taybrynn Posted October 20, 2008 Share Posted October 20, 2008 A transmitter review posted in late September on the EDM yahoo group:Cmments: I would note that this was the EDM LED and not the EDM LCD. The EDM LED is the lower-priced legacy transmitter and is somewhat lower-performing than the EDM LCD in all regards. That said, the EDM LED costs less and still delivers good performance for the money. It is also available in a 1/10 switchable power version and a 10/100 switchable version. This is switachable power, not fully adjustable power like the EDM LCD has. For those looking for the performance of the Ramsey for an even more modest price, the EDM LED could be an option ... and shipped, the 10/100 version with metal (not plastic) case and power supply is around $130 shipped.Well folks, my EDM LED xmitter showed up this week end. Took meabout 15 minutes to get it soldered up and running. I have had aRamsey FM25B for about three years now, and always loved its clarityand range. I was a faithful Ramsey owner. But, I've read thereviews by Steve at Radio Brandy. He's always raved about thislittle xmitter so I thought I would give it a try.My usual set up was, Dell PC running Zararadio playing my eclecticcollection of 1940's swing, Heavy Metal, Sousa Marching band musicand Beethoven. Nice collection huh? the signal went out of the stocksound card into a mini stereo Compressor/Limiter - into the RamseyFM25B transmitter. Then the output of the FM25B through 75 ohm coaxto a Dipole antenna I built myself using PVC pipe with the internalsbeing two hunks of Steel measuring Tape carefully cut to properlength. The positive to the upper hunk and the negative to lower.I hooked up the EDM xmitter through 50 ohm coax to a second dipole,again the dipole sections were cut to proper length. Nocompressor/Limiter. Just, computer - EDM - Antenna. I then got inthe car and went for a drive.I called the wife and asked her to flip the 'switch' I had setup.This switch was simply to flip the signal coming out of the computerfrom one transmitter to the other.To the left - Ramsey, to the right EDM.It was that simple.I started with the Ramsey, drove out about eight blocks until thesignal really started to fade to nothing but static, then switched tothe EDM. The signal improved immediately. Wow.The final results are these. I was able to get a 'little' more rangefrom the EDM. About a half a city block in all directions. So Ihave expanded 'good' listening range from about 4 blocks in alldirections to 4.5 blocks in all directions from ground zero. But, thereal difference was the astounding sound quality improvement with theEDM xmitter. Hands down, no comparison. The EDM truly does rivalthe sound of a professional station. I never realized how thin theother transmitters' sound was. I'd compressed, I'd Limited, I'd EQ'dthe snot out of my signal to get the BEST signal I could through theFM25B. The EDM is running NO external compression, or limiting. It'slike drinking Concord grape juice for three years then someonehanding you a glass of fine wine - WOW. As usual, Steve's advisedidn't lead me astray. A special thanks to Steve for his diligenceand sharing his knowledge, and thanks EDM for such a fine product, Iam now a faithful EDM xmitter owner/user, my FM25B is now apaperweight. I hope to have my new studio redone soon and willupload pics when it is.
