I bought an Omni V from K8ZT last year that was loaded with filters. The price took that into account. A new ham friend bought a 746 from a qrz listing. It also came with optional filters installed.
A well-connected ham with a strong business management background in the Virgin Islands from whom I bought a Titan amp STRONGLY advised against using Parcel Post to get from him to me in Chicago. Cou

I agree with that. A month ago, I was running my Omni V barefoot on CW on the bottom of 80. A few days later, I got an angry email from a guy who complained that I was QRMing a DX station 1 kHz away.
hook Ah -- you bring up a very interesting defect in the design of the Ten Tec rigs. You can't use a "flat" mic with them, you need to use one that has a "hyped" high end. That's what the Heil mics d
I disagree. DSP is a big plus in the K2, and I'm assuming it. I very much like the DSP in the K2, and it works very well both on CW and SSB. But it is an AUDIO DSP, not an IF DSP. The limitations on
I've never owned a Jupiter, so this is an educated guess. I suspect it is a low-cut for the transmit audio. I would set it by ear listening to your transmit audio and by getting signal reports from s
That VERY Interesting, Adam. Many thanks for posting this. This is the missing piece of the puzzle as to why our radios are built this way! But it is a really poor recommendation, because it requires
This distortion is caused by overdrive somewhere. It could be in the audio card in the computer generating the PSK, it could be overdrive of the mic input of the transmitter, it could be overdrive of
I've recently acquired a used Hercules II, but without a power supply. Two questions. 1) Does anyone have a matching TenTec supply in good condition to sell for its real value (as opposed to its "col
Here's an email I received from the author of Ham Radio Deluxe, an excellent freeware software suite (in addition to its main rig control component, it also includes a wonderful PSK31 program and a n
The name of the game on Field Day is cleanliness of RF output and a bulletproof receiver. IMO, the only good choices are the newer generation Omni's, the Orion, and the Elecraft K2 family. The K2/10
One point I forgot to address. The K2 is not as easy to operate as the Omni or 746 families. The original post correctly noted, for example, that the DSP system scores very poorly for user-friendline
Racked I did just under 1,000 Q's on mine, in about 17 hours. At my home QTH, in the middle of Chicago, I have a moderately high noise level that the K2 Noise Blanker won't touch (the Omni V NB does)
If the VSWR is below 4:1, RG-59 and RG-8X have very little loss below 28 MHz. IMO, the value of open wire line is HIGHLY over-rated. There's an equation (and a graph of it) in the ARRL Handbook and A
I'm not so sure about that, Ken, even though I've read that statement in a bunch of places from folks who considered themselves "authorities." I have an 80/40 dipole up about 45 ft fed by some old (b

Huh? A good manual is one of the most fundamental elements of a successful product. A product is not finished (and should not be shipped) until a GOOD manual for it is part of the package. FWIW, as m
