    Your cutter is dull or not set properly as you had to cut the insulation separately. If correct the white insulation would have been cut correctly. Also you should leave a bit more copper conductor as that was pretty short and the crimp may be missed.

    I've had so much trouble finding proper instructions for coax strippers. For example, the online Jaycar catalog, there was no manual, no instructions, no info on the manufacturer, just the description: "Simply rotate the stripper clockwise around the cable 3 to 6 times." It's been the same Mouser, Digikey, Cinch.... To make matters more difficult, I want to make cables with RG-316DS, which isn't nearly as common as the thicker cables. I had ordered one of these tools (before seeing this video), and had no idea it was intended to be opened.

    It's unfortunate that I see a lot of fire service utes having quarter wave aerial installs very much setup like the worksafe ute when firefighter comms are mission critical. Part of the problem is that the manufacturers themselves provide all sorts of brackets for their ground-dependent aerials that allow them to be bolted on to the sides of vehicles.

      Yes, GME and RFI are easy to use. You will need to purchase a step drill for the hole. I find the Hi-Tec base clunky. You will be tempted to use 3 PK screws which don't have much hold. The Pacific base will melt if you apply heat from your soldering iron for too long. I have two types of Pacific collet fittings. One type with a thread that does fit GME/RFI. The second type with a much more coarse thread.

  • @rkaag99
    @rkaag99 4 ปีที่แล้ว

    I'm not a certified pro or anything, but it seems to me that this is just the FM capture effect, especially with the proximity of the test gear. The analogue radio is jamming the signal enough to corrupt the digital stream so the audio simply shuts down, however I think it would equally impair another analogue radio as well. While analogue would not go quiet like the digital radio, it would likely be unusable. With some separation, some error correction might help the digital signal vs analogue under the same conditions. What do you think of this as a possibility?

      A good option if you don't have a VSWR meter or the skills to use one (I'm assuming you mean the CD29-138166, or similar). At least they are ground independent, so you can almost mount them anywhere (even inverted, provided you seal up the MBC fitting). On the down side the MBC fitting requires a soldering iron to terminate, and ideally a short piece of marine heat shrink to seal the RG58 cable. Both jobs are sometimes problematic to achieve in the field. The CD 29 antenna's also have less gain (less coverage area and shorter range) than a correctly tuned (trimmed) CD28 series antenna.

    • @rtguy1080
      @rtguy1080 4 ปีที่แล้ว

      CTCSS tones don't cause blocking. The receiver squelch will simply not open unless the correct tone is apparent. FM signals will have capture affect (strongest signal wins). You can also have a beat note (difference frequency) on top of the audio. This issue is different again. I believe the data packets (generated by the VOCODER) are being corrupted during transmission (by the analog signal). The DMR receiving radio appears to be quite sensitive to this form of interference. I believe the errors reach a point where forward error correction is defeated and the DMR receiver simply wont work. Its not good when this occurs right in the middle of "mission critical" communications (as the video demonstrates).

The cause of this "blocking" was tracked and found to be an analog radio (with CTCSS) on the same frequency (on an adjacent industrial site). The situation created a serious health and safety issue. The analog radio users had no idea that the digital users were present.

    I have just run this test. I used a Vertex Standard EVX5400 and a Radioddity GD-77 as my DMR radios and then used a Baofeng UV5R as the alalogue FM. Analogue power 5 watts. Radioddity 5 watts. Vertex 50 watts. At close range, 1m - 2m, blocking DID occur. At 10-15m, blocking occured about 50% of the time and at 15-20m blocking was rare. It did seem that blocking of the digital signal was more likely to occur when the analogue transmission had already commenced and that the digital signal was less likely to be blocked when the digital transmission was underway before the analogue. Interesting stuff, and it certainly warrants further investigation. My "interfering" analogue radio was only 5 watts. I can imagine that this issue could become quite serious as you suggest when a nearby station is operating higher power or directed signal. I wonder whether similar results would occur with P25, Fusion, etc?

Move the analog mobile radio progressively further from the two digital radios. Please post the result for everyone to see.

    I think your point is very clear however have you conducted test with varying levels of unwanted RF, eg the analogue signal. The proximity of the handheld in relationship to then 2 mobile units being very close, which would amount to some degree of swamping. I would suggest trying this same test with a signal mixer into the receiving mobile RT and inject via a hybrid coupler an analogue signal of a level that would be in line with a real world scenario. It would be interesting.

      Actually what I replicated on the bench, I discovered in the field after a customer complained about missed calls on his new digital radio. The analog radio (that caused the problem) was not even licensed for my district. My customer was using the digital radio for mission critical communications. The analog radio was several hundred meters away on an adjacent (and secure) industrial site. I can assure you that "swamping" was not an issue. Altering the colour code and privacy settings had no effect in the field or during subsequent experiments on the bench. I encourage you to do your own tests an add comments on your findings.
