I just found it...it's called the AmpKeyer and it's $39.95 from "The HeathKitShop." If you don't mind performing a very minor mod to your SB-220, the Harbach solution is the best and it's half the co
If I'm following you correctly, you should be able to adjust the relay duration through either 1) the Ext-T/R time delay through the menu on the computer, or 2) the VOX delay adjustment, also on the
Yes, the milage truly does vary! I replaced all BP board diodes with the HP 5082 types as suggested by U. Rhode and had very satisfactory results. Like you, I had to re-bias the diodes in order to p
products. respond Ten-Tec, like most companies, has a customer service and technical support process in place for addressing such issues. If you have a question that cannot be easily answered by som
connect the line out ( to the soundcard iin my case) is a stereo mini phono. Without tearing apart the rig, is the jack really stereo and if so what is the purpose? The Line output is dual-mono in t
I don't have my schematic handy, but start by unplugging Plug 52 on the IF/AF Circuit Board and tie-wrap it out of the way. That's right...the plug just floats in the cabinet. I'm pretty sure its Plu
The better quality power supplies have an extra set of high-impedance "sensing" terminals that are used like a digital voltmeter. On short runs, they are usually strapped together, However, on longe
They ALL are prone to failure. So what? My new FT-1000D failed within two weeks of ownership. My new Kenwood TS-950SD failed within two months of ownership. My new Yaesu FT-2400 failed to power up ou
That's right. In the Omni Six Plus (not, the upgrade...but the real deal), the TX BFO crystal switching scheme is different. The theory is that in CW, the LSB crystal would require less of a frequen
Where the problem becomes apparent is when frequency error far exceeds the least significant display digit. In other words, if the display is meant to indicate an operating frequency down to 10Hz res
Yes, but be aware that the LSB and USB BFO carrier set point will require readjustment and this will no longer track with your narrow filters. I would order a custom INRAD filter with an offset cent
Yes, but the crystals are the same only the alternate sideband crystal is used. This results in less of a required frequency shift in the CW transmit offset. I had modified my Omni Six this way befo
I imagine guys like Carl, N4PY will easily develop some form of software translation table into the software (like he has now), which will allow the GUI software to control one of many different Ten-
I'll second that, including the upgrade to the TCXO. Back in 1997, I replaced both BFO crystals with a set from JAN in Fort Meyers, FL. Only...I was seeking to stabilize the Omni's microchirp proble
I just compared the Orion specs against those posted on the Elecraft web site. If the ARRL lab's test results confirm Ten-Tec's posted specification, the Orion will blow the K2 out of the water in te
I can get my Omni Six down to less than 1-watt, so I'm not sure why yours would be different. The Omni V required a resistor change on an op-amp to reduce the minimum output power to less than ten wa
Hmmm....I had thought IP (e.g. IP2 - IP3) refered to "Intercept Point" as an intermod measuring basis for receive performance, not the transmitter...or is my assumption incorrect? If so, then how is
