$20 RTL-SDR v3 edition

On August 16th 2016 released the brand new v3 edition of their very well known RTL based SDR dongle.The v3 edition has added a lot of new features but one feature that stands out is the ability to receive HF.

Without getting overly technical this new model will allow you to listen to HF from 500 kHz right on up to 24 MHz by making a selection of the Q branch within any supported frontend.

The previous editions also allowed you to listen to HF but you needed to make some modifications to the PCB.

Now If you want to listen to DX on 80m, 40m & 20m... No problem. Feel like listening to world news as it happens and unfiltered...No problem. How about listening to clandestine or Military operations...No problem. Listening to HF communication is just one feature that was added. You can still receive transmissions from 30 MHz up to about 1.8 GHz.

What I mentioned above is just some of the additions added to the v3. This dongle packs a lot of punch for $20.00. Everyone says that the RTL-SDR'S "Allows you to get your feet wet in the world of SDR'S" Which is true but with this new v3 you get so much more for such a small investment. $20.00 is nothing compared to some of the prices of HF SDR'S. Don't expect the v3 to match up head to head with a $700 SDR with a 16bit ADC. One thing I will say is that the new v3 edition can hold it's own and actually quite well.

This one is without a doubt staying in my collection. has a great product. I can't say enough good things about this company. They took a run of the mill 820t2 and made it into something worth using and enjoyable. With the right software and antenna you have a complete coverage SDR for 20.00

 Apologies in advance for the quality of the video. I'm still waiting for my camera to come in. I shot this with my cell phone in one take unedited. See you all on the next post. Before you watch my video I highly recommend you bookmark the following sites

 I just got the radio about 2 hours ago and already I'm super impressed with it. I will be doing a write up in the upcoming days. Right off the bat the RX audio is loud and clear. Did a quick test on the Alpine repeater out in New Jersey and was told I sounded fine. Honestly for $20.00 how can you go wrong. Much more to come on this model. In case you can't wait

HDSDR Master frequency list.

About a year ago I started to compile a master HDSDR frequency list of common HF frequencies for personal use. My list has about 1000 entries and is updated often.

 I decided to make this list available to all SDRplay RSP users free of charge. It makes tuning common broadcasts within HDSDR so much easier.

If your interested in the list or would like to learn more about the SDRplay RSP SDR I invite you to join us is in our SDRplay RSP Facebook group. We have over 3,400 members and it's going daily.

BTECH uv-5001 2nd gen needs fans part 2

A few months ago I posted that the UV-5001 needed some sort of cooling and after numerous complaints BTECH released the v3 aka gen3 version of the UV-5001 which included a very small and loud internal fan. The community seemed happy and loved that BTECH addressed the issues but this newer model still had issues.

My friend John who is no stranger to the world of Chinese import radios stepped up to the plate and posted a fantastic UV-5001 gen 3 internal fan mod. John's site is loaded with many how-to's & new release reviews.

The original 12v fans I installed died and to be honest I wanted to ditch this radio and go with a brand new BTECH UV-50X3 but for some reason I can't do it. Granted my radio does have some quirks and a design flaw but I just chouldent do it... Despite all the problems it does pack some serious punch.

The fan I decided to go with is a single 12v Artic cooling f8 80mm priced at $6.00 shipped. I have it in the same configuration as the last fan. Fresh air is blowing down onto the rear part of the heat-sink. I tried doing this in the reverse (fan pulling hot air off the heat-sink) and the radio still overheated. The Artic f8 is moving a greater volume of air vs the dual fans I had. The radio used to get a slightly warm to the touch with 2 fans but now using a single fan the heat-sink is not even warm and the radio works as it should.

This does leave plenty of room to come up with your own DIY Arduino fan controller so the fan is not running all the time. The possibilities are up to you and that is what this hobby is all about.
