Hi all,
I have got a PowerMac 3400 (currently running under System 7.6.1) lying somewhere and I would like to connect it to K2 for logging, using it in digital modes, etc. However, I have got two problems: 1. I could not find the cabling diagram. 2. I have got difficulty in figuring out which software to use. Most of what I could find runs under MacOs X. Any suggestions? 73!

You may find some earlier version of MultiMode (Black Cat Software) will work.
Good luck and 73, Paul _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

Bekir :
One additional option may be to put Yellow Dog Linux on your Powerbook 3400. Having Linux on the machine may open up some additional options to you. If you have enough disk space you can set it up for dual-boot (Mac OS / YDL ). See ... http://www.terrasoftsolutions.com/support/hardware/others.shtml It looks like older versions of the OS up to V3.0 support the hardware and it is likely the newest version still does as well. I have YDL V3 running on a old Performa 6360 and it runs pretty well. It is likely that you can find a cheap copy of YDL V2 or V3 on Ebay for about $10US. Best of luck, Michael VE3WMB P.S. Both TLF and xlog (linux logging programs) support the use of hamlib which would allow interfacing to the K2. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Michael,
[snip] >I have YDL V3 running on a old Performa 6360 and it runs pretty well. Thanks for the interesting idea. However, I am a (old type) Mac only person and I try to stay that way as much as I can. Over the years I ***had to*** learn a few things about WinTels (even then only a FEW things). So, anything new, including MacOs X, I try to evade as much as possible. I feel like sticking to Paul's idea and give MultiMod (by Black Cat Systems) a try. >P.S. Both TLF and xlog (linux logging programs) support the use of >hamlib which would allow interfacing to the K2. Do you happen to have the cable pin-out diagram for connecting an old Mac to a K2? 73!

No I don't, but probably the easiest way to do this would be to to find a Mac specific Modem Cable (Ebay for $4 US). It will have the correct DIN connector for the Classic Mac serial port and a DB-25 connector at the other end. My guess is that you would just need a DB-25 to DB-9 adaptor to connect the cable up to the K2 (it looks like the KIO2 has a DB-9 on it). The adaptor, I believe, should be straight through as I am assuming that the computer would view the K2 as being DCE, just like a modem.

Yes, and then you get to buy a bunch of parts for your KIO2<g>!
DO NOT CONNECT RS-232 to your KIO2 without opening all unused (by RS-232) pins. ONly Sig Ground, TX and RX go from computer to K2. All other lines on the KIO2 are not RS-232 and can't tolerate the +- 15V the computer will supply.

I am one of those old generation (!) people who do not move a finger without reading the manual first. >;-) Now, as for reading manuals, I have got an interesting case for all of you to comment on. Multimode's Documentation starts by saying the following for transmitting (receiving is via the sound output of the rig): "If you also want to transmit, you'll need to connect the audio output (speaker) jack of your Mac to your radio's microphone input jack. You may need to reduce the audio amplitude using a potentiometer, or attenuating audio cable. Many have sucessfully usd the RigBlaster, made by West Mountain Radio (http://www.westmountainradio.com/)." Then goes onto describe the procedure for PTT and CW: "For transmitting, you may want to be able to control your radio's PTT (Push To Talk) line. A PTT output is generated from the DTR output of the Mac's serial port. A CW key output is generated from the Transmit Data output." The diagram in the Documentation depicts a little circuit on the line from Mac's serial port to the CW Key control (and a smilar one to the PTT) such that: Mac Serial Port --> Diode (1N4148, etc.) --> 2.2k Resistor --> Transistor (2N2222, etc.) -->PTT The other leg of the Transistor goes to ground. On a diversion from this line, there is a diode (1N4001, etc) which then connects to the first leg of the transistor going to the PTT. [I hope I haven't described it too badly. The diagram is on p4. of MultiModeDocs.pdf. I tried to attach it to this message but the list does not accept attachments.] The documentation describes the way the circuit works as follows: "When the serial port output goes positive, it biases the transistor, so the collector can sink current. The 1N4148 diode protects the transistor when the serial port output is negative. The 1N4001 protects the transistor against flyback from a relay that might be lurking in the radio. A faster diode would probably offer additional protection. The connection on the Mac end would go to the DTR output line. If you'd like to use a similar circuit for CW key control, then it would go to the TxD+ line (or TxD- if you need to invert the logic of the output)." There is no problem as far as this description is concerned. All sounds logical. Looking at things from the K2 side, p. 95 of the manual says that I should have two diodes (one on each line from the dot and dash connections) on the cables going to the computer, when I connect it in parallel to a paddle. And it describes the reason as: "When you connect the keying device in this way, you can continue to use the paddle as usual. But if the external keying device is keyed, both the DOT and DASH lines will be pulled low simultaneously, via the diodes. The K2 firmware interprets this as direct external keying rather than as DOT and DASH triggers." This sounds quite logical, too. However, when you bring the two descriptions together on a single circuit an interesting case occurs. Now, I am not exactly a techie type person and learnt electronics just enough to pass the exam BUT AFAIK having diodes on both ends (i.e. on the computer side as well as the K2 side), each protecting their own respective device, there will not be any current flowing. Am I wrong? Or should I put the circuit together and test it anyway? Thanks for your help in advance. 73!

