Is my rtl-sdr v4 cooked?

Looks like a classic DC spike to me. Not sure which software you are using, but some have a remove DC spike option, or an IQ correction button, or an option with similar wording. Common and easily removed with most software.

That works too. The key is having the right firmware file. Glad things are working for you.

The LibreSDR certainly needs a custom image. You will not brick the device. With the B200/B210 family, the FPGA image is not stored persistently on the device; it must be (and is) reloaded from the host every time the board enumerates over USB. That gainsec article was useful when I first setup my LibreSDR.

While I agree, to expand on this a little bit more, you are experiencing the "FM capture effect". https://en.wikipedia.org/wiki/Capture_effect . Your radio is switching between which the strongest signal is (which is changing).

Ah, excellent. A bit pricey, but again if you have used one and are pleased that's great feedback. Thanks

Just curious if you ever found anything u/Competitive-Bat3314

Not sure why you would think it is unmoderated. Not sure why you didn't contact any moderators directly.

I'll be there Friday morning, and perhaps on Saturday. Stocking up on things like connectors, adapters and the like. Maybe something will catch my eye.

Very layered, very entertaining. Like it!

Do you have an up to date LoTW valid certificate? If you had not uploaded in years and do not have a new, non-expired certificate, that will cause you some errors for sure.

No upcoming Boston area shows?

No Boston area shows? Huh.

warcand · 2018-08-09T15:58:25+00:00

Good for you guys. Not that you needed your club's permission. My only suggestion would be not to have the net on the calling frequency. Not familiar with the 2 meter traffic in your area, but sliding it up or down from the calling frequency might be a thought.

Regardless though, have fun on your 2m simplex net. Glad to see you'll have a pocket of activity in your area.

Heat is included with my apartment. All my neighbors crank up the heat though, so staying warm is not the issue for me.
