1. [TRLog] The changing radius of Earth (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Fri, 10 Dec 1999 03:08:52 -0800; Mark, I understand that there are still some flat-earthers out there. Tree has set up the program so they can set the earth radius to infinity by typing in RADIUS OF EARTH = 1/0. When operating in th; /archives//html/TRLog/1999-12/msg00108.html (8,601 bytes)
2. [TRLog] Footswitches (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Mon, 13 Dec 1999 20:53:23 -0800; If you can't find them surplus, McMaster Carr Supply Co has a whole series of industrial footswitches in their catalog. Mike, W4EF.......... Dictation equipment uses foot switches and are often avail; /archives//html/TRLog/1999-12/msg00141.html (9,348 bytes)
3. [TRLog] Multiplier Needed Window (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Thu, 12 Aug 1999 08:12:14 -0700; I also saw this kind of behavior this past weekend (v6.30). I had an additional problem in that the multiplier needed information would only stay on the screen for a second. It appeared between the t; /archives//html/TRLog/1999-08/msg00042.html (9,251 bytes)
4. [TRLog] CW Keying Circuit Question (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Sun, 6 Jun 1999 16:54:33 -0700; Jack, Check the T-4XC manual to be sure, but I think the Drake uses grid block keying (negative voltage). You will most likely need a PNP transistor or a FET to key it properly. Mike, W4EF...........; /archives//html/TRLog/1999-06/msg00032.html (8,385 bytes)
5. [TRLog] RE: [TenTec] Paragon and TRlog (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Mon, 18 Jan 1999 14:30:10 -0000; Rich, As far as I know, the Paragon 1 uses a different protocol than the Omni which if I am not mistaken is similar to the Icom protocol. Unless someone has come up with an emulator, I don't think Tr; /archives//html/TRLog/1999-01/msg00104.html (7,487 bytes)
6. [TRLog] Need help with Keying/PTT/Paddle interface (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Mon, 25 Jan 1999 15:25:15 -0000; Has anyone tried a darlington pair (beta multiplier) in place of the keying transistor? This should draw very little current from the interface. Mike, W4EF Boy you got that right! My opto box would k; /archives//html/TRLog/1999-01/msg00135.html (9,911 bytes)
7. [TRLog] Need help with Keying/PTT/Paddle interface (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Mon, 25 Jan 1999 16:37:01 -0000; Good point - the darlington adds one diode drop to the Vce saturation voltage! Exactly how low do the modern transceivers need to go anyway? One would think that pulling them down to 1 volt would do; /archives//html/TRLog/1999-01/msg00136.html (9,216 bytes)
8. [TRLog] Need help with Keying/PTT/Paddle interface (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Wed, 27 Jan 1999 04:04:41 -0000; Hi Nick, Actually, the darlington does add a diode drop to the Vce of the output trasistor, since the Vce of the output transistor is in parallel with the sum of its own Vbe drop and the input transi; /archives//html/TRLog/1999-01/msg00145.html (9,679 bytes)
9. [TRLog] Re: little problem (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Fri, 25 Dec 1998 16:50:59 -0000; I installed a small push button switch for the PC speaker on one of those blank panels that are made for covering unpopulated card slots openings on PC backplanes. This allows me to turn off the PC s; /archives//html/TRLog/1998-12/msg00151.html (7,787 bytes)
10. [TRLog] Paddle Input Problems (score: 1): Author: W4EF@pacbell.net (Michael Tope); Date: Fri, 6 Nov 1998 15:39:13 -0000; Jim, Make sure Pin 14 of your parallel port has +5Volts on it (this is the common terminal for the two pullups. If you are using the Relay Control Port feature to switch radios, pin 14 will toggle be; /archives//html/TRLog/1998-11/msg00058.html (7,738 bytes)

The multiport feature is configured to use the com1 ports of the two computers and appears to be working fine. I also have; /archives//html/TRLog/1998-09/msg00086.html (6,789 bytes)
