Lucky or did I miss something

Hi all

1st--
As mentions on the manual of the FUNcube Dongle Pro+.
Two concurrently running applications are required to operate the FUNcube Dongle
Pro+
FCHid
SDRSharp.

I did the setup with both programs and everything went nicely .I was succeeded
to receive many satellites beacon and transponder as well as HF and broadcasting
stations.

Now I run the dongle without FCHid software and the result is great too. I can
tune to any frequency with SDRsharp only.

Steps I follow
1- typing the frequency that I need at central frequency box.
2-Then click on the frequency box above.
Frequency value at the frequency box and on tuning display will change to the
same value of typed frequency.
(For sure at display it will be the central frequency)

2nd--
I used the frequency correction (configure window) of SDRsharp With aid of my
Racal 8091 frequency synthesizer my Rigs and many broadcasting frequencies I
found the best (ppm) calibration at 0:0 With this ppm value every signal
received was 100% correct with its transmitting frequency.

It seems to me this Dongle is unique :)
Very easy setup
Insert the dongle to the USB and do the rest via SDRsharp.
I well enjoy it now.

TinySDR

TinySDR by LY1GP It's a very simple direct conversion receiver consisting of nothing more than three parts:

1) Simple LC band pass filter;
2) Mixer; and
3) VFO.

No AF amplifier stage, it just feeds the output direct to the sound card MIC input and leaves it to do the amplification etc. Oh, and the VFO is coupled into the mixer via a phase transformer thereby providing two different phases - one at 0 degrees and one at 90 degrees - and thereby making the output that of (I believe) an IQ SDR receiver.
My 1st version work very nice ,It need more work at VFO.
tnx VK1IS for the webblog .

Nice comment Paul GM4ULS , Thank you OM .

Yesterday I was in a three-way QSO on 10m AM with two American operators. The technologies in use were very diverse. One of the stateside hams was an old Johnson Valiant transmitter, the other was using a Flex 5000A software defined set-up, and I was using a little single-band Chinese rig (Anytone AT5555). It's wonderful how such different technologies can be put to the same use.

Really it is joyful to listen to DX station with some discreet components and your PC.

The Crystal oscillator is not suitable for good band coverage.
Next step I will add a VFO. The one I've built for 20m was unstable suffering too much frequency drift!
