ | | o | | o | | < drill holes for | | | + | | - | | power wires | | | | | | | |--|----|---|----|-----------| < remove copper | | | | | | for 1/16" | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5 1/8" | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __v___ |__|____|___|____|___________| ^ ^ ^ ^ Remove copper along these four lines "Drill the two holes close to the edge so solder will not inter- fere with the power contacts on the machine. Only the two small rectangular areas with holes will actually be energized. Isolating these minimizes the possibility of short circuiting the battery. Nevertheless, you should always disconnect the external battery when the fake unit is removed from the computer. "You can remove strips of copper by double scoring the material 1/16" apart along the indicated lines, then gouging out the met- al with a knife or wood chisel. With some patience, you can also do it with a hacksaw or a hand grinder. My favorite method is using a 1/8" drill bit in a small drill press as a router. I raise the table until the PC board is just touching the drill bit. Then one or two thickness of 3 x 5 card under the board raises the copper just enough so I can route out metal along the lines by moving the board under the bit while it's turning at the highest speed. I have a piece of wood with a vertical fence screwed to one edge that I can "C" clamp to the drill table to help guide the PC board while routing. "You will need to solder a power cable directly to the board, or glue some sort of jack on the board to accept a power cable through the battery cover hole. The NEGATIVE terminal is nearest the front of the Laptop. The POSITIVE terminal is the rearmost. You won't need a connection to the center terminal, it is used by the Minisport charging circuit. Use a minimum amount of solder and file the solder bumps down smooth. "Complete the fake battery by gluing a block of wood about 1 inch high to the glass side of the PC board. This takes up the slack in the battery compartment so the board is pressed firmly onto the computer's power terminals. You will have to sand the block to just the right height, or glue on strips of cardboard for ex- tra height if it's too short. "One problem with using a higher than six volt battery with the Minisport is that the low battery voltage alarm doesn't work. It appears that by the time the 9.6 volt pack is discharged far enough to trip the alarm, it's going down so fast that there isn't time for an indication. Save your work often if you're near drop out time. It should be possible to construct a sepa- rate discharge alarm on the fake battery board that will trip at a higher voltage and give a couple of minutes warning. "I have also created a real battery pack for my Minisport by us- ing one of these routed out PC boards, and hot gluing five "C" size nicads to the top. It works as well as the 1700 MAh Minis- port batteries but I have not figured out a way to use the Minis- port charger. Also the exposed battery power terminals on the bottom require care to avoid short circuits. >>> DRIVE EXPANSION PINOUT On the back of the Minisport is a small plug with a rectangular external form and an internal "D" shape. I have been unable to identify a source for this connector, but several people have asked for the pinout. Here it is, compliments of wa8wzx. The top row of pins 1 through 19 are all sequential odd numbers. The bottom row has pins 2 through 20. Pins 4, 10, 12, 19 & 20 are all ground.
