If you would like to submit something that relates to cheap SDR (a project, blog post, something interesting you have found), please email us at [email protected].
We will look at your submission and if we think it is a good fit for our blog make a summary post about it, making sure to link and credit your original source. If you don't have your own website or blog, don't worry, just write about your project in an email and we will host any images or documents related to your project for you. Usually we will get to your submission within a few days.
Please note that we will not accept payments or incentives in return for any type of post except for product samples for an honest review. If you are interested in writing a non-commercial guest post for us, please also contact us on the above email address.
If you have a general question about RTL-SDRs or SDRs we ask you to please ask in our forums.
If you need troubleshooting support please first ensure that you have been through our Quickstart guide and the troubleshooting section on it, as well as our V3 users guide. Common questions like how to use the HF mode and how to activate the bias tee 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. 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. If we don't respond within 3 business days then the mail may have gone to our spam folder. Please try to email again using different keywords. We do check our spam filter once a week just in case, but some messages could still be missed.
