Question:

Hi, got this all wired up, soldered together, only seem to be getting white noise from it. Tuning does little other than adjust the pitch and noise that the speaker generates. any ideas? cheers, John

Answers:

  • Posted by Michael Lockhart on Monday, 20 April 2015

    Hi John, The radio kit is one of the few kits we sell that is very hard to fault-find with. If any connection is bad or if any component is the wrong value or in the wrong place the result is “doesn’t tune”. It could be a poor connection but there’s no way to narrow down where it is really. You could try reheating all the solder joins. Maybe double check the values on all the little ceramic caps. A 100nF in place of a 10nF could cause problems. Are you running from a battery? If not you should try running from a battery, this particular IC can be very sensitive to “dirty” power supplies. If none of these suggestions work you can connect us via support@kitronik.co.uk.

Question:

Hello, I got this product and put it together, I then connected the battery up and I could here the speaker making noises but nothing like a radio and very quite. I then started to move around the aerial and move the tuner up and down and have the volume on full blast. I am getting no response from the speaker. Can you please help me thanks! Peter

  • Posted by Michael Lockhart on Tuesday, 20 January 2015

    There could be a few issues for this. If you send a picture of the top and bottom of the circuit board, also include a picture of the connection to the speakers to support@kitronik.co.uk then we can try and work out what might be causing the fault.

    1.All the parts are new and if assembled correctly it works. 2.This depends on your address and delivery option but the website can give you a quote at checkout. 3.This does receive standard FM range 88-108MHz I don't know if it will work with an ipad in the way you are asking. 4.This kit is not available pre-assembled.