The diodes are doing two different things. Wire them up! It works great
here. In this case, you are using the computer RS-232 to key the rig, so you'll definitely be building a custom cable - TxD and RxD to the K2, DTR to your keying circuit (btw, this can fit into the DB9 shell), and NC all the K2 specific lines. The two diodes on the K2 end are to allow ADET operation (a keyer and a straightkey/computer simultaneously connected). If the DTR line pulls the pair of diodes low, both DIT and DAH go low together and the K2 assumes a straight key. If they go low at different times, the K2 assumes iambic keying and acts appropriately. So ops (up at twice the speed I can run) can fool ADET and need to turn it off. They don't need the diodes but must switch from paddles to SK/Computer with the menu. Other ops only ever do it one way or the other - and switch off ADET too. hth, Dan / WG4S / K2 #2456 -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Bekir Kemal Ataman Sent: Tuesday, November 22, 2005 1:04 PM To: [hidden email] Subject: RE: [Elecraft] K2 with MacOS Classic >Yes, and then you get to buy a bunch of parts for your KIO2<g>! > >DO NOT CONNECT RS-232 to your KIO2 without opening all unused (by RS-232) >pins.

Alternatively, some control programs tell the K2 to send the code, but sending "KEY THIS" commands over the RS-232. I'm not sure what you can do if you don't have RS-232 available. However, even old macs had USB, so you may not be toast quite yet. However, I know nothing about USB/rs232 adapters/software.

RS-232 is a protocol.
DB-9 is a connector (so is your mini-DIN). RS-232 via an RJ45 is still RS-232 (as it would be over 4 pair of field-telephone wire). Sounds like you are good to go!

As a Mac fan myself, I have lots of information to help. In fact,
both Wayne and I here at Elecraft are primarily Mac users (but we use Windows and other systems as well). Connecting a Mac to the K2 is very easy, involving only three wires of the Mini-Din 8 bundle. The Mini-Din 8 appeared on all Macs from the Mac Plus until Async serial was dropped in favor of USB around the year 2000. The connectors are still used in several USB-Serial adapters, most notably the Keyspan dual-serial devices. I usually fabricate a serial cable by taking an existing Mini Din-8 to Mini Din-8 cable and cutting it in half, then installing a male DE-9 with hood onto the cut end of the cable. You will need to make the following connections: Mini Din-8 DE9M (most folks call it a DB9M) 5 2 3 3 4 5 Identifying the Mini Din-8 pins can be difficult. The pins you need are in the middle row. The gap between pins 4 and 5 is noticeably larger than that between pins 3 and 4. You don't need to connect any other leads from the Mini Din-8 - in fact doing so could cause problems in the K2. As for Mac software and information, there is a wealth of info at the Mac Ham radio web site: http://www.machamradio.com/ Most users have upgraded to MacOS X systems, but there are still quite a few folks still using older systems. Much f the older software still works just fine, and is there just for the asking or downloading! Good luck - if you need anything else, just ask.

