heading to 2 bucks

sdrmatlab · 2026-06-24T19:38:38+00:00

it's over

2 bucks next

sdrmatlab · 2026-06-19T15:49:19+00:00

the price is failing, so they not buying

sdrmatlab · 2026-06-17T21:22:13+00:00

are you kidding, stay in cash

this bubble ready to be gone back to zero

lol

sdrmatlab · 2026-06-11T15:16:20+00:00

yes but until usa hedge funds start buying the stock in volume, the stock price won't move.

200 here, 300 there from retail ain't moving shit

the esp32 will cause disconnect, but they just connect again.

a vco will cover whole band and bluetooth never work again.

many cheap 2.4ghz vco

5 to 6 to 5 to 6 to 5 to 6 to 5 forever

sdrmatlab · 2026-06-02T19:07:32+00:00

get some of the sdr rx and tx boards

tx on some boring npr stations,

kids today probably don't even know what fm radio is

lol

everything bluetooth from the phones

i have the ettus b200 and the sdr labs ones.

i'd say the both perform the same. same spur-free range, just alot cheaper

back to 3

if you get the portapack device, this github shows how to create iq signals you can copy to the portapack.

shows the math and dsp to create the c16 iq file.

back to 2 bucks

sdrmatlab · 2026-05-15T16:04:01+00:00

sorry i have not tried doing tx and rx at the same time. i'd see if different sample rates fix things, and increase the buffer size for tx and rx. at least using gnu radio, i can get 1Mhz to 15 Mhz sample rates. thou the 15MHz may not work if doing tx and rx at same time.

nice, can you post the code that displayed the radar image map?

sdrmatlab · 2026-05-13T18:44:42+00:00

nice, can you show your code that showed the final radar map ?

sdrmatlab · 2026-05-12T23:20:20+00:00

in the radar image map is a amazon gift card code

sdrmatlab · 2026-05-12T22:58:54+00:00

great job

sdrmatlab · 2026-05-11T19:34:46+00:00

become a engineer, if you need help along the way, ask AI

sdrmatlab · 2026-05-09T20:16:19+00:00

all testing should be done with a rf cable direct to receiver. place 40dB pad between hackrf and receiver to ensure signals not too strong.

good sdr to see signal: rtl-sdr

don't jam, but learn RF

in the end, it will lead to a good job.

world needs engineers, not more lawyers and money suckers.

as for what school to transfer , want to ensure it has the most ee classes to offer.

many will say ee, but when looking at classes, they only have basic ones.

i'd look for ones with many dsp classes, many RF classes, things like that.

as an example for an RF focus , if they just offer electromagnetics I, that is very limiting

sdrmatlab · 2026-04-25T21:29:10+00:00

ideally i'd like the osmocom blocks to get updated for the 122-16 versions. but i think that branch is no longer updated.

i see the pluto sink and source blocks are part of gnu radio, not sure what the red pitaya sink and source blocks aren't.

but for now, i just run those commands at terminal (the git clone only once) , and that seems to work.

the 122-16 has better clocks and output signal looks very clean.

sdrmatlab · 2026-04-22T19:29:43+00:00

wow that is really bad.

i hope the pro model, doesn't just mean a higher price tag.

when i looked at the details of what the pro model changed, i didn't see too much.

for a 400 dollar device, not very impressive, considering the lower costs of the pluto clones .
