I have got used to the idea of buying factory built radios, and factory packed beam antenna kits. I don't think I'll ever get used to the notion of buying a factory made dipole or other wire antenna.
With respect to the Cebik article: I agree that this is excellent information. However there is not much discussion about feedline current balance, and the effect of the ground being much closer to o
This is the first I've heard of anyone installing cooling fans in the Omni 6. Actually, this wasn't an uncommon topic a few years back. Personally, I found that my PBT settings were shifted dramatica
A vertical dipole with the feedline coming straight off of the side for at least 1/4 wavelength should have a near prefect circle/round pattern. This of course can be impacted by variations in ground
My Paragons don't go down that low. I wanted to try to listen to SAQ on 17.2 kHz and found that my Paragon II only goes down to 99.9 kHz. When KPH was on the air last week, I used the Paragon II to h
Hi Perry, Great Information! Yes I checked out my Paragon II manual, and sure enough there is a control line which causes RX input RF to bypass the first amplifier stage only when in 0.100 - 1.7 MHz.
But, you say you use 1.5 KW to a KW Matchbox? Didn't think they could handle it. Hi Greg, When the Johnson Kilowatt Matchbox was manufactured, the FCC rules for Amateur Radio transmitter power stated
I have some questions for those who have Orion documentation, or know a lot more about the Orion and may be able to confirm or deny a few of my perhaps naive assumptions. Here are my naive assumption
Hi Frank, A friend of mine was having a QRM problem on 160 meters, which he mistook as a problem with the really strong station's signal. I wrote him the following explaination of how most noise blan
For those that do operate CW, again, it won't make any difference. It will make a difference for those who do operate CW, because there are no CW exclusive sub-bands. All those new "Extras" who have
You may not even need to use the relay in the Omni VI to key the amplifier. The TX OUT line on the Omni VI which is used with Ten Tec amplifiers is connected to the open collector of Q11 (on the Cont
With the OMNI RF output set at 100W on a Bird watt meter the FWD meter on the OMNI jumps to 25W, then decays down to 10W over a couple seconds time. What does the Bird watt meter do? Stay at a consta
Hi Dale, I will tell you what I know about Omni VI IF filter possibilities. All Omni VI versions have a 15 kHz BW 2 pole crystal filter as the 1st filter in the 9 MHz IF. This filter is in the receiv
Assuming the QRO amp is QSK capable will this permit the safe use of the RELAY OUT on the OMNI in "semi break-in" mode (i.e: slow QSK). Theres no way I'm going to want to mess with manual PTT in a cw
Hi Barry, You want to use the RMS voltage value to calculate the power using Power equals Voltage squared divided by resistance. However measuring the peak to peak AC voltage with an oscilloscope is
I measure the peak to peak value using my scope. Then power equals E squared divided by R. This is good enough for "government work". This is wrong! Using peak voltage instead of RMS voltage of the p
The HF-2500Dx does not have a TX EN "ready for transmit" output. As such I would have to assume the high speed switching employed in the amp is engineering to handle the exciter power on key up. -- O
