Hi,

I have been running my X40 with the transverter for about a week on a Windows 7 computer. Last week I connected the combination to my I5 laptop with USB3.0 port. This is running Windows 10 Beta versrion. When installing the Windows software from the Nuand website it offers to update the firmware, which succeeded.

Playing around with the X40 and the SDR Console (2.3 Beta 1990) it does work OK from 300 MHz and up. On HF however, there is no reception. Except for a small part between around 35 and 60 MHz.

I also tried the bladeRF-CLI (version 1.1.2 ) with set frequency, but setting frequencies below 300 MHz result in strange responses. Setting it to 101.5M gave as result that it was set to 237 MHz (give or take a little, do not remember it completely)

I switched back the BladeRF to the Win7 computer, and on that computer also the frequencies below 300 MHz only do HF on 35 - 60 MHz and on the other HF frequencies there is no reception.

Currently I have no clue how to solve this. Neither do I know at the moment how to check which firmware was flashed yesterday and how to revert to the previous version.

Does anyone have any idea ?

Thanks in advance,

Hi, at first, thanks for your fast reply !

here's some info output below is from my Win7 computer where it had been running last week.

To make things clear: I was not trying to receive or transmit within the 35 - 60 MHz range. I noticed that my BladeRF did not receive anything on the transverter, not even a local radio broadcast on 87.6 MHz, then I tuned down, and between 60 down to 35 I see noise and some pagers around 39 MHz but below 35 MHz all signals disappear again. So, no 10 meter, 15 meter, 20 meter and so on. I have to admit that I also switched the antenna from the logper to a QFH antenna, but the FM broadcast station transmits 5kW at 2 km distance and even that does not come through.

When I first received the unit I connected the RX to the transverter and the antenna to the transverter antenna connection and had SDRconsole running without problem, automatically switching the transverter when tuning. I have no (custom, homebuild) filters attached and I use the default LPF settings.

This all worked quite well, taking a learning curve for the gain and bandpassfilter settings, but I could receive AM from 1008 kHz up to Wifi @ 2400MHz

I did not copy the bladeRF.dll to the SDR-console folder at first, I did now, but at the moment I cannot restart SDR console completely because one instance is recording from a dongle. I restarted the instance with the BladeRF however, but the new dll does not improve my situation.

I hope my comments make things more clear, if not, I'll try to explain better.

Kind regards,

Hi Jynik,

all works now.

I have made an error when I connected the bladeRF to the Windows10 laptop to do some rx and re- tx experiments. To be able to TX I had to remove the SMA patch cable (XB-200 RXFILT port connected to the RXFILT_ANT port) and used that one for the TX connection for the transverter. Still received signals at 400 MHz with LPF mode bypass so I assumed that LPF mode bypass was a (RF relay) switch wich bypassed the bandpass so I did not have to attach that patch cable.

Now, I attached another SMA patch cable XB-200 RXFILT port to the RXFILT_ANT port and I do receive all signals now.

For the TX experiments I attached the antenna directly to the TXANT on the XB-200, Am I right to say now that I also need the SMA patch cable for the TXFILT to the TXFILT_ant port and if this is not attached I am transmitting without antenna ?

Thanks again for your reply,

Ben
