Good Evening fellow Hams and Railfans,
Today I would like to introduce to you the lovely world of operating trackside mobile. What is trackside mobile you ask? Operating trackside mobile is operating your radio from trackside while rail-fanning. Now this can be done in a variety of ways and in this blog I would like to show you Some of the basics.
Operating trackside has it's benefits, you can have someone to talk to, test equipment and meet like minded hams who share the same passion for trains as you. I got my start in operating trackside mobile when I got my tech license. Most mornings I would tune into the Barometer Net and check in when there were no trains around and for a good reason and that reason is also one of the major drawbacks operating trackside.
That reason is the fact you can cause unintentional harmful interference and knock out communications on poorly maintained receivers. (The Railroad always maintains their equipment right?) Take for example the railroad operates in the 160-161 Mhz Band and the 2 meter band is 144-148 Mhz just 26 Mhz apart. Frequency wise this may seem like a good enough separation however there have been reports of train crews that have complained about amateur club repeaters that has interfered with the train crews radio. Some sites like Bellevue Ohio have only a 440 Mhz repeater and this is a much better choice than cranking 50 or 100 watts of 2 meter power near a major rail hub. If you can operating on 440 Mhz and HF are the best options but, if you don't have that option or you want to operate on the 2 meter band here are some tips.
The first thing thing is to monitor radio traffic traffic and listen for trains in the nearby area as a railfan most of us do this anyhow. The reason is you don't want to knock out the radios with possible work like this in the picture below being done. Besides causing harmful interference and creating a nuisance you could possibly get someone killed. If the train crew can't communicate or hear an important track or train information then there could be serious consequences and YOU!!!! would be responsible.
