Duane, I don't know - I've not yet purchased any. If I do I'll let you know! 73, Steve G3TXQ -- Original Message -- From: dw To: Discussion of Ten-Tec Equipment Sent: Saturday, January 27, 2007 9:16
Jim, Unless I'm doing something wrong, this simplification fails as b tends to a. It produces an answer of 83 for a=b so I guess it's the same simplification as the ARRL's log formula. According to J
Jim, Apologies - my mistake. I misread how the "brackets" were grouped :) This is not a simplification. This is exact. It works for all values of a/b. 120*ACOSH(b/a)=120*(2*LN(SQRT(b/a-1)+SQRT(b/a+1)
Jerry, How do I get that? ..... mental aberration and mis-interpretting the "brackets", that's how :) At the risk of extending this thread for far too long .... what would happen if you "parallel con
Merv, I have the same problem with my Omni VI. I can often move the birdies out of band by slight movement of the PBT control. I asked Ten Tec's Service Dept about the problem and this was Don's repl
Kevin, I have a Corsair II purchased new from the UK distributor on 3rd October 1986. The serial number is 580 - 01861 The schematic shows a single component, D13, for the mixer diode quad; its part
Gerald, Not strictly true .... on my Corsair II the "attenuator" switch removes the pre-amp and "replaces" it with a 3dB pad :) Steve G3TXQ Don't know about the Omni V and VI, but the "attenuator" sw
Jerry, I'll repeat that on my Corsair II when the amp is disabled a 3dB Tee attenuator is switched in, so the mixer is never connected directly to the antenna. Looking at the schematic you could beli
Gary, "METER SWITCH In receive mode, the meter will automatically read S units when the METER switch is in any position except IC" I'm pretty sure the reason is that for all the other functions one s
Hi Ron, If you manage to get your hands on some Scout modules, and you're interested in building your own QRP gear, take a look at my web page: http://www.karinya.net/g3txq/cubii/ where you'll see my
Many, many years ago I was involved in the design of a "survivable" military ComSat system that would provide a low bit-rate channel under heavy jamming conditions. We set ourselves the target that i
Hi folks, I have an Omni VI which just developed a severe "warble" on Tx and Rx, but only on 160m. I assumed the problem must be with the 160m crystal (or associated components) on the Xtal Osc - LO
Thanks for the info. One further question: I would have expected that if I made a slight adjustment to the inductor, the frequency would not vary because the loop would keep it locked to the 20MHz re
Did a bit more work on the Omni VI today, and I'm pretty happy with the results. The line carrying the RF output from the Xtal Osc board to the Logic board phase comparator also returns the DC contro
I wonder if anyone has produced a DDS unit to replace the Corsair VFO ? Steve G3TXQ _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.c
That doesn't sound like the Palstar tuner I have. Mine is the "classic" balanced L network using 2 roller inductors linked by a drive belt and with a choke balun on the TX side of the network. But...
Ernie, I believe that's just for casual data mode operation for those who don't want to connect up their computer! Steve G3TXQ _______________________________________________ TenTec mailing list TenT
Ken, I had to make similar measurements on my Omni VI when I had temperature-dependant XTAL OSC instability problems. I found that the best place to measure the control voltage is across R25; you can
Folks, At the risk of stirring up a hornets' nest ...... .... I continue to see claims that the Double Bazooka exhibits a wider VSWR bandwidth than the equivalent thickness half-wave dipole. But I th
