I setting up an experimental Spy SDR Server with my RTL-SDR dongle on the following address during this weekend:
sdr://sarloserver.dlinkddns.com:5555
Download the latest SDR# Software and choose Spy Server Network and enter the address above.
Due the strong local stations you need to set the Gain to 3 but on the bottom of FM band you can increase it to 12!
Note, this is a very very experimental stuff.
Antenna: Vertical dipole on the roof, 35m high with low noise AMP.
QTH: Székesfehérvár, Hungary
Range: 30 - 108 MHz

Re: SDR Spy Server test Hungary
It's working well AMDXHUN - I just wish the band was as clear here in London as it is there in Székesfehérvár, Hungary.
I had a quick tune around on Band II - quite a few stations but I only got RDS on:
Alpha Radio-88.9
Music FM-89.5
Maria Radio-90.0
Radio 1-90.6
Kossuth-92.3
Strong sig on-93.9 (no RDS)
Radio 1-94.5
Katradio-96.1
Taska Radio-97.5
Vorosmarty Radio-99.2
Retro-100.5
Karc FM-106.6
Thanks for putting that up online, are they all legitimate stations or were some of them pirates as some stations appeared to be a bit off frequency.

93.9 and 94.8 is Petőfi Rádió, but with low RDS level.
There is no pirate stations at this time, the "off frequency" ones are IMD in the stick.
The only pirate station is Sound 93.3 but only a few days per year.

Re: SDR Spy Server test Hungary
Hello,
I tested your server last night and it works well! I took the opportunity to update some information on FMList.
Thank you for sharing your receiver. I would like to do the same but my upload speed does not permit it unfortunately. Optical fiber is coming soon here so maybe it's just a matter of months!
By the way, we're not obligated to download the latest SDR# version to use your server. I'm using the v.1.0.0.1637 and it works!

Re: SDR Spy Server test Hungary
The SDR is on-line again today

You must decrease the gain to 4-3 when tuning to a strong local station.

Hello there,
Tested out your server and it works pretty good. Can you tell me what type of dongle you use and if there are any filters?

Re: SDR Spy Server test Hungary
Simple commercial DVB-T Dongle with Rafael R820T chip.
The antenna is one vertial dipole attached to the Elevator-house on the roof (~35m high) with Low-Noise AMP lead by ~ 40m of Coax. The coax is splitted to 4:
-My Kenwood hi-fi (For regular listening in the bedroom)
-My Sony tuner (For DX)
-To the SDR (For DX and monitor)
-To the old Videoton tuner in the living-room. (For regular listening)
The gain is enough to feed the 40m coax and the 4 devices.
The filter is only one "Coax-Choke" before the Dongle