In reply to this post by Bekir Kemal Ataman
I tried a USB to RS232 adapter made by Belkin a couple of months ago. Sorry, I don't have the model # handy. It seemed to work okay for both rig control (using the specified cable for the K2) as well as for CW keying (using the keying adapter I had previously built into a DB9 connector shell). I was quite surprised this was the case as I expected at least one of the combinations to not work correctly. My IBM laptop only has one RS232 port and one USB port on the back panel as well as another pair of USB2.0 ports that were added with a PCMCIA card. I did very little testing with both of these modes/configurations, though, so I'm not sure if more extensive testing would have shown other problems. I think the hardest thing about the rig control was to get the "virtual RS232" set up with a COM Port ID# in the range that the rig control program would accept, I think COM1 - COM4. COM1 was already in use with the RS232 port on the back of the laptop and it defaulted to COM5 for the "virtual" port with the USB-RS232 adapter. Once I had it redefined as either COM2 or COM4 I think it then worked okay. I do know that not all USB to RS232 adapters are created equal, so I wouldn't be anxious to buy and off brand to save a few dollars. Even with the Belkin product I was a bit nervous because the case was one of those plastic cases that you can see through (Wow, look at the electronic parts inside of this Dongle!), so I was worried about it being susceptible to my Tx or likewis if it would be spewing noise that my Rx wouldn't like. As it was just running QRP and later 100W I didn't see any problems from the Tx side and didn't really notice any on the Rx side. Again, I didn't do extensive testing though, and higher power may be a problem, or as they say "Individual Results May Vary". I bought mine at Staples where there was a 100% return policy if not 100% satisfied.

There is another mailing list that Mac users should subscribe to.
This is the Ham Mac list. For more info, or to subscribe, go to: http://mailman.qth.net/mailman/listinfo/ham-mac You will find all sorts of great folks there, including the authors of Mac ham software such as MultiMode and MacLogger DX.

Great info Jack. Thanks for all the input.
I normally use a G3/300 for my daily work. My old Macs (7200 and 7400) serve as my mail and web servers. I have also got a PB3400 lying around. The story is this: I got involved with Ham Radio after the terrible earthquake we experienced in 1999, as a result of my search and rescue activities. Having grown (!) to 100 kilos since than, I had to direct my interest to something technical (like disaster communications), since I cannot go into collapsed buildings with such a large body. Seeing a KX-1 made by TA2AH, I thought I found my dream rig, the ultimate disaster communications transceiver, since all you need is a few batteries and a piece of wire to communicate with the rest of the world. I took the exam and upgraded my licence, for the love of the KX-1. However, as things turned out, I could not proceed with CW after a certain point, because I could not stop translating everything into the dots and dashes in my mind, no matter how hard I tried. So, I decided to give it a break for sometime. Just then, TA2AH sold me his K2, to build himself a K1. Naturally, K2 won over KX-1, since it has got other abilities on top of CW. So, I started investigating about other ways of communication, namely the digital. Because every mode has got different advantages in case of a disaster (for example you cannot read a long list of needed suplies one by one on voice, you need some form of digital communication). Having a surplus PB3400 around, it became the natural choice for this purpose. Thus the search for the pinouts. I'll let you know how I proceed. >There is another mailing list that Mac users should subscribe to. >This is the Ham Mac list.

Just a tid-bit of information here (useless though it may be) - the RS232
standard does specify a connector - and in fact it is the DB-25 connector. Other connector configurations may carry the RS-232 signal levels and signalling protocol, and can come in many different flavors. The one we seem to be most concerned with is the DB-9 (more properly a DE-9) connector which has become the de-facto 'standard' on IBM compatible PCs. The Apple world has used mini-din connectors for most everything (including RS-232 level signals) for a long time. 73, Don W3FPR > -----Original Message----- > > > Actually RS-232 refers to the signal names and levels, although a > DE-9 (Cannon nomenclature) connector is often used (sometimes it is a > DB-25, particularly for modems). > > A good place to find information related to Macintosh radio > applications is the "ham-mac" mailing list <http://mailman.qth.net/ > mailman/listinfo/ham-mac>. > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
