I’m using a Belkin Tunecast II, with the longer antenna mod, and the quality of the audio is terrible. The coverage is not too bad, but its full of. the Belkin tunecast 2 FM transmitter can be modified to extend the transmit range. It can put out over milliwatts of RF power and be heard.

Two different tutorials on modding the Tunecast II transmitter by adding a more effective Antenna. But on the other belkin that i have not even opened yet. This step is a bit trickier, it involve adding a switch, a resistor and some wiring. I just recently did this with the instructable listed in the first post.
How is it holding the transmitter? When the unit is assembled, mox coax can be routed out the hole where the audio cable is stored.
Could you plz explain in a lil more detail what exactly you do with the black and blue wires? For instance, I know how to do the mod at least on the older units which have the antenna pad available and labeledbut it seems to me that using the recommended 36 inches of “medium gauge speaker wire” i.
With a fair bit of filing and drilling, the end result is show in the photos below.
I believe that one of those wires is a ground. S Unless there’s a way to bypass the volume threshold through a blob of solder, I’ll have a look at that chip datasheet One could also connect an external antenna to pin I mean remove C38 breaking the circuit there, not shorting across C38and take the output directly from the chip. If this range from the roof does not improve the reception significantly, I’ll push foward with my 6W amp. I assume the center, solid copper, wire.
Now if you wish to take it further, get a telescopic antenna! Anyone know if, and more importantly how, a tunecast can be modified to be powered by a PC power supply or the ebay power supplies that Kevin had shown on he website?

The question is how about the battery life and how far will it transmit? Yet the second article connects it directly to a 50 ohm line.
If so, how did runecast go about it? I cut the blue antenna line at 2cm. Seems to be working well so far.

These plots were made with the better MRF output stage. D If it’s the right thing to bypass, shouldn’t I solder the new antenna both there and to the old antenna contact? Maybe Belkin met the same fate and greatly reduced the power?
I’ll be doing some further tweaking to see if I can improve the range. Open it up, find the FM transmitter IC, find its datasheet and examine the circuit. Solder it onto there. Yes, the internal antenna is very short and an external belkjn would help a lot.
That wire comes out of the hole in the case, and is used to broadcast the signal. Does anyone want to verify this?
I soldiered a 32 inch piece of wire to the left side. This is my first upgrade using instructables, but tunecqst my last. Im looking to get around 1 kilometer so my friend can tune to my internet station,he doesnt have internet. Not sure if you are set on powering from PC or not, but this is what I bought off ebay.

Antenna’s are beljin things, and I don’t know much at all about them, just what I ended up using, because it worked ok. What did you do with the other end? The result is this: Yet to do any mods as other projects are more urgent. Why is the signal so week this close to the unit? If you have more questions after looking at the instructible, let me know. The gray bezel around the front comes off and the screws are under there.
