Others may disagree, but the reality is that the English language is a very large and convoluted bunch of code words and phrases. One could simply agree on common innocuous phrases to have meanings such as "on the flop" - stopped, "on the fly" - en route, "on the fritz" - broke down, and as long as you don't refer to them in a cryptic fashion ("I send code "on the flop" to your station. I repeat "on the flop"! How copy? Over!!) no one is going to report you to the FCC for speaking in code...nor will anyone care enough, or listen long enough, to even understand that you are speaking in any "code" except English. What's more, if you stick to simplex your communications are unlikely to be scrutinized by radio aficionados or the FCC for codes any more than the lumber yard, the daycare, the garbage truck drivers, or the construction guys already transmitting code phrases on those channels.

That is alot of words. I may have skipped reading one or two as i really only use it for family comms. My official travel channel is whichever one we agree on ahead of a trip.

Thanks for posting the pic. That actually looks like a solid attempt at making a useful antenna (not that I am any kind of expert), and not just a placeholder. Your UV5R came with a Tidradio 771. My UV5R came with an Abbree AR 771. The only difference I can see between the two is the text and color of the print near the base. I am guessing both are knockoffs of the Nagoya 771. Perhaps they are built by the same manufacturer, and then private labeled. This actually is a question: What's in a name? Is the 771 designation just a model number that is being copied so that buyers associate the antenna with a model perceived as being good, or does a 771 have specific qualities related to the number 771 (the way a 427 engine has a bore and stroke that nominally totals 427 cubic inches)?

Breedlove has some nice mounts: https://breedlovemounts.com/store/ols/all I had their pedestal on my Jeep and recently went to a Breedlove stake pocket NMO mount on my truck. I ran a ground for each to the frame. Some folks may push for something more centrally located on the vehicle than a stake pocket, but both of my mounts work great for my purposes. The stake pocket mount with Midland antenna provided a SWR reading of 1.09:1 at the time of installation. I also considered a unit that mounts under the hood. This one is for a truck, but I have seen similar units on Jeeps: https://www.americanradiosupply.com/2009-2014-ford-no-hole-antenna-mounting-bracket-fo2antpf/?gclid=CjwKCAiAr4GgBhBFEiwAgwORrcL5fTOTcrk1nlGEvw0fyHiCLQmaZgWGCyVoMiOPU0BGY1X7zswftRoC7pcQAvD_BwE

I initially fabricated a mount, but when I saw this adjustable roof mount available locally at Home Depot for a reasonable price I decided it looked a little nicer: https://www.homedepot.com/p/Winegard-J-Pipe-Antenna-Mount-DS-3000/204701091

It looks like you must first set up a priority channel as described in menu option 21 (page 66 of the manual). https://www.buytwowayradios.com/downloads/dl/file/id/1540/product/5751/wouxun_kg_1000g_plus_owners_manual.pdf Once you have set up a priority channel, you can change your Key B assignment (Menu 63) to "Pri-Sel" to select your priority channel.

I suspect you still won't see huge amounts of RFI even on IP20 drives that are modern and sized and installed properly. Its usually when you see questionable installations, repurposed drives and enclosures, long runs of unshielded cabling without drains, poorly-sized drives, aging motor starters, dirty corrosive environments, or poorly maintained systems that things get fuzzy...but there is no shortage of those places. I have a customer that runs two 600hp and two 800hp electrically driven compressors built in the '60s (which are soon to be replaced by turbines). They produce some serious electrical noise. Fortunately for them, they have very, very few neighbors to complain.

No dispute from me. Solar installations are absolutely a possible source of RFI, and more and more common across the nation. With regard to VFDs, all VFDs produce some RFI no matter their country of origin. It is the installation (grounding and shielding) that mitigates emissions. Electrical contactors and cross-line motor starters with failing components can also produce RFI with no VFD present. For the OP, since it seems like a fairly widespread area of interference (assuming it happens absent the presense of your vehicle as Sshannon mentioned) it might be worthwhile to take note of any particularly large power transmission lines along your route. When time allows, follow them as far as they parallel your normal travel pattern on public thoroughfares, and investigate the locations of any large electrical substations where 14400 volts steps down to 4160 (or similar) to feed natural gas compressor stations, mining or foundry operations, or similarly large electrical customers.

Interference near a warehouse is not surprising as there are a myriad of commercial and industrial devices that can produce RFI, particularly in aging buildings. Variable frequency drives used to run HVAC equipment are a common sources of electrical noise. http://www.vfds.org/vfd-and-rfi-708163.html "The conclusion, later confirmed by the VFD manufacturer, was that the building, without a solid earth ground, was acting as an antenna."

