And if you choose to jumper N1 to N3 or yank F42, I thought I read where the main battery tray will accommodate a larger series of battery. That seems like the best final solution getting the dinky battery and ESS circuit out of there and putting in a larger capacity main battery that should...
But, but... my user name is from my local radio station I listen to here that plays nothing but 70s disco. What does that have to do with ham radio or GMRS?
;)
Yup, this is exactly how this works. You can select any Midland privacy code and I can still hear every word you say with a $14 bubble pack radio set for no privacy code.
You only have to identify your station every 10 minutes of talk or once if you make a single call. Anybody can "steal" your callsign and do what they want with it. You are not liable if anything bad happens from that. I've heard of it happening on amateur radio which you have to study and take a...
On the ohmmeter test if you measure less than an ohm consider it a short. When the antenna is screwed on you should show a short between the whip and coax center conductor. My test was to slowly unscrew the antenna and see how many turns you can go before it looses continuity between the whip...
Encryption is not legal to use on GRMS or FRS, that will get you noticed and turned in fast. I can also tell you first hand that if you cause enough problems on GMRS the FCC will visit you.
The height in the last picture looks ok to me. If you have an ohmmetter connect it across the coax center conductor and whip then check continuity while you unscrew the antenna off the mount. If you get two turns or more before it looses continuity it should be ok.
Some antenna bases have a...
To test antenna VSWR you put the meter in line with your antenna. To test radio output power accurately or at least to the extent of the accuracy of the meter you replace the antenna with a 50 ohm resistive load right at the output of the meter. Testing power when connected to the antenna might...
Even measuring a CB into an antenna will give inaccurate power readings, all wattmeter's are calibrated for use into a 50 ohm resistive load and when the load is a different resistance or impedance or has capacitive or inductive properties which antennas have, the meter cal is out the window...
I've never used that brand or model but its probably ok for the price. I would recommend a good 50 ohm resistive load rated for more power than your radio puts out. Any power measurements will only be accurate when using a 50 ohm resistive load and measuring power to your antenna will cause...
If your referring to the NMO thick mount I have used them many years ago and that particular one is made by Larsen which is good quality. Two things that need attention on that is the height of the center contact on top which you may have to adjust using a big washer or two on the underside of...
Wow. So I hear there is a radar in this unit and the 76GHz range is set aside for vehicle collision avoidance. Picture #3 in the post above appears to be a phased array antenna and if for 76GHz that would be very impressive. Not that long ago just this module would have cost more than the...
The steps in a step bit are really shallow, you might need to go about 3/8" wider than the hole to make a rectangular recessed spot for the back side of the NMO mount to fit in. I did that once using a hand held grinder in similar thickness metal to the Evo mount and it was a big PIA. If you...
I would try the Evo mount on the passenger side with a 3/8-24 mount and the Stryker antenna. Its not optimum but it will be easy and you will get a signal down the road. Since an NMO will not work with that mount there is still a trunk lip NMO mount for the GMRS antenna on the drivers side hood...
Its not out of the question to make a sheet metal ground plane for a UHF antenna sitting on a rack but not really for CB. When our local fire dept went to UHF in the 1970s they had the antennas mounted to a 12" dia round disc for a ground plane, elevated above the open cabs (this is sunny So Cal).
If you put an NMO mount in the fiberglass roof and make an aluminum tape ground plane on the underside, the NMO mount will bite into the tape on the underside and make good contact to the ground side of the mount. The hood is a lot of sheet metal and makes an adequate ground plane for CB if its...
Some people have put CB antennas on raised mounts above tire carriers with no sheet metal in sight (which don't work) and something like that would benefit from some clever ground wires. Since RF ground currents flow from the antenna feedpoint you want a ground plane to be electrically connected...
I've seen mounts similar to the Quadratech but with at least two mounting bolts and I would put it a little further towards the rear of the hood. The ground plane should be sufficient for a CB antenna and it should tune up ok there. I'm not a fan of that location for a UHF antenna but it will...
