Imagine Microsoft having a simple email service for reporting problems with Windows... it would be impossible to service. Most suppliers of services, for example Sky, have abandoned email enquiries an

Hi Tom I may have found a clue to what’s happening. The SDR will only drive one PC at a time. I checked 198KHz in the office (Win 7) at -63dBm then switched off Simon’s program. Went to the workshop a

Hi jdow This all started when my long wire developed a fault somewhere along its length and one day I lost loads of signal. I started experimenting to see if I could work out where the problem was and

Hi jdow When you say “server” do you mean the network chip (KSZ8851SNL) in the Andrus SDR? It’s decades since I designed data equipment and times have changed (I have a patent in the field US4035601A

Hi Tom I tried removing the switch in my workshop and feeding the SDR directly to the incoming CAT5 cable from my office (about 80 feet) The office computer gave me the same results as before with the

I've been using my SDR which is an Andrus on my Windows 7 x 64 office computer and have recently used it on my Windows 10 x64 workshop computer. The Andrus (powered by an adjacent 6 volt PSU) is in my

Hi Max Yes, a duff capacitor. Most PSUs develop a low voltage from rectified mains for control of the chopper circuit. This voltage is maintained by something like 47uF and this gradually loses capaci

Cracked it Sigi A few weeks ago I fitted a new Ethernet switch to give me more ports and I used a spare old one using a non-standard coaxial power supply lead. The PSU was obviously failing and althou

For the last few weeks I've had trouble with our radio clocks and the reason is a very strong signal around 58KHz which has evaded attempts to find its source. I assume that it's local interference. P

The film that followed on the Mullard EF80 showed the incredibly complicated machines developed for making the valves. Very impressive. Allan G3PIY

I agree Ulli. Home brew construction is becoming a dying art. I really enjoy building things but you do need half decent test equipment to see how your stuff performs. http://www.radiomuseum.co.uk/dc.

The life of the bulb is up to 25,000 hours so a life of 10 minutes would come within that time span? Presumably the FCC rules for a residential installation are less severe than say an aircraft or a s

I last dabbled with my Lime over a year ago but I did have to use an external power supply especially for transmit. The external PSU stopped it crashing. Allan G3PIY From: main@SDR-Radio.groups.io [ma

Hi Paul Very interesting video. I bet things could have been improved even more by adding a filter at the output. That baseband modulation would drive me round the bend. Is it from a local AM broadcas

Thanks Jim If we have trouble I’ll get him CAT6. At least the holes in the ceiling will be there by then. You can see us at BH23 8DU. You can just about see my mast for the 80m inverted V on the chimn

I notice Jim has two 80m dipoles at right angles, a top band dipole plus an 86 foot vertical in his back yard. Allan G3PIY

A bit of potential good news re my HF interference from Ethernet-over-mains adaptors. Whilst installing a new graphics card for my noisy neighbour I noticed he already had a wi-fi extender behind his
