Do you hear a repeater tail after you key up? Sent from my SM-S901U using Tapatalk

Legally/technically.. you would need a FCC approved device for each service. 1 radio for gmrs/frs 1 radio for amateur uhf/vhf 1 radio for amateur hf ( they have base stations that do 2m/70cm and hf) 1 radio for cb 1 radio for public safety 700-800 Yada yada and so on. Fun part most antennas can't do multi services well either. Sent from my SM-S901U using Tapatalk

No. Sent from my SM-S901U using Tapatalk

Whatever antenna you choose. You are going to want it roughly 100 feet up. Make sure there is nothing in the way, you will want to try to clear as many trees, hills and buildings. The less obstructions the better you are. Really helps if the repeater antenna is just as high or if not higher. Sent from my SM-S901U using Tapatalk

Gmrs is 462-472 mhz.. so yes unless you mod the radio all you can do is listen to the gmrs bands. Sent from my SM-S901U using Tapatalk

Don't think by default the 60re can transmit on gmrs. Not at least without a cap mod. Since it is amateur radio ht. Not a gmrs ht. EDIT: yup just confirmed transmit is 430-450 uhf and 144-148 vhf. Ham 2m and 70cm bands. Sent from my SM-S901U using Tapatalk

Could try a piece of vinyl wrap. Apply to the area on the car. Then place mag mount on it. Damn I wish I had tried it on the burb. The mag mount left a rust spot on the roof. It attracted iron from the debris on the road and that started to rust. Remeber dirt has iron in it. Don't believe me go grab a magnet and rub it on some dirt. Sent from my SM-S901U using Tapatalk

Frs/gmrs 4 is interstitial at 462.6375. Frs/gmrs 18 is 462.625. Shouldn't really hear them unless one of the following. 1. Horrible rf control by the radio. It shouldn't be spurious emissions, since spurious are usually harmonics. 2. Some is using a something like an unlocked non gmrs baofeng on frs 4 and didn't set the channel to narrow band. Set it wide and you would here some of the garbage on adjacent frequencies. Although it would be muffled and sound like garbage. Since you are getting some but not all of the carrier. Unlikely. 3. Most likely some radio on ch18. Roger beeps, clear to talk and all that crap are on multiple radios outside of frs. Remember the frs/gmrs rules were changed a year ago. So all but the repeater inputs are now shared. Sent from my SM-S901U using Tapatalk

It's all about the duty cylces. If you talk for 5-10 minutes keyed, issue. If it is 1-2 minutes of key time, when you talk and let the other person talk not so much of an issue. Sent from my SM-S901U using Tapatalk

Both the 778uv and db20g/779uv get quite warm on rag chews. The db20g/779uv are passively cooled. Don't use it enough to have it shut down. That is what the Motorolas are for. I do have about 5 friends that have added pc fans to the 778uv. Since they would get hot enough to clip or even shut down. Sent from my SM-S901U using Tapatalk

Pretty much. Just different firmware. The retagged anytone at-779 is the same radio with a different sticker. I have mine unlocked. (Softwares unlock and easy) Anytone is version is usually cheaper. Most places sell it under $90 usd. Both were tested by the same corporation in China and same person. Sent from my SM-S901U using Tapatalk

A lot of ghost/stubby antennas are loaded coils. So efrectively more coil than antenna. All the ones I were looking at where essential 5/8ths antennas and the gains would match with a standard 5/8 coil nmo antenna with appropriate matching assembly. Funny enough they are almost the same size. The ghost antennas were a tad shorter. Sent from my SM-S901U using Tapatalk

I usually put the loop at the lowest point before entry into the house as a drip point. Outside that pretty well covered. Good catch I neglected feed line loss without some swr and power level readings it could be very well be part of the problem. Sent from my SM-S901U using Tapatalk

Outside of clearing the trees. You could try a quality yagi and rotator. You will be giving up omni directional gain for a concentrated beam gain. So much so it's often worth putting a yagi up with an omni directional antenna above it. 2x coax and a switch at the bottom in the shack. Unfortunately, not many remote switches for gmrs frequencies. The beam will also act as a groundplane for the omni when done right. The pine trees will still hamper things. Another thing to try is a pre-amp. Not sure why you can get hin with your hand set but not the base. Should be the other way around. I mean you are on the ground with the hand sets. Something isn't right with your base by the sounds of it. Sent from my SM-S901U using Tapatalk

