[AMRadio] HeathKit VF-1 Viking 2 wiring
Can anyone help me with the wiring mods needed to use a HeathKit VF-1 VFO with my Viking 2 transmitter? The VFO came to me wired for a Globe Scout. I need to know what the wiring is for it to be powered by the Viking. Also the VF-1 has a plug for a crystal socket, can I change it to a PL-259 to connect to the VFO connection on the Viking which is a SO-239. 73, Ron http://radioheaven.homestead.com/AMstation.html __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
Re: [AMRadio] HeathKit VF-1 Viking 2 wiring
Ron, Unless someone has done some rewiring, it should be fairly straightforward to use the VF-1 with the Viking II. The VF-1 requires 6.3 VAC for filaments and 250-350 VDC @ 15-20 ma for HV. The Viking II has 6.3 VAC and 300 VDC so the power supply for the VF-1 is no problem. On the VF-1 socket in the back Pin 1 is ground; on the Viking II (VII) Pins 1, 2,4,and 6 are grouind. Wire VF-1 Pin1 to VII Pin 1 for ground. Wire VF-1 Pin 4 to VII Pin 3 for B+ Wire VF-1 Pin 2 to VII Pin 7 for filament. On the VII, Pin 8 is a connection to the internal keying circuit. Wire center of plug for the Key Jack on back of VF-1 to VII Pin 8. Suggest using a shielded wire. I am using a PL-259 to connect the output of the VF-1 to the VII without problems. Hope this helps. 73 Mac WQ8U Hillsborough, NC Ron Lawrence kc4yoy [EMAIL PROTECTED] wrote: Can anyone help me with the wiring mods needed to use a HeathKit VF-1 VFO with my Viking 2 transmitter?

Hi Ron, Yes, you can put a PL-259 on the coax from the VFO. Pinout for 8 prong octal socket on the Viking II: 1, 2, 4 6: Ground 3: B+ 300VDC 5: NC 7: 6.3VAC Heater 8: Cathode of first oscillator V6. (provides cathode keying) Heath VF-1 cable color code and original connections: 1:Shield: (Ground) 4:Red: B+ 8:Green: Cathode of 6AU6 (Cathode keying line) 2:Yellow: 6.3VAC Heater On your original VF-1 octal plug, pins 6 and 7 may be connected together. This connecton MUST BE REMOVED or you will short the Viking II filament voltage to ground. 73 and have fun. By the way, did you get the pix I sent the other night?
