Aye, Tickmike, I regularly dial up the BT"quiet-line" number, & everything is tickerty-boo. ADSL problems is my beef.
       3 years back, myself with my DF Rx & an experienced older OR guy with his LW/MW Tranny walked up the road a bit & easily detected the RFI from a neighbour's menarge & paddock. Also, for years it can be heard on my big static Eddystone 730/4 Rx. Thankfully they are one of the neighbours, further along, who have recently told BT to "stuff-it" & changed completely to Vodaphone 4G. Over the 2.5 miles back to the exchange there will no doubt be sheep & cattle electric fencing in odd places. I also know of at least two grain drying sheds with either 480V split-phase or 415V 3 phase machinery. As I said in an earlier post a few days ago, I plan to "walk the line" back to the edge of the village, weather permitting sometime, & see just what I can detect RFI-wise.
      Mind you, a big article in today's local paper - - BT just awarded a huge 385 million contract to quickly roll out FTTP to remote areas, with Scottish west coast islands & the Highlands getting priority ! So Weaver's problems will soon be over, & he'll be able to flog off surplus ADSL enhancing stuff to us lesser privilaged mainland teuchtars.
       Re my BT & domestic computer equipment - all info on page 2 a few posts back.

Hey tickmike, as I've said in a few posts - I'm just an old analogue guy. Computer software & Modem software, etc. are way out of my spectrum of electronics/radio/telecoms knowledge. In the 21st century, such equipment is just a tool to enable me to generally communicate with family & friends, plus carrying out research, or passing on info regarding vintage radio/electronics pursuits. Right enough, I'm endeavouring to understand telecoms-speak regarding my stumbling current venture into ADSL & it's problems. About 55 years ago, telecoms-wise I did do some training on RAF teleprinter servicing & learnt the Murray Code. Also did some basic servicing on PBX equipment. we're talking 1965 not 2020.
       Want in-depth knowledge on testing & Gm graphing an 807 Beam Tetrode ? - - -   I'm your man. Need some spares for a 1930 TRF Rx ? - - I'll see what I've got on the shelf. Want info on wee micro-chips, virtual modems, and QPSM ? - - -  I'm just a thicko compared to you chaps on this forum.

                                                                                         Regards,  David

I noted the reference to an Eddystone 730. I had one of those beautiful kit. I assume you can still source the valves to keep it running.

I made loads of stuff including linear amps for 430mhz. Using the forced air 4cx150 triodes. Great fun and lots of 2.5k power supplies ! Tony

Hey Tony, get your arris also onto the VRR&R Forum. Heaps of guys would love to hear about your great linear amp projects. Re the Eddystone 730/4 Rx - - if you've got a suspect valve or two, let me know & I'll see what I've got. Also there is a dedicated "Eddystone" site, which can source many a spare replacement item.
       Apologies to Mod's for drifting O/T. Mind you, thumping big Triodes are still in use today for "line of site" transmission of VHF/UHF Telecoms. Likewise, thumping big Beam Tetrodes & Pentodes for LF & HF terrestial work. Then you've got Satcoms & Troppo & God knows what. 50W out of 3 parallel 807's is all I've got out of my restored 1950's Coastal Radio Nimbus AM HF Tx.

I thought I'd heard the last of 807's  :P

This house I'm building I put some 807's, ECC 83's etc. and others along with un-wanted electrical stuff in voids in the house  ;D some one is going to have a shock if ever these voids are opened up  :)
