What OS versions on each.
I have a feeling the "other" mac has a newer version of the OS with more strict access right policies and default behaviors.
Check the write time-stamp of the xml file on the G5 before and after saving to confirm that it is indeed saving.
73,
Chris VA3CDG
The other Macs have Snow Leopard 10.6. That I did not consider and could very well be the reason for the behavior. This iMac is running 10.4.11. I will have to install Leopard into this machine and see it that is the cure.
Thanks for your reply and remarks. |

We just installed FLDIGI into a iMAC G5 and did the complete configuration... just like it is on another iMac we have here. The problem I am encountering is that when I go to save the Configuration Files, I do not see the normal file save panel with the options for selecting where one wishes to save the file. I took a look at the files area for FLDIGI and see the file ( fldigi_def.xml ) which according to the FLDIGI Help Site... is the correct name of the configuration file. We do not know why the prompts are not showing after the save command and the files are not being saved. When we re-boot the Computer and open FLDIGI, its the default settings and not my changes.
What am I missing Here?

When dealing with somewhat technical items in the PSK31 hardware arena... Caveat Emptor. The Gigaparts salesperson I spoke to on the phone did not know his product... and recommended a particular cable between the SignaLink and my FT-847. Things just did not sound correct so...I checked with Tigertronics and they informed me that it was the wrong cable. I have purchased from Gigaparts a number of times and have always been vert satisfied but, sometimes sales people do not have the technical skills to sell some pieces of equipment, its always best to check with the Manufacture if your in doubt.

Is it fair to say that the ARRL Propagation Reports provide adequate information for the Amateur Radio Operator and SWL enthusiast? With so many competing sites on the Web offering Space WX... one wonders if using just one source like the ARRL is adequate. And, maybe there is even a Propagation Prediction Application that utilizes daily info to present to the user via the Computer. Recommendations and Information Welcome. ??

Charles:
I have read page 16 most of the topic is regarding TNC and RTTY AFSK operations, it does mention "and other digital modes utilizing USB or LSB. So one could accept that a phase shift signal could be utilized in the USB or LSB mode but Yaesu did not elaborate here. The PTT is not the typical Pull-Down PTT and requires some current. Also, I will have to use the PTT on the DATA in DATA out port so the Microphone audio will be disconnected from the normal MIC input, using the standard PTT connection on the rear of the radio does not disable the front MIC audio, this was probably incorporated so one could use a foot switch with a mic/headset system. I will have to make a small circuit for interface and for keying the PTT line. The 847 was built before PSK31 was popular so Yaesu did not incorporate the necessary Gazintas and Gazoutas on the back of the rig. . Back to the drawing board and on to the building bench again. Yaesu's newer xcvrs all have provisions for Digital Modes, the 857 is a good example of that.
Thanks for your reply and remarks.

We are considering interfacing our FT-847 to our (SignaLink USB). Boy... Yaesu did not give much consideration to Digital Modes while running the 847 in the SSB mode nor did they make any provisions for PTT keying during that type of application. Oh Yes! I can use the front MIC connector but I prefer to make these connections on the rear leaving the MIC connector for its intended purpose. I see that DATA IN/DATA OUT can be used for this purpose but the PTT must take a powered key circuit, I prefer to make use of available sources but do have a problem making to apply a + voltage for keying the PTT circuit if necessary. Is it possible to use the any pins from the CAT connector to provide PTT keying with a pulldown to GND or such? I cannot find much info on the CAT connector with my User and Maintenance Manuals for the 847.

Philip: Thank you for your reply and the information. I have noticed in my readings that many PSKERS using applications other than FLDIGI report their success in configuring their applications to report to the PSKREPORTER Site. I have browsed around in my FLDIGI application but without some instruction... I am not about to make many changes now that is is working fine. HIHI. TNX AGN, Don W6PJJ |

I have been fooling with the PSK-Reporter on their Site and with the Link to my Application FLDIGI. Looking at the Site information on the PSK-Reporte Site I'm not sure how the PSK31 receiving stations are reporting to the PSK-Reporter on the Internet obviously they allow their application to interface the WWW through their provider but the particulars elude me at this time. Is the reporting of the receiving station due to a particular application they are using for PSK31?

