It is NOT the conduit punch look for a CHASSIS punch. Here is one : www.ebay.com/itm/395577747700?_skw=3%2F4%22+chassis+punch&itmmeta=01JK2BBHZVVJ7HMXVKWEP2Z8KS&hash=item5c1a4568f4:g:j-kAAOSwM21msUGF&itmprp=enc%3AAQAJAAAA0HoV3kP08IDx%2BKZ9MfhVJKnUfEfkul6L47PJTB%2B5T6Bj8mIxw9mxMSSF1Y3%2Fo766hwF3SzQjh5bxGxSdFBBWSrekHIZpfcYTQxZ4Aas%2F9NrnrNmhppPpvK%2B%2FOby3%2Bar3Rle8CEvycBOXonsJO%2B0ZSBXv6swUF3UhSLK1xM6itTywUV%2BZq8Bb7i9r2KvHpXDG9zqC3yhCEQRgZp%2BUP4uaqVaiqlKdPYhAIVmIxZmxferejJwrKOrLZNdKLvqkPw1XsLFduI4W7lB64yrHkQ7%2F840%3D%7Ctkp%3ABk9SR4igrsuYZQ

When doing a single port cable loss measurement typically the end of the cable being measured is terminated with an open at the far end ( Anritsu etc. - not sure about the rig expert ). Try to repeat the test with it open and see if the results are similar to the specification. Thanks for watching !

Thank you ! This one is still in good shape but it is more brittle now than they were when new. Thanks for watching !

I have done it several times. to saber and saber/ r packs . Take your time and work the bottom seam. It takes a while like a few hours . Cheap aftermarket packs come apart much easier than the OEM ones. Thanks for watching !

@survivalcomms And I got caught a few 0em Batteries that are dead .i Bought Some after market ones But. Some of them just do not hold a charge They seem to be junk .

@@joemazza1011 The aftermarket batteries are junk for these legacy radios - that's why I convert them to 18650. The only decent aftermarket batteries come from reputable vendors like tessco and even then its hit or miss if even available. Amazon and ebay batteries are to be avoided. Use the aftermarket ones for the housings.

I was there at the end of the Plano era before pelican drug boxes got popular. I am glad you are enjoying my content and thanks for watching !

The Starter , battery cables, and ground should be at least #4. The alternator I used 8 gauge for and every thing else I used 14 and 16 gauge. Thanks for watching !

One of the greatest difficulties is the lack of tools and equipment, and if equipment IS available, transporting equipment and manpower is a huge challenge. “Specialized” tools and even test gear will likely not be available for an extended period of time, so “alternative” and unorthodox methods are the way to go for now. The Heliax prep/stripping devices he’s come to rely on and use daily were lost, along with the majority of hand tools and small power tools. He reminded me of our early days as “cheap hams” before we entered the field. We’d bring a case of ice cold beer over to cell site installations in the area. (Always at the END of the work day! ETOH + Towers = Death)🤫 The refreshments and a bit of cash would usually result in us loading up our trucks with excess cable and parts. Back then, before the internet was ubiquitous, we’d have to figure out how to accomplish tasks by learning from the “Elmers” of our amateur radio club and experimenting. He is currently very happy to have retained many of those skills! Making use of general purpose type tools that (hopefully) can be acquired during an emergency or disaster, things like hacksaws/blades, utility knives/razor blades, etc…. will keep you communicating.

Some tips / ideas / experiences from a few “old school” radio guys (+ one who’s currently working the massive wildfire in the Los Angeles area. - When brushing the prepped Heliax center conductor (or any of the internals of the connector), please NEVER use a dirty/contaminated/steel brush. I once used a welder’s filthy old wire brush for dressing a huge number of 7/8” cable/connectors at a high RF density and very packed site. After PIM and odd problems suddenly appeared and RF engineers spent days evaluating, I was scolded and schooled AND had to spend days cleaning everything up. Tower climbing was also required ($$ !) as I had pre-terminated everything on the ground and “bagged” each end. Good tip = My boss used to carry tiny 8mil plastic bags to protect connectors during work and for any “spare” cables left behind. Just don’t leave on if left outdoors, water will always find a way in.

@@PowderMill The GI M16 brushes work good. Back in the day I would buy 100 of them for 20 bucks. Thanks for watching !

I can do that. I did another video with the newer positive stop connectors as well ruclips.net/video/SfSCEgsumws/видео.html Thanks for watching !

