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.

The VHF Pre-Amp - Transistor was BF981
On services since 10 years
No TR/RX relay . peaked to 137 MHz for receiving the weather satellite .

CI-V interface built on perforated PCB - with external DC power supply
PC sound card interfacing
later 1:1 isolation transformers were added
VHF/UHF on single boom
You Can't Resist !!
At a cold winter night you can't resist listening to a DX station with a great signal.
Since I built the DC Rx last month I've shut down all other fancy black.boxes.
The Rx still sitting on the workbench in parts connected with jumpers.
The antenna is just a loosey goosey long wire .
Why should I do this? Because it's fun.