W6PJJ,
Did you ever get this working? The SignaLink USB is probably the simplest interface around for getting on the air quickly.
In Fldigi, you simply need to choose USB Audio Codec for both your input and output sources. That's it.
Interesting that you had some luck with the PL2303 for PTT. For the most part, the Prolific chips are some of the more troublesome chipsets for OS X (poor drivers), whereas the FTDI and Keyspan are much better supported in OS X (especially the Keyspan USA-19HS). Of course, you won't need that for PTT any longer with the SignaLink.
Ever since you got your Mac, you've had troubles with the USB...lots of time spent looking for documentation on what is a standard USB port; something I can't figure out, but I hope you got it working. If not, feel free to shoot me an email at k3dcw at arrl.net.
Dave:
We had very good success with the PL2303 and have used it in several HB projects keying transmitters through some opto-coupling. I also picked up a FTDI as well and have plans for it in the future. I have interfaced the Mac quite successfully, USB is USB some of the problems others have faced seem to be in the Applications control of the USB bus, timing etc. Thanks for your comments.

Didn't mean to imply that the skat is unimportant, meant to try to tell you how I have to handle the customer pieces where that voltage point information is unabailable, sometimes the schematics can't be found, either, but we like to give it the old college try anyway, and more times than not can come up with the repair, along with the happy customer that will not only return, but likely give us that invaluable referral and reputation via the customer's bragging rights.
From your report, I'd be thinking that JFET not switching is telling me something important...
There is likely only one thing, possibly just one component stopping the show. Don't get all flustered by the "safeguards, over current, over voltage, triggers and resets" stuff unless and until you eliminate the simple things. Rectifiers. Unregulated supply feeding all the rest, sometimes a disconnect is in order to see what that is doing. Filtering. Excess ripple can cause all sorts of problems with the rest of the circuits. 'Scope is handy, but not a necessity there. The common DMM set to AC and used on DC rails can tell you a lot about the filtering/ripple situation. So can simply shutting it off and connecting a known good electrolytic of proper or better voltage rating right across the connects of an existing one. If tacking in the extra cap with a couple of insulated jumper leads makes things happen, well, you've found a bad cap.
When something simple like that JFET switch is inoperative, I consider that clue to be a "gimmie" -- don't convince yourself that it is something complicated yet. JFETs often don't switch in the presence of ripple.
And, yes, I've owned and operated TenTecs over the years, because I'm first and foremost a CW freak. TenTec QSK being the thing of beauty. But they liked that power amp design that, while being super clean, needs to have a power supply that can cut off in the presence of high SWR before an RF transistor can give it up instead. But I must say that TenTecs protection circuits are very good, incorporating rather conservative design and haven't YET had to delve into the protection circuits in them, other than Ye Olde Fast Circuit Breaker types found in the C supplies from days gone by. The electromechanical breaker would sometimes fail. But then I've yet to own a brand new TenTec out of several.
You can find it.

I'm certain I can... we have been working on the ham gear for many years, but about 15 years ago we sold off most of the test equipment and the scope would really come in handy in looking at the DC. When we get the garage warmed up we are going to cure that problem but with hands shaking and a fair mood of disgust due to the cold we have to tackle this down the road or work on it in the Dining Room. HI HI. 73's and TNX for your advice and support Clark. |

Thanks for your reply and the information. This is not just a basic 12VDC power supply it incorporates several levels of safeguards, over current, over voltage, triggers and resets... and I can assure you, if the schematic was not important the Manufacture probably would not have provided one with the user manual. I did some basic measuring last night... we did discover several areas of concern, no Bias on the Pass Transistors which is controlled by a chip regulator and a control transistor and the JFET that supplies power to the PWR on LED is not switching, pointing to the Regulator Board. But my garage was very cold and I gave up quickly, hi hi. I appreciate you taking the time to explain the process and procedures you use, when we get the garage warmed up we will dive into this project again. TNX

My Ten-Tec Paragon Power Supply Model 961 gave up the ghost, so I decided to repair it but, when I broke out the manual for the power supply I was a bit disappointed, there were no reference voltage check points or any mention of voltages at particular junctions of components on the boards.
I am looking for a reference voltage test chart for this supply, if you know where I can find one, it would be most appreciated. I contacted Ten-Tec they do not supply a reference voltage check list.

Greetings:
I have been running this iMac with a Home-Brew interface for months but have been experiencing some problems with the multi layer audio board I choose to use as part of the interface, we used a PL2303 Serial to USB chip and some isolation for the PTT action it has worked flawlessly, I wish I could say so for the Audio Board. So, we decided to try the SignaLink. The documentation for operation with a Mac is nonexistent so to speak. And, I was concerned with how the SignaLink was to work in the Mac USB world. I finally found a combination that allowed the RX & TX to work. As for any on the air tests I have not been able to yet. The Band was closing down when I arrived home this evening. If you can shoot your configuration I would like to compare it to what I have setup on FLDIGI.
I will send you an Email on as you requested. I appreciate your reply and offer for assistance Thank You.
Regards,
Don
