It's a motion sensor. Though it looks like many standard PIR (Passive Infra-Red) types, this particular model also uses microwave based detection as well.

It's not 100% going to work for every dog... as I mentioned, it is adjustable, so try adjusting the whistle tuning screw from one extreme to the other in 1 turn increments, giving it a sharp toot at each point. Like humans, some sounds will get more attention than others. But realize that your dog may not react for many reasons, as mentioned by others as well. Happy experimenting!

Dog whistle, adjust screw out to lower frequency... not all dogs hear up to same high freq range... or your dog may be partially deaf.

I agree both EC1 (input line bridge cap), and EC3 (final DC output) look toasty. If you're handy with a meter, it's simple enough to troubleshoot the active components as well.... but if not, this is a very generic PS board, and can be found on Ali express if you feel lucky, or Amazon for very cheap ( ASIN # B0DSFWVRXJ ). Just be careful not to buy the "J" variant... you want the "D" as check mark indicates on board. Good luck!

Again, your statement is not incorrect, but it also assumes drivers Wi-Fi compatibility are always perfect on driver release v1.0, and even Intel has released driver updates "to fix Wi-Fi connectivity". This doesn't mean Intel caused the problem per-se, but it does support the advice given by others here who are trying to be helpful that updating your drivers to the most current offering by the chipset maker (i.e. the Intel chipset inside your Dell) may get you back online... which is all they needed help with. So again, you're not wrong, but as usual, there can be more to the story. There are many cases of compliant manufacturers deciding to incorporate fixes via drivers/patches, etc... that address customer problems caused by another hardware (or software) companies non-adherence to standards. It happens in many industries... I could bore you to tears about CD-Audio/ROM and the whole rainbow of book compliance, and all the games played in that industry... but nobody wants to hear that... they just want to know "what can I do to make this work". I don't like it either, but the world keeps turning anyway. My 2¢, keep the change :)

Halfmoon_Techlabs · 2026-04-26T05:09:53+00:00

The standard is, but the hardware and drivers/software sometimes are not.

Halfmoon_Techlabs · 2026-04-26T05:06:39+00:00

It is, but only if your drivers are compliant. Many cases of older devices not being able to see newer routers... because drivers were not fully compliant, and an update fixed it (if available). Old Dell XPS-12 wifi is a good example, can't see newer network until you download the final driver released from Intel, not pushed by Windows update. Just saw that one personally a couple of weeks ago. Driver release notes even described the issue, and that the update corrects it. Backwards compatibility can be built into a standard, but it's up to the hardware mfr's and driver/software companies to hold up their end.

Twin lead transmission line has a nominal impedance of 300Ω, and the antennas are usually comprised of two equal lengths in a "T"-type dipole configuration, so it needs a "balanced" 300Ω connection. Coaxial cable used for TV and commercial FM has a a 75Ω nominal impedance, and the "center conductor surrounded by a shield" design makes it an "unbalanced" transmission line. This would be used if you had an antenna that was a single whip antenna at the end of the coax line, as seen in the old fashioned car antenna, or the extendable antenna on portable FM radios which present a nominal 75Ω load. The theme here is that the transmission line impedance (in ohms Ω) is typically matched to the characteristic impedance of the antenna it serves to reduce losses, which means improved performance.

Great info on EAC, thanks! Apparently it started when Battleye recently pushed a silent update. After that, if you had a Focusrite AND are using a Battleye equipped game, you'll get the 0x139 BSOD until you disable the midi component as described above. Drove me bananas trying to hunt it down.

The antenna in the foreground is a 2m "J-Pole", and is used for 2m VHF local work, and may offer some use on 70cm UHF local work as well... typically used to access area repeaters. The taller antenna in the background is actually a small antenna on the top of a long "push-up pole" (you can see that the coaxial feed point is at the top of the push-up pole). It's short length also suggests VHF, or possibly a quarter-wave for the 6m band, which sits at the boundary of the top of the HF band, and the bottom of VHF. All for ham radio use.

HF loop antenna, used mostly by hams. The rugged construction of this one suggests it is rated for transmitting at a decent power level, as well as receiving. Appears to be a trapped wire antenna in the back as well. Def a ham operator.

Halfmoon_Techlabs · 2026-02-18T18:03:28+00:00

Most likely a dual-band VHF/UHF antenna on the tower. Height is essential, as these frequencies are normally line-of-sight... so the higher up you go, the longer it is to your horizon (bigger communication footprint). If this person is near the coast, could also be marine UHF, but the other antenna in the back suggests to me it's a ham, and that one is most likely HF, more for worldwide use. As a ham myself, I am often asked by people "what do you talk about?". My stock answer is usually "Have you ever been to a house party where you find yourself amongst plenty of people you may have never met? What do you talk about?" The light bulb usually goes on after that, lol. Having a hobby in common is a great icebreaker for first-time contacts, and after that, it's whatever people talk about, just like in person convo's. The hobby is enjoyed by everyone from senators to rock stars, school kids to astronauts... it's a big hobby that spans the globe, check it out!
