DIY KIT WITH ENCLOSURE - QRM eliminator- local noise reduction for radio

Description

An
offer
of
DIY KIT for
QRM eliminator for radio amateurs. Realization of famous X-phaser circuit with high quality elements: original J310 FETs, Schrack relays,
FR-4 PCB with solder mask
etc.
The X-phaser circuit is o
ptimized for 0,5 Mhz to
5
0 MHz range (FT50-43 core used).
It has RF-VOX (RF sensing and switching to "transmit" state).
I have tested RF-VOX with up to 100W TX power and it works fine. The circuit has overvoltage protection but if possible I recommend using PTT (ground during transmition).
Supply voltage should be 12-14V.
There is an option for changing optimal frequency range. In exchange for FT50-43 core I can provide FT50-77 which gives optimized range of 0,5 to 30 MHz.
K
it contains:
- steel
case
with laser made printing;
- all electronic components;
- all mechanical components, knobs, etc.
- all internal wires – CuAg 0,7mm for signal connections, magnet (enameled) wire 0,3mm for transformer winding
- all sockets (antennas, power, PTT),  antennas sockets are SO-239) type.
The kit requires some technical skills and using basic tools. Main skill required is soldering.
Built time is about
3
hours.
After purchase I will provide schematic and assembly instruction in electronic format.

I guarantee fast shipment in
registered letter
via Post.
This is cheapest and reliable method of delivery, although sometimes very slow. Each packet is registered with possibility of tracking.
For other methods of shipments please contact me.
If you have any questions don't bother to ask.
