Product Support

If you have a general question about RTL-SDRs or SDRs we ask you to please ask in our forums.

If you need technical support please first ensure that you have been through our Quickstart guide and troubleshooting section on it, as well as our V3 users guide. Common questions like how to use the HF mode are explained on the V3 users guide. 

If you have a question about shipping of an item please first read the shipping policy on our store and see if it answers your question. The shipping information is just under our product listings. If it is a request for tracking details please first check your old/deleted/spam mails for the tracking email which is provided by PayPal. You should have two mails from PayPal. The first showing ‘in process’, and the second 1-2 working days after showing the tracking details.

If you suspect a lost postal item please contact your local postal agency first and inquire there. Usually they have more information than we have. If they confirm it as lost or not received after a long time then please let us know and we can open an investigation on this side as well. Usually we must wait at least 6 weeks from the date posted before we can open a lost parcel investigation.

For everything else such as confirmed lost postal items, warranty claims and support inquiries that aren’t covered by the quickstart or troubleshooting guide then please contact us at [email protected]. We aim to always reply within 1-2 business days.

    A friend has your receiver kit with the collapsible antennas and base. His kit does not have the dipole but rather a much longer collapsible whip that is threaded at the base so that screws ONTO the mount. I have a need for a long collapsible whip (over 1m) and would like to purchase that antenna or kit if you have them in stock.

    Really looking forward to getting my hands on a v3 (just recently learned SDR exists!!). Once received and an SDR s/w loaded on my machine, which addition software could I use to decode CW/RTTY/SSTV/WEFAX from an incoming signal without having to use an external wire from speaker output to mic?

    • admin

      Welcome to the world of SDR! You can use any decoding software with an audio piping program like Virtual Audio Cable or VB Cable. No need for external cables.

      Look up decoding software like CWGet, SeaTTY, fldigi, multiPSK, MMSSTV for those modes.

        Thank you. I am aware of them all but run into a problem with my Lenovo T450s laptop. It appears they took out the internal speaker-mic bridge and its not an option from the Control Panel. I installed the Virtual Audio Cable as well and that hasn’t worked either. I might have to build an external bridge myself to connect speaker/mic, with my earphones in parallel, but I’d rather not. Any suggestions would be greatly appreciated.

    2nd week in March and Amazon RTL-SDR bundle still not available. How much longer or are they available sooner through your web store?

      Sorry it’s just been delay after delay with this shipment to the US. But it’s on the final leg now. Assuming no other screwups from the shippers it should be delivered to Amazon this week, and then then Amazon usually takes a few days to process the parcels and put them in the shelves. Probably 1 more week until it’s ready to be purchased again.

      Web store ships from China and takes about 2-3 weeks for delivery.

        Just saw they will become available on Amazon on March 18th. Already placed an order. Suspect you’ll be out of inventory pretty soon. 🙂
