    Anyone try TENAVOLTS Rechargeable 1.5V AA Lithium Batteries?

    Tried them in a portable radio and, as feared, RF noise from the buck circuit inside nearly totally obliterates reception on the AM band.

    EDC Pen?

    This is certainly a cheap, very popular and enduring product. People seem to have a love-hate relationship with them, though; if you look at the EDC and pen forums where are a lot of equivocal comments: The 0.38 and 0.5mm tip are far too scratchy The 0.7 and 1.0 mm tips tend to feather, blob...

    EDC Pen?

    Well, months have passed and I never ordered the clicky from Big Idea Design. I did play with some very nicely machined Chinese solid brass pens sold on Amazon under brand names like "Copplus" and "Ekloen", but in the end decided that so many of the machined pens were simply too long to fit in...

    Small Portable Radio's?

    Not possible AFAIK, it's locked to the Japanese FM band (76 - 108). Narrowing it beyond that is just a matter of convenience anyway.

    Thomas has posted a preliminary evaluation of the CCRadio3 on the SWLing blog. By his account, the RF performance is identical to the 2e; its design purpose appears to be more of a "feature upgrade".

    Jaycar, an Australian electronics dealer, carries this and other models under the Digitech name. When the Skywave was announced, the exterior was noted to have an uncanny resemblance to the AR-1733. But a side-by-side performance evaluation and actual teardown of both models revealed that they...

    The Elpa is not a Skywave clone. It is the same as the Digitech AR-1733, an underperforming model (poor AGC implementation) whose cabinet was the basis for the Skywave design but with totally different circuitry. There is no reason, in todays market, to spend US$70 for this model when there are...

    Small Portable Radio's?

    Yes the UI is entirely different, but according to teardowns by Jay Allen and others, they have copied the basic DSP design of the Skywave SSB into the D-808. This is the reason why they dare not officially distribute this model in the US. Another brand-new model from an XHDATA-related brand...

    Small Portable Radio's?

    Look at this one. Sold out on Amazon, it's available on eBay for mere pennies. Also sold under brands like VITE etc. Manufacturer at http://www.radio668.com For the price I couldn't resist. Even has an (undocumented) key sequence to change the MW step rate from 9/10 KHz. While the noise floor...

    Most of the recent CCrane radios have been made in China by Dongguan Redsun, who produces radios under their own Redsun brand. In the past, Redsun even had equivalent models to the Ccrane offerings ... until now ... so instead the company that produces some sets for Xhdata just went and copied...

    Since Sangean has markets on several continents, many of their sets have the feature to change bandplan but sometimes it is not well documented.

    Ultratac K18 v2019

    I can definitely share some numbers for weight and dimensions. Photos will have to go onto my to-do-list at this point. As regards the choice of SS - This has become a matter of changing personal preference for me. In my eye, nothing looks uglier than an aluminum flashlight whose anodizing is...
