The console works really well on our Hisense 55 inch 4K TV but that’s a bit over the top I guess John… Allan G3PIY From: main@SDR-Radio.groups.io [mailto:main@SDR-Radio.groups.io] On Behalf Of milairu

Would you need to synchronise the two tappers Alan? Maybe a couple of USB3 connections... Allan G3PIY

When you mention coherency do you mean one of these is involved? Allan G3PIY From: main@SDR-Radio.groups.io [mailto:main@SDR-Radio.groups.io] On Behalf Of jdow Sent: 06 July 2021 09:25 To: main@SDR-Ra

This was written a few years ago using my soundcard om. http://www.radiomuseum.co.uk/vlf.html (complete with a recording!) Simon’s come a long way since then and SDRs are a tad bit better than the SAQ

I’m showing my age I guess Doug, but at least I’ve weaned myself off Jars and now use microfarads. As a rule I use a term commensurate with whatever I’m discussing so an early English 1950s radio has

Oops.. wrong group Sorry Allan

After the RA!7 discussion a couple of old domestic radios arrived here for repair. I chose the Columbia C301, reported as having been in the customer's garage for donkeys years, and which looked untou

Way back around 1971 I was part of the 3 month study team for specifying and costing the Ptarmigan System. That was for British Army comms and was based on a brand new Plessey computer developed in-ho

Why not just use two different colour options? That would be visually obvious Cormac. Allan G3PIY From: main@SDR-Radio.groups.io [mailto:main@SDR-Radio.groups.io] On Behalf Of Cormac EI4HQ Sent: 21 Ma

You can get strange results with some files when played on different programs. If I play a 3-minute dashcam recording on Potplayer the audio plays correctly for 3 minutes but the video is slow and end

Hi Andrus I was a bit concerned before I checked the radio on a second computer as this was the example with a blown-up network chip that I had to swap a couple of years ago. My first venture in chang

All fixed Simon. You were quite right. It was Vipre. I didn’t know it had turned on its firewall. The clue was when I tried my Asus Mini PC on my 4K TV, adding Andrus caused Windows Defender to sugges

You may be right about the firewall Simon but I can’t figure out why. Recently I added a downconverter for my Lime SDR on one PC (the “bad” one) but it’s not selected for the Andrus but I notice that

Simon I tried my Andrus on a second computer and it works fine. My guess is I inadvertently changed some code when looking for a way to swap from Aerial A to Aerial B. I’ll remove all traces of the Co

About the time the Andrus failed I was examining the code associated with control of the Andrus to see if I could identify how to switch from Aerial A to Aerial B. I wonder if I closed a text reader a

I don’t believe it’s a firewall problem Simon. More tests needed but its looking like a really nasty hardware fault. Time to dig out the circuit diagram and an oscilloscope unless there’s an Andrus di

My Andrus SDR was working quite happily in my workshop, connected via my LAN until recently when it just stopped. Attached is the logfile from today. The thing is powered via its USB connector and eve

Why not simply make an analogue preselector Tom? Twin gang 500pF tuning condenser, rotary switch, a few coils with a FET to handle the impedances. Keep the current consumption low, a few AA cells and

Another trick is to shrink the SDR Console window to say a quarter size on the screen and see if the audio cleans up. I’ve been experimenting with an Asus N40 Mini PC with a Celeron N4020 coupled to a
