Just remember, the injection cable must be a low capacity cable, I believe Drake used a 91 ohm low capacity cable; might want to check the experts on this one. If you have good soldering skills, you can make your own. Or if you prefer, premade cables can be obtained at the WB4HFN website and elsewhere.

The INJ, (and CAR OSC in the C-Line, cables used a foam inner dielectric and phono connectors with a white insulation. This cable measures 60 pF total capacity. All other cables used the standard for the day clear polyethelene inner dielectric and phenolic (brown) insulated phono connectors and measure ~100 pF. Original Drake INJ and CAR OSC Cables = 19 pF/ft = .160" o.d. (foam poly) RG-62 = 93R = 13.5 pF/ft = 0.240" o.d. RG-59 = 75R = 14.8 pF/ft = 0.242" o.d. RG-6 = 75R = 16.2 pF/ft = 0.270" o.d. RG-174= 50R = 30.8 pF/ft = 0.110" o.d. Mic Cable (Belden 8410) = Hi-Z = 33 pf/ft = 0.160" o.d. (foam poly) Mic Cable (Belden 8421) = Hi-Z = 16 pf/ft = 0.180" o.d. (foam poly) R/S Audio Patch Cable = 28 pF/ft = 0.165" o.d. (poly) The best choice is the Belden 8421 Audio cable from their "Brilliance" line. It looks just like the other cables, and is very flexible. The RG-62 is OK, but it is 50% larger and far less flexible. RG-62 is also prone to shorting if bent over too small a radius, and is susceptible to heat damage when soldering connectors. The best "feature" of RG-62 is that it is often FREE, since there have been many miles of it pulled out of old computer networks. Belden 8421 is available by the foot from ACK Electronics in Atlanta. Other distributors have it as well, although many require purchase of a full spool. N7IOH, another list member, had some at one time that he was selling by the foot. The only pertinent factor is the total capacity. Impedance and "loss" are not important. Any _reasonably low capacity_ coax will work if the units are cabled together for the adjustment of the INJ trimmers. The cable type ONLY affects the LEVEL of the PreMix signal, (5.645 MHz ABOVE the transmit/receive frequency,) and a small DC control voltage between the two. If the shunt capacity is too high, insufficient LO level for the first mixer will reduce the sensitivity of the receiver and the output power of the transmitter. Some of the "commercial" cable mfrs use RG-59A, but it's a little larger and also prone to shorting if bent over too tight a radius. The ANT lead to the receiver is too short to matter, but you want good shield integrity, which usually eliminates R/S cables. The best connectors I've found are the Switchcraft 3502 plugs, available from just about anyone, Digikey, Mouser, Allied, Newark and just about any reputable parts place. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs <www.k4oah.com> Woody wrote: > /Gentlemen, I have a R4B & T4XB combo that I have had for many years and have > never used except > for the R4B.

IF your AC-4 power supply for the T4X-B has NOT been rebuilt, that is something I really recommend. Most of those are very old now and need some TLC. If you are skilled at electronics and especially power supplys and HV...you can use the Heathkit shop kit to do this yourself. IF you are not I would have it done by a experienced Drake guy. 73, Lee Lee Simmonds Summit DCS LLC ? 260-799-4077 Office 260-403-6936 Cell -----Original Message----- From: Woody <[email protected]> To: Drakelist <[email protected]> Sent: Mon, Aug 1, 2011 12:11 pm Subject: [Drakelist] R4B & T4XB hook up question Gentlemen, I have a R4B & T4XB combo that I have had for many years and have never used except for the R4B.
