you're not alone :( a number of those relatively "cheap" receivers, seem to be on the same boat; after some time, they start having problems <deep sigh> the times of the Yaesu, JRC, Kenwood, ICOM and other receivers are past, modern ones seem to be designed with a "preprogrammed life ...

oh... and as for the receiver, did you consider the "Belka DX" ?

not a JRC by the way, but not all that bad, either; you may consider picking one of those and sending your JRC to Thomas' friend Vlado for cleanup/repair/alignment

Thanks to all who have responded. The NRC-535D is getting "tired," kind of like myself. Keys sticking, seeming loss of some sensitivity (though I don't have anything comparable to test) and maybe it's just time for something newer. No garden space at the new house; all the outside is pool...

ok... but you can still use the old "tape loop"; pick some wire, form a loop on the inside (glass) of a window... I've done that with the reel-up antenna that came with my Tecsun PL-880, but it didn't work as well as The Square. I've yet to try an active antenna. What's your opinion of th...

Thanks for that! This is absolutely something I want to play with, it's easy enough. Couldn't you have posted that before I bought this expensive phasing unit to make experiments with the original ADF antenna principle (loop + sense antenna) at the dike? :D I'm sorry !! Truth is ... that I found th...

Like that? :) LOL !!! Well, yes, that may work, but I was thinking at a vertical support with an horizontal bar nailed/screwed and the wire running around in a diamond loop shape (That's a YouLoop with a LANA-HF, temporarily mounted on a boom outside for a test. That's all plastic cable duct profil...

Ok, got a bit of time and "massaged" the original NEC model a bit, the resulting model is here CM Cardioid loop design by Chris Moulding G4HYG based on original C & S CM loop array design from 1982. CM Loop size (side), height and resistor value can be adjusted in the Editor. CM This v...

Thank you, Andrew, I´m afraid I´m a little "mechanically challenged" but I´m going to try. Some months ago I tried (following the good guide posted at swling) to make an own Youloop but I found a random wire half in- and half outdoors worked even better. I´m going to use its parts to see ...

That's a pretty interesting design, thanks for the heads up! I wonder if and how this principle could be applied to big loops (because I find SMLs tend to lack a lot above 10 MHz)? well, the NEC model (which I used for tests) was related to the bigger loop, optimized for 160m and down, and that ver...
