Opinions expressed are my own. I hope they are useful, but policies and procedures vary widely from one location and group to another.

What I describe may not work for you and may even be unsafe. Always follow your local policies and procedures!

Also, unless specifically mentioned, this site is about VHF/UHF operations and not HF, which is very often different for very good reasons.

2016 CEV Frequency Plan Posted

The first draft of the 2016 California Emergency Volunteers EMCOMM Frequency Plan for San Joaquin County (whew!) is now posted on this site.

There is only one significant change from 2015. Channel 8 and 28 are now designated STCKPD as the 147.105 repeater has been moved from the Kaiser Clinic on West Lane to Stockton PD headquarters downtown. The PL has been changed from 67.0 to 94.8.

The repeater is located with, but not linked to, Channel 11 and 31 444.325 PL 94.8.

The plan is available as a PDF and in both comma-separated-values (CSV) and Excel formats for easy importing into radio programming software. Both VHF and UHF frequencies are included.

Comments and corrections welcomed.

Are Your Batteries Charged?

Imagine this: You’re in the middle of your daily routine when suddenly the ground starts shaking… hard. You recognize it as an earthquake, but you have never felt one with this intensity. The lights go out and you realize there is a total power outage. After what seems like an eternity, the shaking subsides and you notice an eerie silence all around you as all lights, machinery and electronics are no longer operating. “How bad was it?”, you wonder. Turning on your AM/FM radio, you discover this was a major quake felt all over the region. But you’re a ham, right. All you have to do is grab your handheld radio and tune in to the local repeater. That is, if your batteries are charged. 

Even the most active of us in the hobby sometimes go long periods of time without using our talkies. If yours is powered by a lithium-ion (Li-ion) battery, you might be lucky as these batteries tend to hold a charge when not in use. Nickle-metal hydride (NiMH) batteries, however, self-discharge over time; a real problem if you don’t stay on top of them. What to do? 

The most obvious solution is making a routine of charging your batteries. Another is to purchase an alkaline battery pack (AA or AAA size) for your handheld. Some alkaline batteries now claim a shelf-life of 10 years, providing a high degree of dependability, although it’s still a good idea to periodically check your go-kit for missing or expired items. Note that some cheaper brands of alkaline batteries can leak with age, damaging your equipment. Search for Dave N5FDL’s earlier (April 21, 2013) blog titled, “Switching to Duracell” for more information.

Another way of insuring your batteries are charged and your radio is functioning: get on-the-air and check-in to your club’s weekly net. Most all ham radio clubs have a net, and no better way to insure all is working properly with your radio than to use it regularly.


Scanner Frequencies for San Joaquin County

I have been asked to update and post a scanner frequency list for San Joaquin County. These are frequencies — many now P25 digital — that I care about. This list has been updated but still needs work so please tell me about changes and additions that I should make. I have also added the current CEVOL ham plan. Both are in printable PDF format.

What's Wrong With Tornado Chasers

Am I the only one bothered by videos showing a violent tornado devastating a small town, killing one and injuring 19, while the tornado chasers sit idly by amazed by their good fortune?
