Re: Wanted : SR5
Incidentally, have you ever used a switching mixer without sn input tuned circuit of passband filter ! Paul, Yes, it will work. How well depends on signals at odd multiples of the primary tuned frequency. At 3 times there is an "attenuation" of about 9dB of the higher frequency, more as the number of multiples increases. (Due to the fact that at 3 times the frequency only one in three samples contributes to the output and less for higher frequencies.) Unknown will be the effect of strong signals anywhere. 73 Alan G4ZFQ |

There are very few resources on the SR5, but in the files section, there is just one reference. The only other reference that I managed to find is here :Paul, Yes, before my time. A lot different to the v6 when I first found Softrocks. Over the years I "upgraded" all my v6 Lites with plug-in BPFs and USB Si570s. Similar with my 6.1, 6.3 RXTXs. Nigel, I do not think any files have been lost. I did look at MediaFire but was not happy. Too many traps. I looked at my copy of the zip and it looks much the same as this group's File section including some Softrock 4 files, something else I'd never looked at. 73 Alan G4ZFQ |

Softrock Files Archive 2009
Nigel
Earlier messages similar to this are probably still buried in the messages section but I thought it might be worth another repeat, with apologies in advance if I got that wrong:-)
In January 2009, when the Yahoo groups file section was nearly full and there was discussion of the need for some heavy pruning of older files, I created an archive of all the then current folders and files to ensure they weren't lost. There will no doubt be duplication in that archive of some files still held by the group but there may be stuff that is no longer available elsewhere. Since 2016 this 90 MB zip file has been available for anyone to download from my account on Mediafire and I've checked today that it still downloads and opens ok....... Nigel GM8PZR |

Re: Wanted : SR5
Hi Alan,
I have lots of DDS and SI oscillators and want to experiment with! The SR5 is a very basic switching mixer, with a simple, RC phase shift , with two comparators , a local xtal oscillator , low noise af amplifiers and a plug in antenna filtering. I am mostly interested in the mixer and the audio amps. I can feed external fundamental vfo IQ feed, or, use an external 74AC74 to divide a straight vfo. Can be used as a simple monural rx, by feeding the audio amps to a TDA3820 stereo amplifier, etc etc |

Could you give details of the softrock kits and cost of shipping to denmark ? regards Helge Kyndbo Den tor. 4. feb. 2021 kl. 10.06 skrev Nigel via groups.io <poldhu1901= [email protected]>: You don't say where you're located but I have four as new unbuilt Softrock |

Re: Wanted : SR5
Nigel
You don't say where you're located but I have four as new unbuilt Softrock 5 kits in the UK.
There are four QSD boards with components and two each oscillator filter boards with components for 80m and 160m. These are part of a large number of Softrock kits, built and unbuilt, that I offered for sale here in January 2019 as a complete collection. I was asking 200 GBP for the lot, approx half new price, which I still think is a very reasonable investment given what I've seen individual items selling for, but I had no response. That offer still stands, and full details are still in the group files section, but I'm not currently looking to sell any items separately. Nigel, GM8PZR |

Re: 2 HDSDRs on one Softrock receive.
Alan,
Got it working - created two separate folders in C: drive, Decoder 1 and Decoder 2 each containing a copy of of HDSDR/Multipsk. As you mentioned I set the LO same for each and then tuned one to 2187.5 Khz and other to 2177 Khz. works great... Thanks again 73, Peter g3ufi |

Re: 2 HDSDRs on one Softrock receive.
Can I add another instance of HDSDR and now tune this to 2177 Khz (DSC) and decode separately/simultaneously? I have internal sound card plus VAC. There seems problems with Config tool Si570 not opening in second HDSDR?Peter, Presuming the soundcard will share then I would try a separate profile with no DLL selected. Set the LO to the same as profile 1 and tune separately. There is no need to run the ExtIO twice, there is only one Softrock. 73 Alan G4ZFQ |

2 HDSDRs on one Softrock receive.
Hello,
I'm using a Softrock LF/HDSDR setup tuned to 2187.5 Khz (DSC decoding) works fine. Can I add another instance of HDSDR and now tune this to 2177 Khz (DSC) and decode separately/simultaneously? I have internal sound card plus VAC. There seems problems with Config tool Si570 not opening in second HDSDR? |

Re: help needed for getting RX Ensemble II running in Ubuntu 18.04?
Ignore the messages, they appear every time quisk is started. A short explanation is that it checks for stuff that doesn't exist ... we call it "Just Noise" generated by the program.

What versions of quisk and Ubuntu? You mention an old Ubuntu, trouble with that is not only the OS but applications develop at pace so that old and new can become incompatible. In your case it seems there isn't a compatibility problem. Newer versions of quisk use the CONFIG tab rather than the old ~/quisk_conf.py file. These later versions write and use a ~/quisk_settings.json file. If the bands are not switching it suggests that a fixed frequency Softrock may be configured. 73 ... Sid.
