Ham Radio Software on Centos Linux Configuring multitudes of Amateur HAM Radio software for Centos6 Centos5 Linux. Tune 7. 0 MHz to 6 GHz and GQRX Install. Yesterday we posted an unboxing and a few tests with the Pluto. SDR. On that post user rlwsdr commented and informed us thats its actually possible to do a quick hack that changes the frequency range and bandwidth from 3. MHz and 2. 0 MHz up to 7. MHz to 6. 00. 0 MHz and 5. Device Search Results. Returning 7879 matches for Empty search pattern. Returning all entries. Sorted by Device ID.

This hack has been confirmed by Alex Csete and others on Twitter and ourselves. It works for both RX and TX. Alexander Csete programmer of GQRX also posted instructions in a comment on our last post that explained how to get GQRX running with the Pluto. SDR.  Also in the last post we mentioned that all distributors were out of stock, but a few hours after that post went out Digikey restocked and they now have at the time of this post 1. USD price. Frequency and Bandwidth Hack. Thanks to rlwsdr and Alexandru Csete for bringing attention to this hack. It seems that the current shipping version of the Pluto. SDR uses the AD9. Usb2.0 Dvb-T Tv Stick Serial Number' title='Usb2.0 Dvb-T Tv Stick Serial Number' />MHz and bandwidth of 2. MHz. However, the higher end AD9. MHz to 6. 00. 0 MHz and 5. MHz of bandwidth is supposedly nearly identical to the AD9. The Pluto. SDR can be tricked into seeing a AD9. Its possible that the AD9. AD9. 36. 4 chips that failed performance QC checks and have just been rebranded as a lower end model, or that a cheaper silicon process is used with the lower end chip. Android-X86-2.2-R2-Eeepc.Iso. The instructions for performing this hack are actually detailed by the official Analog. Pluto. SDR wiki on the customization page. Just search for the heading Updating to the AD9. The instructions state that this is only for older Pluto. SDR units which actually came with the AD9. Pluto. SDR units that have the AD9. Simply plug the Pluto. SDR in, and connect to it via a serial connection. On Windows you can use a program like Pu. TTY for this purpose. First search in device manager for the COM port assigned to your Pluto. SDR, and then input this into Pu. E/F3/d43cdd02-d770-fa11-5679-3dcf492337e3.jpg' alt='Usb2.0 Dvb-T Tv Stick Serial Number' title='Usb2.0 Dvb-T Tv Stick Serial Number' />TTY leaving the speed at 9. You can then log in and set the environment variables using the lines provided in the wiki. Now in GNU Radio, GQRX etc you should be able to tune down to 7. MHz and up to 6 GHz and set the bandwidth to 5. MHz. Pluto. SDR Upgrade instructions. The images below show the Pluto. SDR serial connection screen and the commands you need to type, the Pluto. SDR tuning down to broadcast FM frequencies at 1. MHz, and a TX test at 7. MHz. It was found that the strength of the TX is a bit lower outside the official range, but can be increased by turning off the attenuation setting. Setting up the GQRX Experimental Branch for the Pluto. SDRFirst set up GNU Radio and gr iio using the instructions from this Reddit thread. Now install gr osmosdr gqrx with the iiodev branch. Install the GQRX prerequisitessudo apt get install git build essential cmake qtbase. Install GQRXgit clone https github. Now GQRX should be ready to use the Pluto. SDR. In the GQRX confiuguration screen select the device as Other or Pluto. SDR and set the device string as plutosdr0. Then you can set your sample rate and RF bandwidth, decimation etc. If youve done the frequency range hack then remember to select No limits in GQRX so that you can actually tune down further. Note that in VMWare Lubuntu we were only able to get stable audio from the Pluto. SDR and GQRX at a maximum of 3 MHz. Anywhere between 3 6. MHz bandwidth the Pluto. SDR and GQRX spectrum and waterfall runs smoothly, but the audio is crackly. Might be a VMWare problem, or maybe something that can be fixed in later GQRX releases. We also tested the Pluto. SDR together with the Spy. Verter upconverter for HF reception. It seemed to work well. The images below show the Pluto. SDR working in GQRX. The images of the 2. GHz and 1. 8 GHz bands show that there is little to no attenuation at the edges of the 6. MHz bandwidth, so the upgrade from 2. MHz to 6. 0 MHz is working well. Conclusion. So with this hack the Pluto. SDR is a much nicer unit that really makes an interesting and affordable choice for those wanting to upgrade from the RTL SDR. Combined with a Spy. Verter upconverter the unit should also be able to receive HF signals quite easily, so this gives a total cost of 1. DC to 6 GHz receiving system with TX capability, 1. ADC resolution and up to 5. MHz of bandwidth. Of course we still need to confirm what the performance of the unit is like, especially in the frequency ranges opened up by the hacks and in regards to strong signal handling. We will test those in the coming weeks. If it handles those well and other software developers support it in their software then despite the unit being advertised as a learning module for students, it might become one of the best and most affordable general purpose SDRs available.