It is really no different then cb. Just really the wavelengths. Hence why we jokingly call it uhf cb. Hopefully, it doesn't get as bad. Yes you can mount two gmrs antennas on the same plane. I would recommend unplugging (antenna port on radio) / turning one off when the other is in use. Rf will still leak into the other radio's finals. 11m/cb is not a damaging harmonic (not even sure if it a harmonic, to lazy to check) of 2m/70/gmrs. As long as the antennas aren't too close shouldn't be a problem. My 11/10m antenna is on the rear hatch (driver side of hatch). The 2m/70cm on the hood and the gmrs on the center rear hatch about 3 ft from the cb antenna. Never had problems with it even when using 10m at 50w. Sent from my SM-S901U using Tapatalk

Randy do you have a term for a salty GMRS user.? Way too many coming out of the woodwork nowadays. Sent from my SM-S901U using Tapatalk

Military use it to give a signal report. Or the pilot on the drop ship says it to let you they are in the pipe and have a nominal profile. [emoji854] Sent from my SM-S901U using Tapatalk

I should add I have a ham radio with the antenna mounted almost in front of the driver on a hood hinge mount. The other antenna for gmrs is about 9" in front of the rear hatch on the roof. Roughly about 6 feet of separation and not even on the same plane. Welp, I have blasted the ham radio with the gmrs radio and vice versa, remember 70cm is real close but far also from gmrs frequencies. The Yaesu xtm400 (ham on fender) doesn't seem to care when I use the 70cm portion on the Motorola xtl5k (gmrs and ham p25). But the other way around the Motorola gets pissed (overloaded). It seems the Motorola is a lot more sensitive than the Yaesu. So normally I shut down the Xtm400 when using the Motorola and vice versa. Makes sense to me about the sensitivity. I mean new the Xtl5k were like $3k new and the Yaseu was about $500 new. Curious to see if the Harris 100m is going to be the same situation. Especially, since the harris will be on a triplexer with 3 different antennas. Sent from my SM-S901U using Tapatalk

Yes, it could. Especially, if the frequencies in use overlap or are harmonics. Even if they aren't overlapping or harmonics of the same frequency, the fact they are close to each other will effect performance. Rule of thumb is try to keep separation of antennas at least one wavelength apart of the lowest. You won't really know the effects till you try. Sent from my SM-S901U using Tapatalk

Illegally yes. Unlike ham, gmrs repeater pairs are channelized and the repeater pairs are pre-assigned. This includes input and output frequencies on gmrs. Someone tried it locally by reversing a repeater pair. Which on gmrs is illegal. You can, run into a host of issues. One of the big ones is looping between the 2 repeaters, until one times out or burns up. Whole host of reasons not to. Usually, easy fix is get the antenna about 100 feet up in the air (tower, tree, building) clear of obstruction. Then you'll average 12-18 miles of foot print (give or take 35 watts). Of course, mileage will vary with terrain and with repeater wattage/equipment. May I ask what spurred this thought process? Sent from my SM-S901U using Tapatalk

Use the equipment regularly. That way you will understand what works and doesn't work. Watch videos/research on questions that may arise as you use the gear. Rinse and repeat. Sent from my SM-S901U using Tapatalk

Good to know Sent from my SM-S901U using Tapatalk

Yes aluminum will work as a ground plane. Just not with a magnetic nmo. The foil is non ferrous so the magnetic nmo won't adhere thus no real capacitance. There are plenty of guys running around with drill through nmo mounts on aluminum surfaces. Hell alot of antennas are actually made with aluminum. Most common being tv antennas.

If you could get the repeater high up and close to the edge of your coverage, then you could theoretically double your range. As far as the second question. No. Anyone with a scanner can find you. Anyone with a frequency counter, sdr or just plain radio could find the repeater. Any radio that could listen to the frequency (has it in its frequency range) with a tone decoder. Could decode the pl.. You want privacy and encryption. The commercial license and setup are probably going to do what you want. Sent from my SM-S901U using Tapatalk
