thanks for your reply
range is 10 meter
i already have two crystals, and i don't want to buy others
You will probably receive no help here for a transmitter broadcasting on 20.000 MHz. It is already in use (in USA and elsewhere for time code signals) and we don't want to listen to you interfering.
Change your plans and use a band which is legal for short range communication. We don't care if you only have two crystals.

I do not live in the USA
why no help for transmitter!?
the radio :
from am (530Khz-1.6Mhz)
:
20Mhz
27Mhz
40...
:
:
to fm (88Mhz-108Mhz)
are the 20Mhz is not legal wave??
thank u for reply
No, it's almost certainly illegal.Originally Posted by 16mofed84

In the March 2001 QST Magazine is and article for the "Warbler" transceiver. It is a fixed frequency unit using 3.579Mhz colorburst crystals for its RF filter and operating frequency. Its RF pass band is based on the filter. There is no tuning for input frequency. This unit is designed to use standard crystals that happen to fall within international ham bands.
The same concept could be used to create a single frequency transceiver at almost any frequency.
