Just a couple of photos taken while reinstalling a Quintron 72 MHz paging system simulcast transmitter for a client. This is the “main” simulcast transmitter. We switched over to the “backup” transmitter to give it another workout while pulled and I did a re-check of this transmitter, which I had repaired and realigned back around […]
Doing the engineering work on a multi-site, simulcast paging system necessitates keeping a check on the operational status of several transmitters which are — by design — geographically spread out all over the place. Anything which can automate some of the process of testing (and, ideally, provide remote, real-time monitoring) is a huge help. Not […]
Well, it’s been a quiet week in Lake Wobegon… wait, we aren’t in Lake Wobegon, are we? Nope. And there is quite a lot going on around here lately. The tower replacement in Auburn is progressing nicely: they’re stackin’ it high so the signals can fly. While those guys are going up… up… up… I’ve […]
This video is a demonstration showing the RF Power and VSWR Monitor & Alarm System I recently designed and built. The front panel and chassis used to be a Glenayre Power Monitor panel, but after being completely gutted, retrofitted, painted, etc., it is now a custom Arduino-based build. I finished creating and putting the front […]
These two short videos show the testing of the v2_3 code running on the Arduino-based power and SWR monitoring system I’m developing and building for a client’s Quintron and Glenayre paging systems (but the system can be added to virtually ANY RF transmitter — it’s just a matter of having the correct bidirectional RF power […]
Much to the surprise of many, the paging industry is alive, well, and still quite popular. To wit, I finished building, wiring, and aligning this Quintron system over the course of the past few days, which will be installed in the place of an existing system. The existing system is working, but it has been […]
