CB SDR radio pe Lenovo TAB2 cu Android
In imaginile de mai sus se poate vedea receptorul SDR de la Matra Systems in functiune de data asta pe o tableta Lenovo TAB2 cu Android. Primele teste arata mici probleme dar in mare este ok. In CB CH22 are frecventa de 27,225MHz si poate fi memorata pt salt direct. Corectia de frecventa in ppm se face usor din meniu.

With this occasion I do the test for my RX - SDR for DX11m ... nice, very nice :-)
A good audio come out from DSP filter (2700Hz), AGC works fine and make the necessary sensitivity for DX, S-meter shows the real uV from antenna and if you prefer the dBm you have it. I must say that I'm surprise by this radio, it has only one small coil inside, 2 or 3 chips and a quartz, the rest is only mathematics form PC via USB connection :-)
By the way, you don't need a fancy PC to do this RX-SDR ... I do the test with my old Pentium 4 at 2GHz /512MB of RAM, running a good old Windows XP SP 3, and with the right software everything is ok.
Pay attention when you install the driver (or .dll file) and the software because you can have problems like this...( photo), only the right combination for your system will work, and set the frequency correction in the soft so called PPM (parts per million).

RX - SDR in CB 11m
Astazi am terminat de instalat echipamentul de RX SDR si conexiunea la antena exterioara dipol pt 11m. Cu o sensibilitate de 0.3uV nu este nevoie de Zetagi P27M, dar l-am lasat inca in circuit cu amplificare 0dB. Nivelul de zgomot este S3...4 in FM (S2 in SSB) iar semnalele se aud bine de la 10...15km departare in 22FM. Pe analizorul de spectru se poate vedea tot ce misca de la 27...28MH :-) dai un clik si pleaca inregistrarea audio digitala, iar semnalul poate fi transmis usor mai departe prin internet. Fltrul DSP lucreaza de minune si la nevoie mai sunt citeva filtre suplimentare. Acum asteptam sa vina propagarea :-) .
