If they sold it for the asling price, that's ridiculous. £35
would be about right for £15 worth of parts and ½-hour build
time.

Hi Stretchyman. Yes I've seen your gear [emoji106]
I am a bit curious how this performs, its claiming 100% mod and
the frequency response I doubt is that high. I've copied the
specs from his listing below:
Specifications
Medium Wave + Top Band 160M
Frequency Range (Broadcast): 530 to 1800 KHz
Frequency Range (Top Band 160m): 1800 KHz to 2MHz
Frequency Range (programmable): in 10 KHz steps (US Mode), and
in 9 KHz steps (EU Mode)
Frequency Selection: 8 way DIP switch
Frequency Stability 30ppm
Fundamental Crystal Frequency:
10.240 MHz (US Mode) for 10 KHz channels
9.216 MHz (EU mode) for 9 KHz channels
Modulation Type: Amplitude Modulation (AM)
Maximum Modulation Level: 100%
Power RF Output: 50W
Audio Response: 10 Hz to 10 / 25 KHz
Audio Input Sensitivity: (min) 100 mv RMS for 100% modulation
No mention of the input voltage, and the power output is
certainly going to be the PEP and not RMS. Also why no
modulation screen shot or trapezoid which is super easy to show.
The kit must detail about the LPF construction for your choice
of operating frequency, also is the first 2 caps and toroidal
are part of a Class E network?? It's all a bit vague.

This is the same ebay seller that sold the dodgy 15w NRG fm
transmitter kit to radio brian that had tons of problems from
his post on necks.
I can't see this am transmitter being upto much if he was
selling other kits that didn't work, i'm sure brian said the
ebay ads disapeared after he contacted them.

Found this today, think it’s priced reasonably for a fully built
board

I guess it’s best to give anything this seller has up for sale
a good swerve.

That’s good to know, so it’s probably best to give anything this
