Given the choice of the two, I think I'd zig-zag the length, rather than double it back. Doubling back is liable to cause cancellations and reduction of signal strength at some frequencies. HST, for

Ah, that sounds like Microsoft - making the world safe for malware. {+_+}

Hello, I've had to relocate my 133' 80-6m dipole to the attic after coming down outside in a winter storm. The run of attic along the roof peak is 64' inside. I've extended the dipole end to end for

I'd measure the pptc first and if it is open then pop the unit in a sealed airtight bag and put in the freezer for a couple of days - then remove it and allow 24 hours for it to return naturally to

The NESDR SMArTee has a 4.3V bias-t. I've just spotted on the Spyverter specs that volatage requirement is as follows: Bias-tee voltage: 4.2v to 5.5vI was only worried as none of the NooElec devices

The Spyverter is compatible with pretty much everything. If the device has a it's own 5v bias-t, then great, if no, then there's an external micro-usb for power.

Hi, Does anyone know if the Spyverter is compatible with NooElec SDR's? The specific combination I've got in mind is to use the Spyverter with NESDR SMArTee. Thanks in advance!

Dear Developers Long ago we requested the feature for data logging out of AstroSpy and we received the answer, that all the development power was focused on the release of the HF+. Because the HF+ is

Decoding is also OK when running a Spyserver ...

Because a pic probably explains better ...

Hi there ! Yesterday, after W10 April update (v1803), I noticed that both RDS spy (via MPX Output plugin) and DSD+ did not work. Here is the explanation a kind guy sent me : in Win 10 1803 Build

There is a PPTC for the Bias-T ( https://en.wikipedia.org/wiki/Resettable_fuse ) on the Airspy NOS R0 and Airspy NOS R2. I think it is marked as FB2 on the PCB, but I could be wrong (see bottom left

Hi all, Has anybody ever had the bias-T LDO device (LP5907MFX-4.5/NOPB) in an Airspy R2 meet it's maker and replace it ? My own one has blown somehow and I need to replace it. I can do this myself but

As I said in my previous message: DO NOT change anything if you are not involved in designing RF front ends and know exactly what you are doing. You will get better results if you avoid falling in the
