Some updated information was kindly supplied by Steve Ratzlaff. The current batch of available Russian ferrite rods are 400 permeability. But the desired permeability for MW is ~ 125. Fortunately,

Hi Gary, and All. Recently an Australian DXer constructed a 135 mm diameter MW FSL using forty one Jaycar LF1010 (9 x 100 mm) ferrite rods. These rods are more affordable than anything else available

Thanks Gary. Excellent information. For domestic MW fans like myself, the Traveler III is looking good. -- Bob Richardson

Thanks Gary. I happened across your excellent discussion of ultralights a few weeks back. Reading again just now, I might have to rethink the Tecsun only agenda. Or have some fun finding an original

I had a pair of binoculars that went the same way. I rubbed the sticky plastic with Armoural, a car interior treatment, and that did the trick. Steve

Thanks for the input. I like the antenna jack on the PL-310. But a simple induction loop would do the same. Non recessed tuning knob sounds good too. -- Bob Richardson

Thanks Gary, that's good to know for the future (not that I am planning to do any travelling for a while, due to COVID). j

It seems I have made a great error. It was not my PL-600 but my venerable RS DX-440 which has the rubbery push buttons.that developed the gummy decomposition. I don't know if there is a membrane under

Hi John, A "supercharged" Skywave refers to a model with a 7.5 inch transplanted loopstick. This modification greatly increases MW band sensitivity compared to the stock CC Skywave, transforming the

Hi Gary, I have a CC Skywave portable radio, but I am not familiar with what a "supercharged" Skywave receiver has that I don't have. What do I need to add to my travel portable? Thanks John Fisher

Hello All, When both the original PL-310 and PL-380 were introduced by Tecsun in 2009-2010 they were fully reviewed (at http://www.mediafire.com/file/w4yuzhj2kyz/Tecsun_PL-380_Review.pdf/file for

I do love the preset tuning on the 310et! Press a button to get into VM mode and tune through them with the tuning knob. So much quicker and more intuitive than the banks (Pages) of seven presets each

My PL-600 developed a bad case of gummybearitis and the cure is hi proof isopropyl alcohol as given above. I'm fortunate to own a few gallons of 99.9% so cutting it down with the appropriate amount of

I love the "Tecsun way" of tuning - I love the ETM feature on the smaller models, which basically works like "Page 0" on the bigger ones. Love that you can switch between dedicated VF/VM modes so you

As far as I know soft-mute can be de-activated on both receivers. I find the recessed tuning-knob to be advantage rather. If you travel a lot and take your pl-310 in an out of your suitcase