Sorry for the length of all of this,.. A bunch of us were on a conference call as I was typing this and figured someone might benefit from some tips. Not really a tip, but from our buddy in Cali: “While VHF (2m for hams) has its place for the more rural areas, handling duplexers and cavities makes you really appreciate the smaller size/weight of UHF and 700/800MHz equipment.” “We even have some VHF Low-Band (freq range in use = 38-48MHz) duplexers in service for OEM and CHP interop. They are the size and weight of huge 6’ tall oxygen tanks and there are a quite a few per repeater. Combiners/multi-couplers and engineered antenna systems are less common with the lower freqs, making relocating easier.” “I always carry a few ‘mobile’ notch type duplexers in the truck for field-expedient emergency situations. UHF / UHF T-Band / VHF High-Band / 700 800 900 MHz, with more UHF & VHF than the others because UHF works well and VHF is the majority of what the fire service uses out here. I can tune up a notch duplexer in under 10min and they are tiny enough that I can carry a dozen or more without using much space.” “The untuned ‘mobile’ duplexers really saved the day yesterday. While I’d never use one on an important project or system and always keep power at half of the 50w rating, they get you up and running in a pinch.” “Most ‘hams’ and GMRS folk are being sold absolute junk, actually “tuned“ in China, some supposedly tuned for use on any GMRS frequency pair , and wonder why their repeaters work the way they work.” “There’s a reason they’re called mobile duplexers, and I have learned from the radio techs working back when Johnny & Roy and EMERGENCY! We’re on TV. When MICU paramedics began operating, cell phones did not exist. There were/are 10 UHF “med channels” used. The hospital ER had entire work areas set up with tone or DC remote(s), used to control their rooftop radio equipment. The firefighter/paramedics would carry a /\/\otorola Apcor radio onboard their truck. It used the onboard gear to relay from their 1-2w Apcor to the hospital ER. They could plug their LifePak cardiac monitors/defib boxes right into the Apcor , enabling them to speak to their medical control doc and send EKG telemetry right to the ER.”

Thank you very much ! Thanks for watching !

It does .Thanks for watching !

No doubt ! Thanks for watching !

100% It is a real problem ! Thanks for watching !

Thank you very much and thanks for watching !

I was told 6k loaded. The only way to know for sure is to talk to the vendor. Thanks for watching

Yes this one belongs to a friend of mine who built it in the late 60's. You will see more of this tuner in upcoming content. Thanks for watching !

It truly is there is so much power for the price and form factor in a NanoVNA. Thanks for watching !

@ great video. We can “see RF Impedence” across frequency range in near real time. Walk by an antenna with a screen share to your laptop or bluetooth to RigExpert… and see that everything affects everything as David C says.

Thanks for watching !

Thank you ! Thanks for watching !

The HF bands. VHF / UHF mods for this radio do not exist. It is all in the video. Thanks for watching !

100% It's nauseating all of the auto tuner QRM that goes on over the air as well. I have a field notes for all of my manual tuners that has the settings for my various antennas to give me a starting point. The little NanoVNA helps me dial it in. Thanks for watching !

It works on 80 but not as well as a doublet. It will not match on 160 and I never implied it would. Thanks for watching !

@ in the video you mentioned 160 as being “ better than you thought it would be” guess I read a bit into that. By saying it doesn’t work as good as a doublet do you mean 60ft elements instead of these at 46ft?

@@forgetyourlife If you put 60 foot elements on it i is no longer a zs6bkw it is a doublet with a 39 foot feedline. on the zs6bkw the window line is part of the radiator. The 80m doublet is great but it is poor on 40m as a 40m doublet is poor on 20. Its the nature of odd and even multiple quarter wave relationships.

@@survivalcomms so if someone using this antenna also wants to be on 80m they should probably have a different antenna for 80m I take it.

@@forgetyourlife Use an 80 m dipole

Infrastructure independent the best option is to use HF with your amateur radio license on 80 60 40 or 30 meters using a horizontal antenna less than 1/4 wavelength over the ground at both points. Use CW (morse code) preferably early in the morning. Even then you may not be able to establish a talkpath. If you dont mind using infrastructure get your self a starlink mini , an analog telephone adapter with a telephone and pay for a voIP plan. You will have a phone number and every thing the internet provides. Thanks for watching !

@@survivalcomms thanks for kind guidance, Would appreciate if you provide more information on infrastructure independence communication

Knots are fun. Three half hitches stacked and tied in the SAME direction can get you out of most trouble and never tie a knot you cannot untie. A knots video is a great idea. I actually have a card game where you draw a card and have to tie the knot on the card. That is one of the best ways to learn a family of knots. Thanks for watching !

@@survivalcomms And if you do a video on knots, make it SurvivalComms related stuff, e.g. "I just threw a line in a tree to support an inverted V antenna. How do I ..."

Thank you ! Thanks for watching !

3 hundredths of an amp in this case should last 90 days of storage not taking self discharge into account . A lead acid battery in Florida heat can self discharge 15 - 20 percent capacity on average sitting on a shelf which is 2 hundredths of an amp if my math is right. I need to drive the vehicle more often :) Thanks for watching !

23 mils won't drain it in 2 weeks. Most cars have closer to 75 mils and even that isn't a problem in 2 weeks. If you leave it 3 to 4 weeks just plug in a small solar trickle charger to the car via a tap in the interior fuse panel.

Yes it is the chassis punch . It makes the cleanest hole for an NMO mount by far. The purpose built " antenna " hole saws antenna are a jagged mess by comparison. Thanks for watching !

@@survivalcomms In order to fix this mistake, a fellow turned me onto a company called Breed Love. They make NMO mounts with very large bases, and ship with a thick rubber gasket for the top side. Worked like a champ, and the price was reasonable.

@@viewatyourownrisk Thanks for the info . I was checking them out and those would be ideal for those torn out NMO bases from impacts. Decades ago I put a hurst shifter in my car and cut an enormous opening in my floor board. I told the dude at the speed shop I needed a big shifter boot and he handed me one across the counter the size of a maxtrac and said " big boot for big problems " Thanks for sharing the info !
