Re: Howes DRX20 receiver
I think that you mean the DXR20 receiver.
The "15" on the module suggests to me that it is the BM15 module which had a range of 17 to 23 MHz. I think that you adjust the coil so that the receiver tunes over the desired range. Your best source of information is the GQRP club. See http://www.gqrp.com/howes.htm Google will help you find the review of the DXR20 in the May 1995 issue of Radio Communication. 73 John |
