Hi Garry, I had been thinking about spider coils also for an ultralight. How large of a coil form do you think would be needed to compete with a hot rodded ferrite loop? Also, do you envision concentr

Message These are interesting findings on selectivity of the E100. I wonder if the E10 is similar? I have an E10 I picked up at Fry's Electronics for a measly $29.99, and I've been impressed with its

Hi Gary, Hearing that probable Aussie on 531 with the stock T-615 is really cool! I checked the Grayland Master logs (skillfully compiled and maintained by Chuck Hutton) as well as my own logs for 531

Don't forget the similar, but larger E10 model, which is a hot performer also. It's size perhaps takes it out of UL status, yet it has a lot of good things going for it. The radio has TWO bandwidths,

For those interested, the E100's replacement, the E1100, is available in a Tecsun-badged version from Ebay seller "Trinityforevertrading". The price is $12.99 with $13.00 shipping from Hong Kong. Chec

Sorry...I gave the wrong auction number. The correction one is: 370045350485 Guy

Hi Huelbe, Well, that is disappointing. It sounds like Eton/Grundig is going backwards, if they are just rebadging a year and a half old radio. However, perhaps the sensitivity is just a matter of ina

Wow, great post, Allen! It brought back fond memories of my early days at the dials for me, too. As luck would have it, this summer will be my own 40th anniversary of DXing. It was on a camping trip s

Hi Dennis, I have owned a E10 for a while, and today received a couple of E100s that were display models (got 'em for a song). I believe John Bryant has the E10 too..and we both have the big brother E

After three mornings of getting skunked on TPs/DUs with my hotrodded Eton E100, I finally hit paydirt this morning. I've been on a family vacation to Yachats, Oregon since last Friday and have been tr

John, Of the few links I spotted with info on this topic, this one was the most concise: http://www.eng-tips.com/viewthread.cfm?qid=190262&page=4 Diamond blade cutting with lots of coolant seems to be

Gary, Great going with those super catches! I will have to check out the recordings. That was quite a feat and must have been a lot of fun. I look forward to getting closer to the coast again...I am i

Hi Gary, Unfortunately I have no useful information to share on the SRF-M37V alignment. This model was the very first one ultralight I tried to align, and in so doing I reduced the sensitivity somehow

John, FYI, the Murata filter we love for the E100 is nominally 2.3 kHz, not 5 kHz. I am sure you know this...it was probably a slip o' the typing fingers. Guy Sent via BlackBerry from T-Mobile

Stephan, It was that plot you reference, by radio amateur KK6IL, that convinced me this filter is an excellent choice for upgrading my E100. A shape factor of 1.4 is *excellent* for a ceramic filter;

I hope it's OK to mention this on the Yahoogroup, but I'd rather sell the following radios to Ultralight enthusiasts before listing them on Ebay. Since I use my Eton E100 and other larger radios almos

Gary, Is it possible to adjust the 1400 kHz trimmer by alternating between disassembly as needed to access the trimmer, making a small tweak to the cap, and reassembling it enough to check? With enoug

Gary, Just another thought on this. What I did on another radio I've owned (can't remember which model), I noted that there was a small amount of unoccupied PCB directly above the trimmer. That is, th

A reply I received from RadioLabs this morning seemed to indicate they not only couldn't they supply the specific filter I was asking about, they won't be selling any parts to hobbyists. I contacted t

Hi Tim, Actually, most if not all modern, portable AM radios have the same adjustment point. I've made the 1400 kHz trimmer adjustment on the SRF-T615, DT-200VX, and the E100 models, for example. Thes
