Good plan :-)

Hi Stu, As an experiment would you be able to compare the MLA-30 using the loop and then replace it with 2 x 1m long wires as a short active dipole ? This would give an indication of the amplifier input impedance. Taking some screen grabs of the …

> >how is the TC2M with respect to local noise pickup? > If you decouple the feed line they are not too bad. It's a pity the antennas are currently dismantled, otherwise you could have compared them yourself. But generally speaking the TC…

Hi Stu, This is an interesting idea, but it looks a bit cumbersome (if I understand what you are proposing correctly). I wonder if another method would be to allow users to navigate by 'stepping' through the displayed DX tags. If you then used t…

Hi Stu, Seems OK mid frequency range, above about 20MHz the noise floor is a bit high and below about 3MHz it's performance drops off a bit. It will be interesting to see how will it performs once you have played with it a bit more to optimise the…

Hi Glen, You should be able to make the whole structure active and a lot slimmer. The problem with a lot of E-Probe antennas is that they tend to use a very small plate antenna, which only has a capacitance of a few pF. If you use a fat cylinder a…

I just checked the supplied drivers disk just in case, but it only contains Windows versions.

Unfortunately no, it's the same as before.

OK it's removed, but what exactly do you want me to try again ?

Hi Andy, I can confirm it's a rtl8192eu chipset. I opened one of the dongles up earlier on, but I wouldn't recommend doing this. Perhaps catch up later, but don't worry as I'm out and about for the next couple of days anyway. Thanks, Martin

Just checked the one working on my Windows 7 machine. Hardware Rev E1 Firmware 5.10 Windows driver version 1030.25.701.2017

Yes that's probably it.

Installed rfkill It's not returning anything

Hi Glen, I think we are reading from the same page, using a WiFi/USB dongle to remove the need for an Ethernet cable is definitely a good idea. However, even if we effectively screen the KiWi, and keep it's noises inside the box, there is still ot…

Hi Glen, If you remember the diagram from this thread http://forum.kiwisdr.com/discussion/comment/5531 I think the problem is associated with the center tap on the Ethernet termination transformers. They act a bit like voltage Baluns and so are su…

Hi Glen, I think for me the main issue is that the interconnecting cables are not all bonded to the case at the point of entry with low impedance connections. So RF currents will flow via separate routes across the PCB's and find various ways of i…

Which version did you use ? N150 Mbps ?

It's easy enough to minimise any risk by saving an image to SD card before you start making any changes. Then you have a 'get out of jail card' in case anything goes seriously wrong. I've always done this as my Linux skills are minimal, and it's …
