Hi again Dimitrios
 
Further more if you dig out those = old disgarded PMR RX xtals and look you may be lucky like I think third ove= r tone in the range of 45.312 to 45.984mHz made to oscillate on fundem= ental at 15mhz frequencies. They will not be exactly a third of the frequen= cy before the SA's say so but allow a 1kc/s / 32. Vincent has the following= :-
 
45.3333MHz HC50/U wire end, 3rd O/T, Ser Res, Std Freq Stab= ... =A34-25/unit
45.90MHz HC49= /U wire end, 3rd O/T, Ser Res, Std Freq Stab ... =A34-25/unit
 
I was lucky to find some in the junk box for the o= ld 501/4 so never chuck xtals away they laid in my box for nearly 40 years.= ....hee.
=  
The new band is = difficult because any thing below 8megs (div by 16 ) are like hens teeth. <= /font>
 
Thanks for flaging this u= p real ham radio not your ready rolled ham radio well done!!

Subject: LF: 47= 5kHz crystal

Hello LF/MF group,

I though this= may be of interest to those what would like to build the
simplest trans= mitter possible for MF.

I found these cheap crystals on eBay:
http://www.ebay.com.au/itm/2-PCS-15= 200-KHz-HC-49-U-X-TAL-Bargain-Pack-HC49U-/320828846717?pt=3DUK_BOI_Electric= al_Components_Supplies_ET&hash=3Ditem4ab2e3b27d

They are 152= 00 kHz which can be conveniently used with a 74HC4060 to
make an oscilla= tor, then connect to the divide_by_32 line for a nice,
stable 475 kHz si= gnal. You can then drive a class-E FET PA for any
kind of power you like= .

73, Dimitris VK1SV
