Another thought which might be relevant. I was struck by the relationship with telephone lines. A few years ago I had a box installed by the "telephone company who used to be a post office" that crea
6 or so turns of the drop wire through a ferrite ring seems to help keep my HF out of my ISDN lines and doesn't seem to affect the line comms. But there again I don't seem to get any problems from th
Touche, Alberto! The probem is (as my pal G3nyk often reminds me) is the misconception of what is referred to as "common mode" transmission of unwanted products (and sometimes "stray" wanted ones as
I just wish that there were some evidence that a lot of these "compact" antennae are little more than one half of a capacitor coupled to the rest of the universe! Have a nice weekend all g4gvw
Hi Mike, have you tried any of the major electrical wholesalers eg Newey & Eyre, Wholesale Fittings, etc.? Years ago people like BICC and AEI used to do them so it might also be worth enquiring of so
Sorry Mike, though a recent "joiner" I can't remember what was received. It just "worked" from day one so I guess it must be user friendly for a lot. Perhaps a very new internet user might need help.
Hi Mike AOL 7030 But as this was at the recommendation of Alan G3NYK he would be the best one to comment and his opinions would do for me as well. All in all I think it's a hell of a Rx at any freq i
Actually it may not be such a daft train of thought. Disconnect tower grounding strap(s) - there should be at least one (inteded to "arrest" lightning ?) and check to see if tower really is "earthed"
I think it is probably time to thank everyone who has contributed(?) to this topic and move on to the less emotional pursuit of scientific knowledge with a little less of the "biggest/best/first" arg
Actually, Mal, 76 Amps (if that is the true figure) may be accomodated with good materials and equally good engineering practice. However, the argument then becomes a debate about economics and retur
Yes, well Brian, The "most of us" I should have identified, I agree, are those who have a soldering iron almost as close (closer?) than a microphone or key! However we mustn't be that politically cor
Actually, that is not strictly true. If an experiment does not agree with theory then both the experiment and the theory need to be re-evaluated and both require validation and revue by a peer group.
Well said Bryan! From my early days in radio I was led to believe an old adage: "Cover the sky with wire!" In what is now almost 50 years of involvement, it still seems to apply and stand me in good
ROCK ON ! Bryan. I am also contemplating a box with little electric fires in tiny jam jars which screams out for modding to LF. p.s. The electronics looks easy but in which opening do I shovel the co
Thanks John! Now I know that, I can set up some instrumentation to measure mod. depth in fathoms but a really neat trick gets me reading QRSS in kph (or mph) subject to parallex error on my trusty Fa
Actually, joking aside. I have on the bench a Trio(Kenwood) JR310 which has a very (?) stable VFO which might be further improved by "huff & puff" stabilisation (already discussed with G3nyk). The VF
