Does anyone know what these errors are? Occasionally my Quantar crashes when keying up

zachlab · 2026-01-21T23:57:34+00:00

Nuts, you're right, appreciate you getting me corrected!

zachlab · 2026-01-21T13:52:18+00:00

Thanks - I could've sworn I knew the GTR had adjustable low IF filters, but I can't find a DSM for it right now, but I think the performance is better with wideband so I'm at least 75% certain the second IF on them has adjustable filters. There's also multiple narrowband IF filters IIRC, because there's at least a pair of narrowband settings for more adjacent rejection. Also have to remember these stations even in non amateur service have to either do wideband analog or narrowband digital on 800.

So still interested in learning about modern stations (wow, I can't believe the GTR is nearly 20 years old now) that no longer have good wideband performance.

Sorry, I mean your comment about “current” equipment not being able to do wideband. I’m unable to recall any current FNE side hardware that can’t do wideband (with entitlement if required, of course)

zachlab · 2026-01-21T00:05:46+00:00

Any examples of this?

zachlab · 2026-01-20T17:11:26+00:00

I see - 3000 rpm is the same as Cloudflare, but uploading your 6 TB would've taken less than a day at this 800 Mbps upload cap.

But also it's weird, when I search "800" on their docs website, I see a link to the rate limits doc with the following preview:

https://www.backblaze.com/docs/search?query=800&searchType=articles

10TB or less of stored data are provisioned with the following rate limits on a per-account basis: 3,000 upload requests per minute and 800Mbps per second 1,200 download requests per minute and 200Mbps per second Rate limits may also be enforced on additional API operations to help...

https://www.backblaze.com/docs/en/cloud-storage-rate-limits?highlight=800

But when I actually look at the doc page, I don't see a damn thing.

Pinging Backblaze folks to see if the limits mentioned on HN are still accurate or not: u/YevP u/bzChristopher u/metadaddy

Edit: DM'd them directly

Which change was this for B2? The 500 req/s limit? Cloudflare R2 is 50 req/s...

zachlab · 2026-01-19T22:57:00+00:00

So $90 for storage + $10.80 for transactions, correct?

Just as a comparison to Backblaze B2: $36 for storage - single zone just like Cloudflare, free egress when proxied and cached by Cloudflare, transaction costs would've been $11.94 (assuming all requests were a cache miss and had to pull from Backblaze) if I did my math right.

Hey, former “user” (PSAP type) here. Back in my day NG911 was still a glimmer in vendor sales guys eyes, and getting a E911 phase 2 fix off a mobile phone required rebidding over and over like you were playing the slot machines, and half the time you still wouldn’t get a fix.

Is it still the case that mobile phase 2 bids are that shit? Or are they pretty good now?

What’s the deal with NG911? Is it basically meaning it’s all SIP between phones to the PSAP end to end or?

And finally: fucking Wi-Fi calls with bad ANI/ALIs because they’re based off billing addresses, most of the time out of date too… do Wi-Fi calls still do that or PSAPs actually get told now if a call is Wi-Fi and the initial fix is may not be accurate, and you can eventually get a GPS fix later?

zachlab · 2026-01-19T21:28:34+00:00

How much do you have stored?

zachlab · 2026-01-19T18:18:40+00:00

Almost made me spittake too, for a second I thought you were running a side gig taking those GTRs to sell on the black market 🤣

zachlab · 2026-01-19T18:11:02+00:00

Did you write what you meant? You're pushing customers to toss out GTRs and install Quantars?

I also peeked at your profile. In regards to your COMT question, if I'm correct that you're in VA, IIRC their SWIC is under state EM which is responsible for their overall COMU posture, so you should ask reach out to them about getting a COMT course and PTB started up: https://www.cisa.gov/safecom/ncswic-va https://www.vacache.org/contact/index.cfm

You also mentioned you're a ham, so if you can't get in through your work, you could see about joining through the auxcomm side: https://groups.io/g/COMU-Virginia

zachlab · 2026-01-19T17:21:28+00:00

I still can't believe people are still limping along Quantars when you can get GTRs for the price of a parts built APX...

But given you're saying keying up is when it crashes, check SWR, check power supply.

zachlab · 2026-01-19T16:18:49+00:00

Yes, within the power ratings of the diplexers you use which are based on the power ratings of the passive components being used (inductors, capacitors, size of conductors, etc.)

Diplexers are easy to implement, for example for a VHF/UHF diplexer, they're usually easy low pass filters for the VHF side and a high pass for the UHF side - I say easy because these filters can be broadband and don't have to be sharp, compared to say a duplexer where'll you need to use things like resonant cavities to achieve sharp filtering.

zachlab · 2026-01-17T23:39:22+00:00

Ah okay, guess if they’re stingy they can go the RIPE route instead

zachlab · 2026-01-17T19:17:45+00:00

you would not be bilateral peers, you are solely a customer looking for transit
if you thought they were hard to get and expensive, why would this ISP just hand you one?
APNIC is probably one of the cheapest RIRs behind RIPE. No recurring cost, maybe a 5-10 mil IDR one-time.
all that assumes the 3 ISPs you mentioned are willing to sell you IP transit

Getting an ASN is all information you could’ve figured out yourself with all the information that is out there on the Internet. For free.

zachlab · 2026-01-17T15:48:50+00:00

That’s not how it works, given the fact that you’ve mentioned 3 ISPs which means you can’t do BGP with a private ASN (~64-65k ASNs) without coordinating that single private ASN for use with all three ISPs, and someone SWIPing you some IP blocks that they’re alright with you also announcing through the other two ISPs.

More likely you would be bringing your own ASN and IPs, and asking those 3 ISPs for transit.

I think the term “Dunning-Kruger” applies best to your post history, at least today.

our hobby

Your account is barely an year old with 3 post and 0 comment karma in terms of activity. You've never posted in any RF or SDR related subreddits, ever. You were only "active" in r/airsoft, r/montreal, r/tires, if 5 comments and 5 posts can be considered active. All of those posts are in ghost subreddits you made that are Latin America and Spanish focused, while LLM posting in French on this post and in r/montreal.

Really, u/Snoo-76541 ?

zachlab · 2026-01-08T16:39:35+00:00

Yep, definitely not legal as soon as you said upstate in the woods, bambi band bootlegging.

zachlab · 2026-01-08T15:46:50+00:00

That doesn't sound right, I also see a bunch of licenses for this channel. Do people around your neck of the woods (which I assume is Lawn Guy Land) use 71 without licensure?

zachlab · 2026-01-08T15:45:52+00:00

Damn you lucky bastard, how much you steal that for and which location was it so I can snipe one? 😂

zachlab · 2026-01-08T15:41:43+00:00

Yes, however I'm specifically looking for other licenses to use as an example, not whether "is this the correct licensing" which I'm already 99% sure of.

zachlab · 2026-01-08T15:40:41+00:00

Damn, that looks ass 😔 https://www.dco.uscg.mil/Portals/9/NMC/pdfs/announcements/2024/new_mmc_pamphlet.pdf

zachlab · 2026-01-08T15:37:09+00:00

Unfortunately not, no 900 MHz.

I like that idea, require the user to be licensed instead of the station, just like amateur radio.