Clearly I am responsible for causing this thread to take a downward turn, and for that I apologize. Since the US is neither socialist nor communist, I didn't, and still don't see that the content of the phrases that I co-opted into my signature temporarily were actually all that objectionable. MichaelLAX is correct however, that political statements such as the one I made, really have no place on this board. No one should be ignoring, blocking, or cancelling valuable input from others due to my poor judgement. Onward and upward...including the temperature please!

Don't go buttering me up just yet MichaelLAX, Though I am not unreasonable, I don't make a habit of kowtowing to the perpetually-offended.

My apologies if my signature struck a nerve MichaelLAX. I am not unreasonable, and since I value input from others I removed the offending signature in an effort to not be such a "bad apple".

You are right. My apologies. What can I do to help?

Hmm...my escapement mechanism is .45acp, which should conduct me to either my 12ga repulsion mechanism, or my .308 powered defeatment mechanism...which is only necessary if my avoidance mechanism fails. ?

That looks fine...though you might ask the maid to dust next time she is in. Also it might help to actually plug the antenna into the radio. Kidding of course. Here is my GMRS base. I don't have much more equipment, but I do have a couple of rooftop antennas to test soon. Looks like I need to dust as well.

In my experience, wheel-speed sensors and vehicle speed sensors are hard-wired components instead of radio...but my experience clearly doesn't extend to your van so I have no doubt that you are correct.

The source of the signal is clearly aliens. The signal is a countdown which will end on "Independence Day" ? Are there any large manufacturers or pipeline pump stations nearby? Light rail or hydro-power perhaps? What is your squelch set to? What happens if you try to communicate on a frequency exhibiting the noise from your HT to your mobile, or vice-versa?

Perhaps it is the tire pressure monitoring sensors. "TPMS sensors operate at one of two frequencies, 315MHz, and 433MHz. The frequency of the sensor used is determined by the vehicle manufacturer. " "In rolling mode, sensors transmit, on average, once every 30-120 seconds. While parked or in stationary mode, depending on the manufacturer, sensors may transmit only when a significant pressure change is detected. If a TPMS sensor transmitted all the time, a sensor would not last very long." - Stolen from Google

Lord knows I am not afraid to modify a house. I have perforated, ventilated, and fenestrated every wall repeatedly in years of remodeling. For the purpose of future portability, I am not sure I am ready to put in multiple stubs just so I can occasionally relocate my base unit. The more I look at these jumpers, the more it makes sense to utilize one for the current house, where the windows really don't get actuated often. The next house will get stubs.

Thank you fellows. I still have some concerns regarding longevity, but I think I will give the CTC-50M a try on my base unit. Here are a couple of other videos showing initial use of the the flat cable pass-thru. I haven't found any reviews that discuss how long the product lasts, or if it degrades performance. I will let you know what I find.

I happened across this window cable pass-through jumper (PN CMA-CTC-50M) from DX Engineering: https://www.dxengineering.com/parts/cma-ctc-50m?seid=dxese1&gclid=Cj0KCQiA_P6dBhD1ARIsAAGI7HA7gydQdcvavKhoxfEmf5r4LseuOXmH6mzKLW72iOy2W4H2pa1hZA8aAvtrEALw_wcB It's not hard to imagine that something like that might be more problematic than beneficial, and clearly it is a band-aid rather than a long-term solution, but I am wondering if anyone has used the DX engineering jumper, or something similar to the PaneRelief from QSRadio (below), and been pleasantly surprised at the results. Are they worth the cost...or more trouble than good? https://www.qsradio.com/index.html?~~mode=product&~~id=51822072

GMRS is a radio service for people who want to communicate while they are doing stuff. HAM is a radio service for people who want to communicate while they are doing nothing. HAMs on GMRS are people who want to live vicariously through people who are doing stuff, while doing nothing. I am kidding. I am truly thankful for all of the knowledge, experience, and information that generous HAMs have been able to pass on to me and others so that we can use the airwaves effectively. If not for them, we would all have to figure it out our _______ selves...or not at all.

Spectacular! I was too awestruck by your build (or simply too stupid) to notice that you went to the trouble of linking the components. Very commendable! Thank you Cactusboy19! (apparently my number of reactions today has exceeded the daily allowed reactions on this site, but I will come back tomorrow and "Like" this thread)

BOUNTY! The quicker picker upper! Just a reminder: Please pick up milk and paper towels on your way home. I hit the "Like" button, but it didn't register because I have apparently exceeded my allowed daily number of reactions. I didn't know there was a limit on how many beneficial posts I was allowed to react to...but there is. I will come back and like it tomorrow.

Excellent! Thank you for documenting it in pictures. I am sorry to be the munny-grubber but...approximate hardware cost? Any guesstimate on the expected range?
