@Audioguru how much higher? ok, I'm going to refresh my memory on inductors again tomorrow.
Thank you! I think that might be the problem. I'll buy some other and try it again.
@danadakk I'm pretty sure there are no shorts. I have Fluke 116.
@Audioguru I use 0603 fixed inductor with high Q. But I'm not sure if this is a correct one.
@danadakk - I don't have any connectors, I just soldered everyrhing on the PCB, including antenna (basically, a piece of wire - 1mm thick, not sure if this is correct too...). Thus, my PCB is a lot smaller.
@Audioguru thanks for the explanation. I'd really like to hear *anything* for now. And...
Hi!
I build this FM transmitter using MAX2606 but since I'm still new to electronics, I'm not even sure how to check if it works... :/
Here's the schematic:
1) I'm not sure the schematic is ok. I took it from the web somewhere and slightly changed (well, according to my level of knowledge)...
The idea is to use SPI NAND flash with MCU. MCU provides a clock (1 - 4 MHz).

Found this one - Micron MT29F1G01ABBFDWB 1Gb. It is SPI. But I wonder if it works with 1 or 4 MHz clock.
Hello,
I've never looked at SPI NAND Flash IC's but I'd like to use one now. I've read some datasheets but I have some questions if you don't mind. For example, this Micron Nand Flash memory.
If we take 2Gb one, they say:
Page size:
x8: 2,112 bytes (2,048 + 64 bytes)
x16: 1,056 words (1,024 +...
Yeah, I'm going to finish a book first as RF is a black magic to me at the moment.

I just found out there are chip antennas! Never heard of it.
Yes, that's what I thought too. But now the question is - what is the right way of doing this?...

Or I guess I can just tune the output of the preamp, right?
Yes, this is it. And that's why I ask basically - if I want to have a mic preamp then its should be limited so, that this standard freq deviation would not exceed 75 kHz. What if I need more amplification of the mic input?
Anyway, I should try it and see. But I don't understand this part even...
What I don't really understand is this - suppose I generate a deviation of 3 MHz (not sure the terms are correct). So my loudest sounds create that huge modulation. Would a regular FM tuner produce such sound? I guess not.
The idea is to be able to "hear" both - quiet and loud sounds, which...
