I thought I read sometime here...maybe some other reflector or eham, that a fellow contacted the company and caused them to revise their charging unit. They really have to comply and maybe some of th
I am interested in the rack cabinet with rack ears for the 238 if that is what you have. Is it clean without marks on it? These rack cabinets cost around 400 or more new I think. Is that what you hav
That's what I was thinking. Short of putting a recording oscilloscope on the supply leads, I would buy their "official supply" and run it that way after it's fixed. Then you will have sorted out the
Then I think you need to adjust the master oscillator which is the 20MHz osc trimmer on the logic board. That seems pretty far off for it but maybe. The band oscillators wouldn't all be all off 2K an
Do you turn off the left hand column..."Favorites...etc."? Then you will get the links at the top left of the page. Chuck, KE9UW -- Original message -- manual window (search plus some links) on virtu
I've had this happen when too much sunlight falls on the TV ir window. I figured the ir in the sunlight overloaded the input sensor. Chuck, KE9UW -- Original message -- 32" TV and my Mintek DVD playe
I emailed the company and requested the price (950). The site doesn't have any pictures of the guts, etc. but the thing really looks good and the price seems to be in line with low volume, special hi
I mentioned this on a reflector which W8JI saw a few years ago...about the efficiency of the L as opposed to the T. He emailed me that, depending on how much of what element the L required to match,
I'm not sure I would call it an "apparent" match. It's just that a T network is two L networks back to back. You can transform up to some impedance and then down to what you are trying to match. How
If these are the diodes that switch in and out the input band pass filters, you are better off with pin diodes which switch much slower than 4148s. The reason is so that strong incoming rf does not s
I have the MM=3. If it is the same...pushing *C738 on the keyboard sets it to Curtis type A and *C739 sets it to Curtis B. Chuck, KE9UW -- Original message -- the AEA MM-2 Keyer is "A" or "B" keying.
I know the problem. I lube mine with the contact cleaner on a rag (and wipe the turns). I use one of the Caig products which has a bit of lube in it...like Preservit P5. Radio Shack has some of this
I have had a problem occur when using an loop receiving antenna on the aux receive antenna input when transmitting on the main dipole (with a Yeasu 990). I had to put crossed diodes on the aux input.
I think what is being said is that the carrier null is much more critical with the Inrad 2.8 over the TT 2.4. The 2.8 does not affect the nulling adjustment. It's just that the null adjustment is pro
I have some DB25 to DB25 cables about 20 feet long (all 25 wires inside connected end to end) which I think are shielded...by noticing that the shells are connected together from end to end...I hesit
I have a factory Omni VI+ (1997) and it has the temp controlled oven oscillator. I think the TCXO is the temp compensated oscillator...so no warmup time. My ovenized osc seems to be fairly stable aft
The carrier null is on the TX audio board...that would be page 4-39 in the Omni VI book or 4-25 in the Omni VI+ book. The pots to adjust are R3 and R4 at the input of the opamp U4...the balanced modu
