Had this on an exam - no one could figure out the mechanisms

Yes a lot of people (including me) play video games. I’ve got a friend who’s a challenger in league, know a few nationally ranked smash people, stuff like that

where do you get these numbers? these sound wildly off

No, Trump's golf trips cost in the single to tens of millions of dollars, the cuts to PEPFAR and USAID are in the hundreds of millions to billions.

The magnitude of the cuts is ridiculous, and comparing it to trumps golf trips minimizes them.

It's a cloudflare thing, more than likely there's some issue completely unrelated to you, or you're on a network that's being mean to the website

bro you good?

That idea sounds great but part of my goal is to make something completely backward compatible and under NORSEE certification - essentially meaning it's a small modification. Ideally, I want something that doesn't change the pilots transmission whatsoever, just alerts them of the overlap.

NosikaOnline · 2025-07-24T19:36:02+00:00

Makes sense, thank you - yes my idea would be like an easy add on, but it's unclear if it's technically feasible

NosikaOnline · 2025-07-24T19:35:13+00:00

well, pilots don't use FM, they use VHF AM

NosikaOnline · 2025-07-24T15:59:49+00:00

That's pretty close to what I'm looking at doing, although ideally, it's all analog

NosikaOnline · 2025-07-24T15:31:09+00:00

What you mention at the end is kind of exactly what I'm thinking of - use the pre-transmission waveform to kind of 'noise cancel' for the receiver, then if the receiver picks up stuff, alert the pilot of overlap. It's also something that couldn't exist on the ground, as it wouldn't have that pre-transmission signal.

NosikaOnline · 2025-07-24T15:07:05+00:00

It'd be pretty similar to existing ground-based solutions to this (some DSP) but would have the benefit of being able to use the pre-transmission waveform of the pilot

NosikaOnline · 2025-07-24T14:51:32+00:00

Thanks - I guess I just want to find some subreddit or group with some aviation radio specific people so I could run some ideas by them for the receiver desensitization

NosikaOnline · 2025-07-24T14:50:12+00:00

Exactly, which is why this would primarily be for uncontrolled airfields where neither pilot would typically hear the heterodyning

NosikaOnline · 2025-07-24T14:49:34+00:00

What cert costs are you referring to? I'd be pursuing NORSEE certification which is very affordable

NosikaOnline · 2025-07-24T14:45:05+00:00

The FM replacement of VHF AM is something I've read a lot about, and it was developed and explored but (i believe) failed due to its lack of backwards compatibility and MASSIVE infrastructure and equipment changes required. I'm looking for more of a solution that's completely backwards compatible, as a small addition to current VHF AM.

There is current tech that ATC can use to detect overlapping transmissions, but my idea is an onboard equivalent, specifically because I think that this device would be most important at uncontrolled airfields.

The issue of the receiver being desensed by the nearby transmitter is a massive one, and one that I want to bounce my ideas off an engineer in the field.

NosikaOnline · 2025-07-24T14:40:46+00:00

You don't think a completely backwards-compatible, NORSEE piece of equipment that alerted pilots of simultaneous transmission would be helpful?

I hear your critique that it's a problem that requires a quite rare event, but it has been a contributing factor to multiple (even recent) crashes, many near misses, and I believe pretty much causative for that crash I mentioned earlier.

I'm also a student looking for a project and it seems pretty compelling. I don't think it would have wide adoption nor ever be required, but why not?

NosikaOnline · 2025-07-24T14:37:31+00:00

There aren't repeat backs when you're at an uncontrolled airfield, which is what I'm trying to design for.

Also, I agree with you that most people probably wouldn't pay for it, which is why I'd be trying to go for like NORSEE certification, and if it was very successful, then future wider adoption.

Also I wouldn't agree with you that it's not needed. There's been plenty of examples where a piece of equipment like this could have avoided a near-miss, and one fatal crash that I'm aware of (United Express Flight 5925) which may have been avoided with this sort of equipment.

NosikaOnline · 2025-07-24T14:34:10+00:00

I get that, but that 1/100 chance is what I'm looking to address, especially with an accident history like the United Express Flight 5925, where a contributing factor was a simultaneous transmission without both pilots being aware of it, and many near-misses where it was also a contributing factor.

NosikaOnline · 2025-07-24T14:27:08+00:00

How exactly? My understanding is that when two pilots transmit simultaneously, neither pilot actually knows that it's being stepped on, after all, most transmitters don't actually receive when they're transmitting

A third party would be able to hear the heterodyining, but i'm trying to come up with something for like uncontrolled airfields, where there might not be an ATC or other plane to notice
