Thanks I guess. lol... If the Ameritron 8v was rated to more the 250 Mhz. This thread would not exist. Might contact Ameritron to see what the VSWR is like 250 MHZ up from the rated 250 and 1.2. Might be the turn key reasonable priced option I was looking for.

Kinda a big worry. I contacted an Ebay seller of ip addressed wifi remote switches. I asked to see if he had anything spec'ed for DC- 800Mhz or so. Keeping fingers crossed. I guess I was hoping for a diy kit I could modify with different relays so the losses and the cost wouldn't be obnoxious. Either case starting to lean to surplus 12vdc radial (nominal 10vdc-14vdc) coaxial switches. Then i can simply it power it from the power supply of the radio. Should be an costly learning affair.

Biggest problem with some of the used gear is finding diagrams to help with pin outs.

No clue what the difference is between that and a transfer switch. Hell not 100% positive on what they mean when an ad says its a transfer switch. Just kinda figured it was a mechanical latching style switch. Might just be overthinking it. To the point, I also noted most almost all the transfer switch default to port one.

Yeah that is what I figure. They seem to be straight forward. Staring at more that have a db9 or that style connector. Since it will be much easier to source and rig a serial connector to cat6e with a straight patch or simple soldering. With some of these connectors it might be a complete pain to locate. Been Eye balling this one Another one I have been looking at. It looks even easier to wire up. Please feel free to pick up anything you locate. I am still deep in research stage, with a while to go before I even start experimenting.

I have been looking at surplus switches on ebay. I would need to figure out the controller as well It is one of the more viable options. Sent from my SM-S901U using Tapatalk

I would. But drilling through 3 floors (2 being hardwood flooring) might make the xyl more upset then the coax. Lol Sent from my SM-S901U using Tapatalk

I have a Diamond X200a in my attic for 2m/70cm fm operation. Was given a 7 element DIY GMRS Yagi. Which will have to go in the attic also, because of the HOA. i was investigating remote coax switches to limit the runs of wires going up the side of the house. Don't want the HOA to have a reason to poke around my house and see my bird stoop random wire antenna. I was planning on mounting a horizontal polarised 3 element 70cm yagi, a 3 element horizontal 2m yagi as well as the GMRS yagi. With a possibility of a fan dipole for hf. However, on investigation there aren't many if at all off the shelf remote coax switches that support vhf/uhf/gmrs frequencies. Most are HF or SUHF (silly expensive). Gonna be hard to explain why I have up to 4-7 runs of coax and control wires etc. Going up the side of the house. It's ugly already the way it is with one run of LMR400. Diplexers are kinda out due to the fact that i would need so many of them adding to the cost. I thought about buying a DIY switch kit on ebay, modifying it to use CX-140D (silly expensive, cost about $300 aprox $70 each just to cover the uhf/vhf ). Really not sure if I have the skills or thought process to do this. I should mention that the current coax line is DC Blocked at the lightning arrestor. So using coax as a control channel will not work. Any ideas or suggestions on economical ways to do this?

Nanovnas are awesome. Especially, when building antennas. But overtly complicated for most. They do have some what of a steep but fast learning curve to them. Most just buy a surecom, really more then enough. Fairly fast and not complicated. If really serious, you start looking at rigexperts and up. But they are $$$. Sent from my SM-S901U using Tapatalk

Part of the reason i love the Harris 100p. 2 check boxes and it won't affiliate or transmit on, said said trunked sets. Unlike some Motorola radios that will try to affiliate if you don't do it right. Then the radio will get zapped, to get it working again the system admin will have to unlock it. But good luck on explaining that and not ending up with hefty fines, the middle finger or some potential jail time. Better to get a scanner for the cost they are awesome. With a GMRS radio you are set. Sure you gotta carry 2 radios, but for simplicity,cost and legality wise it is going to be simpler. Really, wish there was ham gear that could do p25, trunked work. But it would be low volume. To be fair how many repeaters would even ever be set up for trunking? Yep, that is the answer I came up with.

Not really any issues but wear and tear and the cost of the installs on each vehicle. For the battery charger issue, might want to contact midland to see if there would be an issue. Really wasn't designed for the way you want to work it. I thought something similar using an xts5000 hand held, several XTVA units (dock for the ht) in different cars. Problem was the amplifier, it just got expensive. It would of been cheaper to have a anytone 779/radioitty 20g in each car. So there are several ways to skin the cat.

Normally, you do need 2sdrs. One for control and 1 for scan. Always thought the duo was built for contesters. Kinda gave it a glancing thought for trunking work. But then you are getting into sds100/g5 prices. Frugal radio on YouTube setup trunk tracking and scanning with 1 rtlsdr (cheapest option I know of). Sent from my SM-S901U using Tapatalk

Have you unitrunker? How is it? I recommended giving it a try to someone whom was trying to listen to p25 and dmr trunked systems. Out of of a lot of the software that was kinda free it had something that had something like a GUI vs dsd+ (I think that is what it was called). Sent from my SM-S901U using Tapatalk

Sounds like you will be upgrading the jeep again. Maybe the new one with the fully floating rear axle and a diesel.. lol Sent from my SM-S901U using Tapatalk

Actually, Marc ever thought about a small trailer with a motorized trailer dolly? Only since you do the events so often? Sent from my SM-S901U using Tapatalk

I get you. Too bad setup and breakdown probably took as long as the event. Looks more like a welcome tent then aide tent. Lol.. Love it though. Sent from my SM-S901U using Tapatalk

Wow. If it was me it would be a military load bearing backpack, a radio, golf umbrella strapped to the backpack. Cooler in one hand and a small generator in the other. I would of looked like a hobo pervert watching the runners go by. Sent from my SM-S901U using Tapatalk

Looks like it isn't trailer accessible. Do you guys lug out all the gear in a wagon or pack mule like a bernard? Sent from my SM-S901U using Tapatalk

I have had several head mri's. Couldn't tell you what they sound like. Was wearing ear plugs, still defeaning. When people ask I don't know, like putting you head next to a jet engine with rocks in it?! Sent from my SM-S901U using Tapatalk

Try unplugging the mic and make sure it seats properly. I have had problems with rj11 and rj45 connectors with boots. Where they aren't fully seated and the mic acts funny. Sent from my SM-S901U using Tapatalk

Awesome. I don't see the fridge. Hydration is important! Sent from my SM-S901U using Tapatalk

You could build a low power repeater. Problem will be you will need an indoor and outdoor antenna. When the repeater transmitting. You will lose half of the power to each antenna. Plus a mess of other things that could go wrong. I had looked at passive repeaters/antennas. But the usefulness of them are low. In your case. I would investigate this an option. Don't expect much, but to spend money. You could try to build a dipole indoors connected to a yagi outside pointed at the area of intrest. But again passive repeaters aren't in high use for a reason. Another option is to get a kg100g, or any radio with a Bluetooth option. With a Bluetooth mic and connect the kg to an external antenna. For hams, I have contemplated buy a uv578 with Bluetooth head control mic. But always just walk over to one of my digital radios and use the hotspot. Haven't seen a gmrs (tuned) hotspot yet. Guess that will be on a to do list. Sent from my SM-S901U using Tapatalk

Using sdr console. It's a windows install. Ham centric. Little things like the pre-installed save for ham bands. The visual marker for saves etc. Lots of people like replay software. I didn't personally. Sent from my SM-S901U using Tapatalk

Bring the mic closer to your mouth. Some radios have crap mics or the hole needs to be drilled out. Some just need a gain adjustment to get the ideal deviation. How far is the mic from your mouth? What radio/hand mic. Sent from my SM-S901U using Tapatalk
