Re: CuSDR64 v0.3.3.0 (Feb 2017 Release)

Hi Rob Totally agreed. It's a really nice interface once you have found how to deal with "right click" parameters. The lacks of audio processing is indeed a major problem (unable to demodulate any signal with my Hermes Lite). I hope this feature will be soon added to the project. Pluging a...

Re: Anan 10-E remote operation.

Ah, Scott... you're a terrible devil's advocate I don't want to "fork" this thread, but yes, indeed, at the end of the day, my software client (well... sort of if I consider my ugly GRC applications) could have perfectly run all the day long without receiving the smallest audio stream. (I'...

Re: Anan 10-E remote operation.

Agreed Scott I don't know any client software that reach the level of quality and user's experience that PwrSDR Mrx gives us. I was just explaining that a "heavy client" was probably more efficient than a "super-duper-heavy client" like a remote desktop based on RDP (I'm using Ci...

Re: Anan 10-E remote operation.

Hi I would be very cautious when configuring an RDP (or it’s Citrix equivalent). These proto have not been developed to transmit stream oriented applications (that’s the reason why both editors have developed rather expansive streaming dedicated servers). The speed of the Windows interface via such ...

lcd arduino signals

Hi Yet another stupid question : Digging into the modified ON7EQ code for the Hermes, I was wondering where the signal TXRX_Status (IN_PTT variable, pin A7) came from? - TXRX_Relay line (bufferized and probably inverted ?) - PTT line from Alex 10 points header - Another mistery signal fired by the S...

Re: Lost in 100D signal path

Once again, thank you for your answer Scott I feel a little bit stupid asking you what seems obvious to you (and all other SDR users). Firmware and hardware in the whole Hermes line looks... as entangled as a pair of Qubits in quantum communications :-D I may be wrong, but I think that a good docume...

Re: Lost in 100D signal path

Hi Scott Thanks again for these very clear explanations. I couldn’t find anything looking for a “changelog” file giving these infos. I’ll modify my personal version of the manual to take into account these mods. Just one last stupid question (I hope) to complete the “big picture” Where the XVTR TX s...

Lost in 100D signal path

Hi I’m trying to understand the incoming (receiving) signal path of the Angelia/100D… and I cannot kill the 3rd level Boss. Where am I making a mistake ? Using the 100D schematic (100W PA Rev 24) Signal enters at Ant(1/2/3)==>goes thru the LPF==>gets out of the LPF (label “line LPF_IN”) ==>crosses t...

Re: RX filter problem

Hi Clyde Many thks for your answer. Totally agreed. Building filters is always a tradeoff between best NF, best match, best phase behavior, IMD, group delay... But why these frequencies? <sarcasm > why adding a wonderful predistortion mechanism if your F2 is as strong as without filter </sarcasm> Mo...

RX filter problem

Hi Did someone really measured the IL of HPSDR/Hermes/Angelia/Orion Mk1 filter ? I’m trying to understand how is working the RX filter of the HPSDR family (and by consequences all the Anan series except the 8000DLE) HPF are almost perfect, the distribution of all filters from 1.5 to 64 MHz has been ...

Re: multiple & chained RX slices ?

Hi Scott My Angelia is not really operational right now, if I could dare this understatement. The main board is empty of any component (we are collecting the BOM for a batch of 6 boards) and I'm right now designing the front-end with Kicad (I've decided to follow your advice : sophisticated filters ...

Re: multiple & chained RX slices ?

Thank you to both of you. It helps a lot. Now I have to know how can I add 2 or 3 receivers :-) 384 kHz is definitely too "narrow band" for me. I'm trying to display (and later decode) a 400 kHz modulation scheme... no obvious with PSDR. I think the truth should be found digging in GNURadi...

multiple & chained RX slices ?

Hi couldn't find in the whole documentation (or in the setup of OpenHPSDR mRX) how I should configure the software to run multiple chained 384 kHz receivers. something like VK1HW's video on https://sites.google.com/site/vkonehw/home/radios/anan-100d/win10 (bottom of the page) If someone could give m...

On the other hand, I've tested his diplexer filter.... could be better compared with a WB6DHW (himse...

Re: what kind of filter for Angelia board

Thank you, Scott. Many aspects of the architecture are crystal-clear now. You are right, I haven't been precise enough when I was speaking about "RX2"... I meant "the second receiver path using ADC 2"... the fact that any ADC could be used is not important/significant when consid...

what kind of filter for Angelia board

Hi I’m trying to design my “next SDR” with an Angelia board (built from component level) and some aspects of the Hermes/Angelia/Orion architectures go beyond my understanding. Particularly the input frontend Initially, every HPSDR/Hermes/Angelia and Orion MK1 was using a combination of lpf and hpf t...
