Hi all! So I want to run my vehicle on an ULF44. It’s going to be 4 sets of ions, each paired together and set to an output on the ULF44. I want the first function to be a flashing mode, and the second function (override) to be a slow flash for on-scene. One of the pairs of Ions is going to be...

Sooooo! Its been about two months. I was ready to pull my hair out. Tore into every bit of wiring and tried different size ferrites all over the wires. It worked for the front lights. The rear, not so much. My guess is that due to the proximity of the antenna, the actual light head was being...

Ordered the ferittes off Amazon. Prime is slow in my area so it'll be a couple days. in the meantime, I'll let you all know how changing the power works

I'm transmitting at 50 watts. I might try and switch to low power in the morning and see how that works. I'm really only using it for repeaters which are realitively close so hitting those with low power shouldn't be hard. The antenna is 3ish feet from the closest light head. The actual antenna...

That's an easy enough fix. I'm going to try this out and I'll report back. STL, although cheap, is pretty popular around here. I'm sure I'm not the only one that'll have this issue so when I find a fix I'll throw it in this thread for those behind me.

Also, I separated the grounds for the relays. Worked at first and I was happy because i thought it solved it. Next time I needed to used both at the same time (later that day), wouldn't you believe that it did it again.

I know it's the truth... I actually went that route with my last car, bought all used Whelen and outfitted it like that. For some reason I wanted to try the STL, if they crapped the bed it wouldn't be a huge monetary loss. In my area we use VHF in the public safety range, 150mHz to 160mHz...

Hey guys, Had an issue last night when transmitting. I've recently installed lights with an STL remote switch fob. Lights work perfectly on the pattern I selected for them (w/ momentary switch in key fob). When I keyed up on my TK7180 the pattern changed on the lights to an odd steady burn /...
