NaP3 (Panadapter) SDR Software (F5VNB)


(For SDR-FORUM / Questions , Answers or Remarks ... scroll down on this page.)


NaP3-v.2.6.6.     NaP3-v.2.8.8.     NaP3-v.3.0.0.     NaP3-v.3.1.0.

NaP3-v.4.0.0. RC1     NaP3-v.4.0.0. RC3

Please NOTE : The version of NaP3-v.4.0.0 RC3 has a bug and so not on all systems it will run ok without a crash and as result You get a frozen screen . I don`t know who could in future time solve this bug . See this link :          (             Also it is strongly recommended if You like to install or change between the different versions that You at first NOT ONLY let run the programs uninstall-routine ... because some entries in the computer-registry will not deleted and the install process of the other version will not run and also the program will not start ! Also it is recommended it should be done a database-reset in the older / earlier version of NaP3-program. For get a really clean registry and clean new installation without old entries from earlier versions of NaP3 You must clean the "brain remember" of the computer manually by using this software here :     Revo - Uninstaller 1.95 .

As far as I know , is the SDR program NaP3 OPEN SOURCE software. Unfortunately , I am not a specialist for software development and I do not know from where the source code is to get of the program for further developments or possible bug corrections - maybe could make from radio amateurs , who deal with software development as hobby in their free-time .

The author claims in the About box that NaP3 is an open source software, but I can't find the source files anywhere. Any info on this matter, or how to take contact with the author ?

Localhost connection problem ... ?

Jim AD1C 10.06.2015
I am having a problem using the Spots function in NaP3. I'm using 4.0
RC2 (I think). It's the version I downloaded from the LP-PAN 2 web

I can connect to localhost:7300. I can not connect to,
i.e. using numerical address for localhost. Other numerical addresses
on my LAN do not work either (I run cluster software on a different PC
from the one running NaP3). My LAN is 192.168.0.x

I was able to connect an Italian cluster node that uses a numerical IP
address, without any problems.

Is this a known bug? Is there a fix?

Thanks & 73 - Jim AD1C

Is there a driver where we can use a RTL2832 USB adapter with NaP3 ?
I currently use a ExIO_RTL2823.DLL and can use the dongle with SDRSharp and SDRConsole...
