They use the 8000 series radios 8402 i believe. You can order the complete Maxon Service Manual for all Maxon radios on CD for $30 last i saw a year ago on RFWiz.com. I have read on Repeater Builder that Brifgecomm uses the actual 8402 boards so the xtmtr board should be the same.. I would get hold of a service manual to see if they are using two boards, may be one board with both XTMT/REC on one and they are using two to complete a repeater.

Bridgecom software is different (slightly) but Maxons software will still make changes.

I just got currious about anti-seize and pulled mine out of the cabinet to read. It's a copper base antisize recommend for electrical connections. I wonder if Comet recommends a copper base anti-seize to enhance the electrical connection with their antennas?

Yea, i have as well.. Water and moisture surelty contribute to the corrosion factor. About 10 years ago i restored a 1970 Yamaha 250 Enduro Motorcycle. It sat in my dads back yard for over 30 years. Many of the steel bolt used for the aluminum casing were seized with some destroying the threaded casing. The bolts that were steel to steel cam out with ease.

Cars and motorcycles do use dissimilar metals for fasteners and they also advise use of anti-seize. Also, dissimilar metals for fastening use does not promote the corrasion effect as much as it does when electrical current flows through the dissimilar metal.

I posted your quotes..

most antennas i'm aware of use aluminum for the radials and it's mouting and use SS for the actual antenna mouting hardwae, wo what you report makes sense.

no arguments on the quality or performance of the Comet Antenna..in fact im a bit impressed they arent taking shortcuts in material quality...

You should spend a little time and google this topic and possibly re-read my comment. Yes VHF marine radio is significantly affected byt the inoosphere, is it common, No but yes it does happen just as it does with Broadcast TV. Is it common at UHF NO.. You may want to go back and retract your statement, "30 Mhz will NOT reflect off the ionosphere". That my friend is defiantly incorrect. BTW, i wasn't calling you Bud. I was more currious if you were drinking BUD. Meanwhile here is a little bit you may find on a Google Search: How the Ionosphere Affects Marine Radio: High Frequency (HF) Radio: Marine radio communication often uses HF bands, which are susceptible to ionospheric effects. The ionosphere can reflect HF radio waves, allowing them to travel long distances, sometimes even around the world. Ionospheric Disturbances: Solar activity, such as solar flares and coronal mass ejections, can disrupt the ionosphere, leading to reduced or even blackouts of HF radio signals. Absorption and Refraction: The ionosphere can absorb radio signals, especially during periods of increased ionization density, and it can also refract (bend) radio waves, altering their path. Long-Range Communication: The ionosphere's ability to reflect HF radio waves is crucial for long-range communication, as it allows signals to be transmitted over distances beyond the line of sight. Daytime vs. Nighttime: The ionosphere's characteristics vary during the day and night. At night, the ionosphere can be thinner, allowing for more efficient reflection of radio waves, which can enhance long-distance communication. VHF and Higher Frequencies: While HF radio is strongly influenced by the ionosphere, VHF and higher frequencies usually penetrate the ionosphere and are more commonly used for ground-to-space communications. However, there can be exceptions, such as Sporadic E (E-skip) propagation, where VHF signals can be reflected by the ionosphere during certain seasons.

I'll be traviling to from that area in two weeks.. I'll keep my ears open too. Yes, either DMR or TRBO

I have never used a Comet antenna so i can't attest to their product. I have read good things though. I do find it odd they would use stainless steel radials compared to aluminum, mostly because of cost difference of material and the low cost Comet sells at. Is Comet also using a stainless steel base for the radial? if so, there wouldn't be an issue with dissimilar metals.

I get that.. I brought up 'Broadcast TV' in my comment as a reference to Marine VHF because Broadcast TV is VHF. Most of us know VHF Broadcast TV reacts to skip off the ionosphere like VHF Marine radio and UHF TV does not, so it was a reference. His first line comment 'Not Sure Thats Right' and the rambling after was a bit boggling.. Thats all.

Check Ebay,, they have a few advertised as fully tested and ready to shop.. Some are a bit pricey.. Check Surplus Two Way Radios as well.

what the hell are you saying there? sounds like 'Bud' talking. 99.9% of us would not argue that broadcast TV is oneway transmission and no way compares to a GMRS signal. We know that, why do you bring that up. Sorry, but i cant wrap my head around your comment. 'Bud' will do that sometimes.

exactly what i was thinking

Hmmm. As cheap as they sell the Comet i'm thinking the radias are made of threaded aluminium rod or tube.

Amazing to think about.. Here is a neat video, long but very interestig about communications to and from space

takes 20 hours to receive a signal from Voyager and the same amount of time for Voyager to receive a signal from earth.

But a hell many of stars.

what amazes me is how far we can communicate into space.. For example Voyager 1 is some 15 billion miles into space and we are communicating with that spacecraft to and from with ease.

the good ole days.

Real ones were so much better, it never entered your mind that the ones you were playing with could have been made in 'China'

I wouldn't consider the NEC a 'bare minimum' but more so of a 'standard' Some manufactures of electrical equipment may 'suggest' additional steps or recommendations beyond the 'standard' but defiantly not required.. However some manufacture may require their recommendations for warranty purposes but i dont know if any manufactures that do.

There is a very slight difference, one protects the welfare of workers while doing installations and includes certain electrical guidlines, whiel the other outlines the actual electrical guidelines.. One of these guidelines came before the other. I actually attended a class on this in 1986 and i still remember.. Do you know whichy guideline came before the other than adopted the one before? You might have to do some studing on that one. Carrry on

or the National Electric code is NFPA.. Read.. Carry on I told you at the end of the day we would agree, but stubborn you wanted to keep on arguing
