The Chinese-made Radiwow R-108 is a very compact AM-FM-LW-SW-AIR portable which has recently become available to North American purchasers via eBay, where it is currently offered at various prices

Paul, You should try for 558-Radio Fiji One around your local sunset after 7BU stops transmitting on 558. The native-language Fiji station was recently supplied with a new 10 kW transmitter, which has

When I did a 1-Transistor project in 2004, the only thing on 1690 was WPTX running CNN-Headline news. They went live IIRC in '05. Then Canada put two stations on 1690... Montreal and Toronto and

The older and later 'pocket radio' designs were both made with a mix of price and quality. Older designs had weaker transistors/tubes and needed a high quality ferrite coil winding. A pocket model of

Were your widely spaced windings made with Litz? I think wide spacing lowers self Cap. and so does using Litz. It was awhile ago I looked at Online photos showing the winding on PL-450 and PL600

Thanks for the heads up on this. On 558kHz you should be able to hear 6WA from Wagin at night. I'll try to make some recordings of 7BU & 7AD before they are shut down.

I've tried both ways of winding. If I remember correctly, I get better signal pickup with a winding that is the full length of the ferrite. That said, I'd be curious to know the purity differences

In the next couple of weeks 7BU is going to FM and will be on 100.9. 7AD will be on 98.9FM. I will be keeping a close ear on 558kHz and 900kHz during the change to see what stations them shutting down

You guessed correctly!!

Except for one broadcast station at 1650KHz in Southern Los Angeles County, everything I hear in the extended ban is Part 15 and therefore DX past a couple of miles - local community service

The "extended" AM (MW) band (including 1610-1700 kHz) was approved for North America in 1988. Receivers typically did not tune beyond 1600 kHz before that. The first extended band station in the US

That sounds like an interesting radio. -- Paul - Moderator UltralightDX

A lot of European radios from my collection have unusual windings, and excellent performance, including radios with coils at both ends of the ferrite. Some time ago I looked for internal Online

I've accumulated portable radios dating from the 1950s to the present. I've noticed that in general, older radios were usually wound with the turns widely spaced. I have an old 8-inch ferrite antenna

My guess is it was never meant for North America. I don't know what other parts of the world have MW up to 1710 KHz. I would guess it is intended for Asia, Africa or the Middle East, but that is just

Interesting radio. I wonder why it doesn't cover the entire "Standard Broadcast"? Maybe they found a container of pre-1980s analog tuners and decided to build a product instead of land-filling

Yes, it's not an ULR, but it is interesting to me anyway. I have a collection of a dozen or so 2 D cell portables. https://radiojayallen.com/panasonic-rf-562d-retro-design-am-fm-sw-portable-radio/

I will just update my links and focus on my new one. -- Paul - Moderator UltralightDX

The phrase is Indonisian... "There is nothing here." So they dumped it... Wonder if blogspot.com can delete it? Best Regards Phil KD2HTN / WA2069SWL ______________________________

Yeah I can't work out how it even happened. It must have been in the past few days. -- Paul - Moderator UltralightDX
