I just installed a new to me microKeyer II. Trying to follow the setup instructions in the manual, I connected a mono cable (RCA plugs) between Amp Key 1 on the O2 and PTT IN on the mK2. When the O2
Sounds like an RFI problem to me. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com On 12/5/2013 5:43 PM, Rod Greene wrote: I just installed a new to me microKeyer II. Trying to follo
Yea...back the power on the rig down to nothing, and see what happens! ....Dave Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com On 12/5/2013 5:43 PM, Rod Greene wrote: I just instal
Golly, Rod... I am no expert... but I will take a stab at it. Are you sure you have the amp cable routed correctly? My "intuition" (i.e. my gut) says you might consider routing the amp key line from
Unless the amp is QSK capable or he sets the OII to behave as semi QSK, he'll almost certainly suffer hot switching of the T/R relay. Very bad. Kim N5OP "People that make music together cannot be ene
Why would there be hot switching if the Orion is keying the amp? _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo
Depends on how it's set up, but a long delay between keying and application of RF drive, along with a delay between the cessation of RF drive and unkeying the amp is needed to give the typical open-f
Kim, you might be right - Rod's qrz page indicates a 1960's amplifier. _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/li
I am assuming he is not running it QSK... not with a single amp key line. Or am I corn-fused...? -- K8JHR -- _______________________________________________ TenTec mailing list TenTec@contesting.com
There are some QSK systems fast enough to run with a single line if the drive is delayed by a few ms; the Ameritron QSK5 PIN diode switch in my AL-1200 is one. But it does have a minimum time between
In most cases with a non-QSK amp some form of delay system should be employed. This system provides a delay at initiation of transmit such that amp relays close and settle before RF is applied. Then
What other connections are there between the microkeyer II and the O2? The PTT IN is an input FROM the Orion TO the microkeyer. I doubt that this could be the root cause of the problem. Ted W4NZ I ju
The Orion brings up the amp key line 15 msec before transmit comes on. The real test is lower the power output to minimum. If this fixes it then RFI is the problem. Carl Moreschi N4PY 58 Hogwood Rd L
Yes quite true on the delay on transmit being about 15 ms. But what about delay on transition back to receive? I usually find that most radios have or offer some delay on transmit but fall short on t
OK guys, it's time to take the hammer and hit the nail on its head: The BTI LTK 2000 amp is a very hefty amp with a single 3-1000z triode. Although it is a 1960s amp, it does have a 12vdc T/R relay.
"And that's all I have to say about that." Oops... made one mistake. I do have more to say: The Winkeyer II has a built in Winkey (K1EL), which can be keyed by a software (i.e. N1MM), or an external
3rd time's the charm. One point was probably not clear. I explained the Orion's two types of time sequencing delays. What I forgot to say is that it does not really matter when using the MicroKeyer.
Thanks guys! This is all excellent information. After I had posted my question yesterday I went back to the house and settled in for the evening, so I hadn't read any of these messages. Joe solved my
