EDM Transmitter

Recommended Posts

Yeah I read the manual but you know how they are always over cautious in manuals. Once again I'll trust real world testing. No reason to go out and buy a cable to extend the transmitter away from the PC if you have great sound. And I just checked the output level on my laptop...it's at 74. But there are right and left input gain pots on the EDM and I had adjusted mine down as part of tuning my signal. Just look at the attached photo. The EDM is sitting in between a 27" monitor and a laptop behind a Bose speaker and almost on top of a backup hard drive....and it's working great.

And I see someone else just posted that they built a dipole antenna and it's working great. So there's 2 of us.

what kind of an adapter are you using to plug into the transmitter? the test antenna looks like an RCA plug but longer so how are you plugging in Coax? I've been to Radio Shackand they can't seem to figure it out. Thanks in advance

Can one of the experts answer the coax directly to the transmitter antenna portal. The test antenna pleg looks very unique. Is there an adaptor that is used or how does that work??

Just remember, to have a broadcast transmission be very effective, a properly tuned antenna, coax and connectors will need to be 50 ohm. Most of the ones you get cheap are 75ohm.

okay, so 50 ohm, coax and 50 ohm antenna...as long of a male end that is on the RCA plug for the test antenna, i wasn't sure that basic Coax F connector to RCA would work since the male end of the RCA plug is shorter. Thank you for the help

You can pick these up from our friends at Radioshack depending on your needs.

Coax F connector to RCA

Or put one on your RG59 yourself

Thank you the input, wasn't sure the RCA plug was long enough as it is shorter than the plug on the Test Antenna..but perhaps that is a non event and I will go with what you guys are saying...thanks again

I had my volume up at 75%. I turned it down after reading this. How do you know if your EDM is fried? I still get a signal with a noticeable hum. I still have to cut down my antenna to fit my frequency, so I'll test it further later.

Did you try turning down your output volume from computer down to say 20-30%. I don't have an EDM but if I have over 30% on my cheapo transmitter mine distorts pretty bad.

Yes, down to 20-30%. I have a new antenna that needs to be trimmed down to the appropriate frequency. I'll update after I do this.

I had a hum problem with my xmiter and it is not an EDM.. turned out to be the jack on my laptop.. I would up giggling the plug by accident and the hum went away.. completely gone.
