Re: Where do you buy these tiny aluminum enclosures?

Hello! Thanks, I also received them recently, but I noticed a few differences. The current enclosures have a shiny surface; previous batch had a matte finish They're unbranded (no logo printed on the surface) There are only 2 screw holes available on the side panels compared to 4 in the previous bat...

Re: Unknown high pitch continues beep with data bursts

I've seen this type of signal too. It just beeps for most of the time and occasionally there are some data bursts on it. Mine was near 434 MHz though (south Europe). No idea what it is for.

Re: Splatter, noise or ? 450.675 MHz

Probably not. The restaurant pagers seem to ping randomly and are not associated with any periodic pattern. This makes sense because customers will have their food prepared at different time intervals (delays). Finally you can probably correlate the frequency of pings with the number of customers in...

Re: Splatter, noise or ? 450.675 MHz

That looks like some variant of 4FSK. Did you pick up this signal near a restaurant perhaps? I think some pagers use this exact frequency.

Re: 433mhz waveform. FSK? GFSK? GMSK?

Looks like 2FSK to me. The two peaks are the two alternating frequencies.

Re: Where do you buy these tiny aluminum enclosures?

That antenna connector might be a bit big IMHO for the v3 enclosure. Perhaps replacing it with a SMA connector will do the trick. You will need some soldering skills though and be sure to order an appropriate SMA connector that will fit in the void. As a bonus you won't have to modify the side panel...

Re: Where do you buy these tiny aluminum enclosures?

Hey, rtlsdrblog!

I noticed the enclosures are now on sale again in the shop. Planning to buy some. Guessing from the picture, am I correct to assume that each piece will ship with the main chassis, one USB side panel and *two* SMA panels?

Thanks!

Re: Discone antenna

I don't see why not. You will need an appropriate adapter as the antenna has a type-N connector while the rtl-sdr has SMA. If you plan to use the antenna on a roof with a longer coax cable, consider adding a LNA in between the long cable and the antenna.

Re: Where do you buy these tiny aluminum enclosures?

rtlsdrblog: Actually now that you mention it I would also be interested in the rtl-sdr v3 enclosures, provided that you can supply multiple SMA side panels and screws (either SMA or full; the ones with USB holes are useless). I have already bought some of them from you in the past, and I've been ab...
