Flex Radio 6400M Video Quicklook

March 23, 2018

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 …

RSP1A Overview and listening tests. Listening tests were conducted in real-time. Each radio was connected to the same antenna with a splitter. There is probably some amount of insertion loss, so your results may vary.…

New Software Support for SDRPlay RSP2

January 10, 2017

If you are the owner of the fantastic new RSP2, you now have a few more options as to what SDR software you can use it with. Besides the SDRUno software that was developed for direct support of the SDRPlay RSP series, SDR Console Version 3 developed by Simon Brown will now support the RSP2. SDR. SDR Console is very nice SDR program with a clean user interface and loaded with features. Also HDSDR now supports the RSP2. HDSDR has been around a long time and offers a simpler approach to using SDR radios. The user interface is very straightforward and friendly to beginners as well as experienced users who appreciate a fast and easy interface to a SDR radio. If you download the HDSDR software from SDRPlay’s website, it comes with the EXTIO files you need in the installer. So it’s pretty much plug and play. With a great choice of SDR packages the SDRPlay RSP series of SDR radios continue to be one of the most flexible SDR radios available today. Not to mention a great value.…

Rumlog 7300 Scope Feature Demo

December 19, 2016

If you have an Apple Mac and an Icom IC-7300, you may want to take a look at DL2RUM’s Rumlog NG software. Aside from being a very nice logging software package it offers a resize-able spectrum / waterfall scope that can fill your entire PC screen if you wish. This is a nice improvement over Icom’s RSBA-1 software that limits the display of the spectrum / waterfall when connected to an Icom IC-7300 to a fairly small area. The scope drawing performance is pretty similar to RSBA-1 due to the rather slow serial communication rate of 115200 baud. To get this working, you must download and install the Scilab VCP driver on your Mac and under Rumlog’s preference use the following settings for TX1:

 

 

 

 

 

 

On the Icom IC-7300 got to Menu/Set/Connectors/CI-V/CI-V USB Port/ and set Unlink from [Remote]. While there set the CI-V Baud Rate to 115200. On Rumlog’s IC7300 control screen you should see a Show Scope button. If everything is working ok, you should have a the IC-7300 scope shown on your Mac’s screen.  There are several tweaks you can experiment with relating to the scope on the scope screen itself as …

SDRPlay RSP2 First Look Video

November 22, 2016

First Look Video of the new SDRPlay RSP2. Featuring a quick overview of the new features. The RSP1 and RSP2 signal comparison was done in realtime using the same antenna attached to the RSP1 and RSP2. This means that there is some amount of small signal loss due to the splitter. The RSP2 antenna was connected to the Port A connector on the RSP2 to make the comparison as even as possible. According to SDRPlay, the RSP2 Hi Z port can perform a bit better on AM broadcast and HF bands. To make things as even as possible both the RSP1 and RSP2 were used with the default settings for each radio. Of course both the RSP1 or RSP2 can perform a bit differently depending on the tweaks you make within SDRuno. Also performance of the RSP2 may change as SDRuno is updated to better leverage the new features of the RSP2.…

Anan SDR Radios Now Available from US Dealers and a New Entry Level ANAN SDR

April 4, 2015

Some good news for you that have been interested in the generally highly regarded Anan series of SDR transceivers. First off, the Anan SDRs can be currently purchased from two us dealers, Gigaparts and Cheapham. The warranty on these radios are for 2 years against manufacturing defects with a US service center in Arkansas. Also earlier in the year Anan started shipping the Anan 10E. The Anan 10E is basically and entry level version of the Anan 10. The Anan 10E is pretty much the same radio as the Anan 10 with a few compromises to cut the cost to a more attractive price point for some radio hobbyists. Here is what you loose over the Anan 10 :

Differences between the ANAN-10 & the ANAN-10E
1. The ANAN-10E uses a 14 bit ADC while the ANAN-10 uses a 16 bit ADC
2. The ANAN-10E uses an EP3C25 FPGA while the ANAN-10 uses a larger EP3C40
3. The ANAN-10E supports 2 receivers while the ANAN-10 supports 7 receivers…

GNU Radio The Easy Way

January 14, 2014

Ready to take your RTL Dongle to the next level or learn more about how Software Defined Radio works? Try GNU Radio. GNU Radio opens up a whole new world of experiments you can do with SDR radio. GNU Radio also allows you learn more about how SDR radio works. Once you get your head around it, you can start building your own custom SDR radio applications. One of the show stoppers for a lot of people who would like to get involved with GNU radio is the requirement to install Linux on your PC. Then you have to download and build GNU Radio. This certainly can be daunting for those who are new to the Linux operating system. Well, you don’t really have to go through this anymore to experiment with GNU Radio thanks to Kali Linux.…
