SDRplay RSPduo End User Review

Introduction
After using the new RSPduo for a couple of months, I can say yet again that SDRPlay has produced another excellent product in their inexpensive line of wide range SDR products. After the original SDRplay RSP1 was introduced SRplay continued to enhance and improve the platform by releasing new models with improved and new features. However the new SDRPlay RSP units such as the RSP2, RSP2pro, and RSP1A were evolutionary products. Recently SDRplay introduced a revolutionary SDR product with the release of the RSPduo. What makes the RSPduo unique is that unlike previous RSPs, the RSPduo use two separate 1kHZ and 2GHz 14 bit tuners each having up to 10MHz of bandwidth. Of course the best part is that SDRPlay managed to bring the RSPduo to market with a list price of only $279 is pretty amazing. Ok. lets put that into perspective. Right now their only two SDR transceivers  on the market that feature dual independent receivers. They are the Icom  IC 7610 (street $3200),  Anan 7000DLE ($2995),  Anan 8000DLE ($3595) and the Flex 6600 (starting at $3999). Ok to be fair, these radios are 100 to 200W amateur radio transceivers, but if you want a SDR receiver …

Flex Radio 6400M Video Quicklook

In the spring of 2017 Flex Radio announced an upgraded version of their 6000 line of SDR based transceivers. These models were labeled the 6400,6600,6400M, and the 6600M. In a nutshell, the 6400 series is an upgrade of the dual slice receiver 6300 and the 6600 is an upgrade of the four slice receiver 6500. The M series adds an 8 inch color touch screen display plus knobs and buttons for “no computer needed” operation. The chassis has gotten larger on the new 6000 series also. With exception of the size change and the builtin displays most of the changes are internal such as better filtering. The new 6000 series also come with the latest version SmartSDR which features an improved remote over internet component called SmartLink. Flex also managed to keep prices down on the new 6000 series. The 6400 starts at $1999 without the optional built in antenna tuner. This makes the 6400 very competitive with most midlevel 100 watt legacy transceivers currently on the market. This makes the 6400 a good solid choice for those who would like to upgrade their equipment to the higher performance of SDR technology on a budget. The 6400M for $2999 adds …

New Forum for Ham Radio Science

As of today, HRS has decommissioned the old forum. We were just getting too many spammers. The new forum will allow us a better opportunity to help reduce some of the spam. Unfortunately, we were not able to move the user database or the old posts to the new forum. If you were a member of the old forum, you will need to sign up again. The old forum will be available for a little while longer, but we will eventually remove it. Let me encourage you to try to post your comments and questions in the forum. I have noticed that the comment sections of some of the articles are getting a little unwieldy. You will probably stand a better chance of getting an answer to your questions, if you post them in the forum.

Thanks for your patience!
