Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who shares the following video review of the new RTL-SDR dongle on the shortwave and mediumwave bands.
This is daytime reception comparison. Nighttime could be a different picture. [The RTL-SDR dongle] tunes and frequency is 100% on spot.
Using SDR Sharp you have several AGC settings to play with and find the best combination. The best setting seems to vary with band and signal strength.
The [SDR receiver] comes with a short (20 cm) and long (120cm) telescopic antennas. Neither one is usable for HF or Medium wave.
When ordering the radio you have to get a USB extension cord for the dongle. When plugged in directly into a laptop and then antenna coax it can become bulky. You also will most likely need an SMA adapter to BNC and SO 238.
I hope this helps.

Many thanks for sharing your video, Ivan! For a $25 SDR, I’m pretty impressed so far! I’m also very curious how it will hold up to stronger nighttime signals and, especially, adjacent signal interference. I imagine it may be prone to overloading as well. Please keep us posted!
Have any other Post readers tested the new RTL-SDR dongle on HF? If so, please comment!
Just got my v3 dongle today and connected it to my HF antenna and was very surprised at the reception, see my video on this at https://youtu.be/YSLfUFKqOGI
With Shortwave SDRs (the receiver dongle) now costing less than $20 the time has come for us to set up a global group of receivers that we can all log into at will! Have a look at SDR.hu – here you can put your SDR dongle on line and share it with anyone and they have full control of the receiver just as if it was in their own shack. Imagine receivers scatted around the world – South America, Tropical Asia, Africa! The cost is now virtualy nothing, all that is needed is the dongle, antenna (doesnt have to be anything special – even a long wire or whip) and a small low cost CPU (Raspberry Pie for example). Anyone else interested in this dream? Lets get togeather, get some receivers setup and then talk about our experience in a kick-ass presentation at the 2017 SWL WinterFest in PA!
Also… I am very soon to receive my KiwiSDR matched to a BeagleBone CPU. It will be online at SDR.hu and four remote listeners will be able to tune the full shortwave bands independently, its like my own Twente setup! Heaps of others are getting receivers online in the next few months with KiwiSDRs, this is going to be totally amazing!
Mark for the cost of a v3 and a pi2 and the possibilities your idea is great.
