Re: Decent HF-VHF indoor antenna

Since you have that receiver, did you ensure that you set the software to use the direct sampling "Q-branch" when you were listening to HF? Also, the supplied antenna that comes with those units is probably next to useless on HF. You really need a longer antenna like a long wire for HF, or you may g...

Re: DIY QFH Antenna troubleshooting

Do you have a multimeter with a continuity checker? That is the easiest way to check for bad coax connections. FM broadcast is very powerful, so even if there is a broken connection it could be powerful enough to capacitively couple through the broken part. NOAA on the other hand is much weaker, so ...

Re: DIY QFH Antenna troubleshooting

Overload is possible, but from your image it doesn't look like your broadcast FM stations are too strong. You can tell if there is overload as the noise floor at 137 MHz will be very high and perhaps with lots of spurious signals arouhd. An LNA is not needed, UNLESS you have a really long run of coa...

Re: win10 issues

The SDR drivers and TV drivers are separate from one another. You can only have one installed at a time.

Some people reported trouble with installing the TV drivers on Win 10, check this thread for the solution http://www.rtl-sdr.com/forum/viewtopic.php?f=1&t=1030.

Re: airspy and spyverter

Can you show a comparison of your results?

I've found that the AS and RSP are very similar on shortwave.

Re: Filter required

I haven't really seen any good low cost broadcast AM band high pass filters before. The best alternative i've seen is this http://www.ebay.com/itm/NEW-Multi-Band-Pass-Filter-HF-6m-Upgraded-version-RTL-SDR-HAM-Transceiver-/282092641588?hash=item41ae081d34:g:Vq0AAOSwPhdVEvuv, but it is quite pricey, e...

Re: win10 issues

Can you give us a little more specifics in what steps you've taken, and what programs you've tried? And any error messages?

Re: DIY QFH Antenna troubleshooting

It's hard to say what could be wrong without physically inspecting your antenna. But does it pick up other frequencies, like broadcast FM? (Even though its tuned for 137 MHz it should still pick up other frequencies). Could you be experiencing overload from other nearby stations? If there is a very ...

Re: Installation Problem with ge-dect2

Never tried gr-dect, but this looks probably like a permissions error. Make sure you are a root user, or use sudo.

Re: airspy and spyverter

Yes as X3nus said, disable the shift. You have the "Use SpyVerter" button already checked, so this will add the required shift automatically (and turn on the bias tee) when you tune to HF.
