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.

They claim it lasts up to 10 hours so when putting in a new set of AAA batteries the current reads about milliamps then as the batteries drain, goes tuencast to maybe milliamps then quits.
Ino this is mmod to you guys but thanks for any help. Hello again to all. Modding the case to fit the switch. If you live in the UK, Maplin Electronics www. As far as I know the tunecast has a regulator in it. As promised, with this feature allows you to ‘swamp-out’ a typical commercial FM station within 2 to 3 tunecxst of the transmitter and enjoy the peace and quiet. Yes, I kept it very simple. Just remove one wire and add another longer one is a slightly different spot.
I believe that one of those wires is a ground. It now works great. SEE PIC-2 After 1 finding a vacant frequency in my area and 2 computing the antenna length for that Frequency I understand that the length attached to the Belkin is added to the length used for the DiPole to compute total length for the selected frequency.
Some good things are the phase locked loop, good sound, and the 12V input that eliminates the need for batteries. If some one can, please point me to it, I’m attaching some pictures! The following is a theoretical exercise for educational purposes only, and not a definitive solution for boosting the tunecast output power to get better reception.
What is your frequency. Tried adding a couple of photos but it keeps coming up as failed, gelkin as jpeg and png but no good. I’m pretty sure that the boards are different for the Eruo and the US market, as we most likely doesn’t have the same laws regualting what you can and cannot do with FM transmitters, so most likely what can be done with the US model cant be used with one you get “over here”. Older gray colored versions of the Tunecast lose their memory settings and reset to If you want to decrease the range, the simplest solution would be a potentiometer with one end connected to the output and the other connected to ground.
Lot’s of nice and interesting info, in this topic and in the whole forum Seems to tunrcast working well so far. This is like getting a basic economy car and modding it to try and make it work like a corvette!! I tried out Delicious again Pt.

If not, post more and I will try to help. Any help would be great If you’re already broadcasting at a range of about ft, what are you shooting for? The newer white ones are fixed. As I brlkin, you need to be at the exact center, because as the signal travels down the outside of each half, if they don’t meet at the center, they fight each other a bit, and can reduce range. The car adapter is just feeding 12v into the tunecast. If you meant the inside end of the attenuator, than I did nothing to that side.
I can only get 50 feet with either device. Thx I’m trying to figure it out but I’m not sure and I wanna be before I do this. 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 With this modification I’m now getting an additional ‘ to the broadcast area for a total of about a ‘ radius.
Note that this step cannot be undone. I get about five to ten feet around the transmitter. Has anyone ever built that RF amp for the Tunecast?
You must log in or sign up to reply here. The marker reads I am getting at least ft, with thh tunecast in the basement and me outside.
BUT then again, I haven’t tested it yet. Yet to do any mods as other projects are more urgent. Im looking to get around 1 kilometer so my friend can tune to my internet station,he doesnt have internet.

I soldered a thin wire to the “inside” end the one not near the edge of the attenuator rather than shorting it, and it worked for me. What I did if any one wants to know I used a good soldering iron, and some VERY thin gold wire did at work under a microscope and just made a shunt around the Inductor that you ripped out ripped up. 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.
Q1 – what kind of of coax? Two different tutorials on modding the Tunecast II transmitter by adding a more effective Antenna. I’m not sure if you even need the coax – I made what I “think” is a single wire dipole – I cut the wire to half or quarter wave length 57″, if I rememberthen ran a wire to the exact middle of the wire and soldered it, then ran that wire to the correct point before the attenuator on the Belkin.
Q2 – solder the center wire the braid or both?
I’m using 52 inches of wire for the antenna, a single strand of the CAT5 cable. Other then that, it’s a pretty nice mod. Don’t use one rated for12V because there is an increase in voltage when not fully loaded which might exceed the rating of the 5V regulator.
