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...

Ok, being curious decided to download the NEC model file from the CCW page and ran it, found that the impedance of the antenna in the range between 1KHz and 10MHz varies between 600Ohm and 1KOhm, so I ran a sweep setting the feeder impedance to 800Ohm that is feeding the antenna through a 16:1 BalUn...
