Re: [Repeater-Builder] Info on IFR1500
Hi Some of the 1500's had a GPIB bus connector on the back which looks like a parallel port-DB25. If you have that model, then all you need is a GPIB controller and some (major) programming and voila, you can have the output from your IFR. If yours doesn't have the GPIB then there is no provisions for any kind of output. Russ AE6UX Jed Barton [EMAIL PROTECTED] wrote: Hey guys, Any way of hooking up the IFR1500 to a computer to email data from certain tests? In other words, can I hook it up to a computer so it can import the data to be emailed for someone to take a look at? Thanks, Jed

That's not a bad idea. I'd probably want to set it at 120 seconds; one of the repeaters I grew up using had a 4-minute timer. I program most of my radios for 300 seconds or five minutes, just in case of stuck keys. What is done on ham gear is one thing, but on commercial fleets, it should never be more then 90 seconds, and for public safety should be no more then 60, preferably 30-45 seconds. While I was driving to work yesterday, and had my local fire dept repeater in scan, a dead carrier suddenly appeared. In listening, it was obvious that someone was sitting on their mic button. You could faintly hear talking, and mobile flutter. It continued for, oh, maybe 20 minutes or so. Either they never programmed the TOT on the radio, or, knowing FD's, they have an old radio that doesn't have one, like an HT-90 or something, maybe even an MT-500 or HT-220... MAJOR issue... -- Jim Barbour WD8CHL
Re: [Repeater-Builder] Another TKR-820 Question
Well, I figured it out. I guess there's at least one guru ;-) who knows how the line-out works. Me. Man, I hate surface mount technology, especially when your only copy of the service manual is a fuzzy pdf from a scan ! Thanks to Dave's (K7IOU) younger eyes. FYI-IYGAS:I'ts good sounding audio, much better than discriminator audio which has been de-emphasized with a capacitor in the feedback of an audio amp in the controller. Kenwood says it's 600 ohms, -10dBm, -6dB/octave, 300 - 3000, however it appeared very sharp and still required a 0.0047 uf in the audio feedback. Since it used switched line-out, it caused a nice little chirp when the repeater input squelched. Discovering how to eliminate the CO switching was the secret. Plus, DTMF detection works great with this audio so it will remain in the configuration. If it's good to go by the critics, we'll put it on the mountain soon. de WD7F John in Tucson - Original Message - From: WD7F - John in Tucson [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, March 06, 2007 6:04 PM Subject: [Repeater-Builder] Another TKR-820 Question The line-out de-emphasized audio on pin 10 of the accessory jack of the TKR-820 is switched by COR. Discriminator audio is continuous. Does any Kenwood guru know what signal is responsible for switching off the audio when COR is not active? It appears that the microprocessor on the Display Panel could via Q6 and R45, but it doesn't appear to be the case in real life. Anybody know.

Re: [Repeater-Builder] A Monday Laugh
Off subject, but do you remember a time back in the '70s that this repeater was shut down due to a duct to Hawaii that let an 82 repeater in Hawaii come booming through in LA. I had a Wilson handi-talkie with a 1/4 wave ant taped to the roof of my rent car in LA and worked a guy walking on the beach in San Diego using a talkie through the Hawaii repeater. Still my longest distance DX on 2 meters. 73 - Jim -Original Message- From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wed, 7 Mar 2007 9:55 PM Subject: Re: [Repeater-Builder] A Monday Laugh The 146.82 repeater in Los Angeles has been on a 30 second timer since the late 1960s. 30 seconds is longer than you think - you can get a lot of info across in that much time if you think before you start talking.

If you are giving a traffic report and it takes over 30 seconds, you are not giving a report. You are having a conversation. Keep It Short and Simple.

My opinion is that a repeater should be used a lot, that way it's known to be reliable in case of emergency use. Plus, as you say, there'll be people listening.

RE: [Repeater-Builder]Timeout Timers (Was: A Monday Laugh)
Richard, Please re-read my post. It is the USER radios that have a 30-second time limit. The repeaters have three minutes, although they are commercial units that can operate continuously. A user timeout will inform a long-winded talker that his time has expired, with a tone from his speaker, while a repeater timeout will never be noticed except by others. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Richard Sent: Thursday, March 08, 2007 12:49 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] A Monday Laugh 30 seconds is way too short.
