"Karl Henrik Laache" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- I've got a NIB FS-4 with all the original cables, stickers etc. The inj. cable is an unmarked grey cable, probably an audio cable with a RCA/phono connector in one end and a solder lug and pin in the other end for connection to a screw and one hole in the crystal holder. The cable is 40 cm long.
The cable is definitively not RG-62 which is advised for the injection cable between the B's and C's. But for all I know you may be able to get a little more RF from the FS-4 to the rcvr or xmtr with the low capacitance cable. The output seems to be a little lower with the FS-4 than with the xtals in the rcvr/xmtr. 73's de LA1CU Karl email: [EMAIL PROTECTED] -----Opprinnelig melding----- Fra: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] På vegne av [EMAIL PROTECTED] Sendt: 23. oktober 2005 22:53 Til: [email protected] Emne: Re: [drakelist] FS4 injection cable [EMAIL PROTECTED] made an utterance to the drakelist gang ---------------------------------------------------------------------- On Sun, 23 Oct 2005 11:30:18 -0400 Garey Barrell <[EMAIL PROTECTED]> wrote: > > Garey Barrell <[EMAIL PROTECTED]> made an utterance to the drakelist gang > ---------------------------------------------------------------------- Could be wrong here, as I am going from memory, but I believe it was RG-62 [93 ohm] cable. > Bob - > > I don't know what Drake originally supplied, but I would guess it was a > piece of (possibly low capacity) microphone cable, which is about half > the capacity of RG-58.
