Tampa Bay DMR Repeater Now Online for Testing

As of July 1 there is a new wide area DMR repeater online testing on 443.425 MHz +5 please note this is a temporary frequency and could change at anytime. The repeater is located at 400ft in downtown Tampa. I will update the repeater page here and also over on the FLSCG.org should the freq change. Please programing it into your radios and give me a shout over on the WCF Local 2 talk group.

MOTOTRBO Out of Band

Please Note: This is a software CPS codeplug mod. Once this mod is performed, you must use the backup file created for any future editing out of band. any attempt to read the radio via the CPS will automatically restore default values instead of  “incorrect”, out of band frequency entries, and the process will have to be repeated again.

1. Download and install HxD, an excellent free HEX editor: Download Link
2. Launch MOTOTRBO CPS, and read the radio and save the file. Note the band limits (in my example (450.000 – 512.000 MHz) and leave the CPS window open.
3. Launch HxD, Click “Open RAM” and click on “mototrbocps.exe
4. Next, press control+R (or edit > replace)
5. Enter your current band limit (e.g. 450.0000) on the first field .
6. Enter your new, desired band limit (e.g. 420.0000) below.
7. Keep “datatype” at text-string, check the “unicode string” and “all” boxes, and click “Replace All”.
8. Click on “Save” (in the HxD utility).
9. Return to your open CPS program, change a few fields and make sure the changes took affect at the “device information” page (note the new split – 420 – 512 MHz!)
10. Pay attention! the next step is to edit your channels / frequencies AND SAVE THE FILE under a
new, different name. This saved file will now ALWAYS have the modified band split and should be
used from now on instead of reading the codeplug from the radio !
11. PROGRAM THE RADIO, TEST AND ALIGN !

Any attempt to read the radio will result in the deletion of all “out of band” frequencies in the radio. It
will not be bricked, just the information would be lost. Use the saved file to restore the radio if this
happens.

Florida Hams Prove that Ham Radio Works When Cell Phones Don’t

Florida Hams Prove that Ham Radio Works When Cell Phones Don’t

03/06/2013
After a day of exploring the Green Swamp Wildlife Management Area — which covers 50,692 protected acres in Florida’s Lake, Polk and Sumter Counties — with his grandson, Joe Cody, KE4WDP, of Winter Haven, Florida, saw that the roads were flooding and becoming hazardous. As he tried to drive out of the area, Cody’s small pick-up truck got bogged down in the mud. Since he was out of cell phone range, Cody tried calling for help on the Dade City 146.880 repeater. Richard Parker, KF4ORW, of Dade City, Florida, heard the call and answered.
After hearing the situation, Parker called 911 in Pasco County, who put him in touch with the dispatch in neighboring Polk County. Cody passed his location on to Parker, who in turn passed it on to the Polk County Sherriff’s Office. “Polk County 911 took over trying to get help,” Parker said. “They called me back several times for more information and I was able to relay information from Joe to them. Then Ted Bulmanski, W4TKB, who is also from Dade City, started monitoring and copying Joe’s information.”
About 30 minutes later, Parker saw a helicopter fly over and around Cody’s position, and after another 30 minutes, Cody radioed back on the repeater, saying he was on his way home — thanks to a Lake County Deputy in a Sherriff’s Office truck that had a winch. “We learned that Joe was eight miles inside Lake County,” Parker explained. “That’s why the Lake County Sherriff’s Office responded instead of the Polk County authorities. The Polk County Sherriff’s Office called me back to say that the helicopter from Lake County found the truck inside Lake County and sent both a deputy from Lake County, as well as a Fish and Game Officer and winched him out of the mud. They called me back to thank us for assisting the stranded pair. Ham radio still works when other forms of communications don’t.” — Thanks to ARRL West Central Florida Section Public Information Coordinator Kevin Poorman, KV4CT, for the information
