Heres a general bureau QSL question. Has anybody received a card from the Bosnia (E7) bureau recently. I have many cards that are 4 and 5 years old and go to stations who use the bureau but to date I havent received any cards from E7. Just something I noticed (I know the bureau is slow but just curious if anyone else noticed same thing).
The Blacked out comms story was certainly a hoax but the light following them was real. I saw the footage and listened to the conversation in A documentary. You can hear when they ask Houston for the posistion of the boosters. Then an airy silence when they are told they are several thousand miles away. It certainly was handled professionally and Aldrin has since tried to clarify his UFO type statements and say that he thinks it was some kind of reflection, but adds he is not sure because it looked like a hollow cylinder.
OK, so this weekend I will be in the Catskill regions of New York. I'll be operating as a SOTA operator and will be including 6, 2 and 432 weak signal.
My question is:
For those who have not worked many of the grids center of the state of New York which grid squares, or mountain tops would you guys like to work?
Depending on quantity of responses I will be willing to accommodate to give you that grid Square, or SOTA mountaintop. I will be operating HF bands 40m -10m as well. For weak signal work I will have directional antennas for 6, 2, and 432. As usual on all of my outings I will as well be recording my operations. Within a week I will have a video edited and uploaded to YouTube. Hope you all enjoy it.
Hope to hear some requests if interested. If not plans are to hike the highest in the area. We'll be solar powered so I'll be operating just before sunset hoping to catch some Tropo or better.
Spend money on very good antennas. Run 1500 watts out all the time. Use separate specialized receiving antennas.
I bet we will still enjoy Ham radio without all the above. Contacts will just be more valued. But if you can afford all the above, go for it and add even more pleasure. I refuse to worry about the future.
If your analyzer doesn't give you the sign of the reactance then it isn't as useful, but with some work you may be able to figure it out. Unfortunately, some of the techniques that might work when connected directly to the antenna can trip you up when you try to measure the antenna through a length of feedline.
Perhaps the simplest is, if the impedance reads, say, 80 +/-j 100 ohms, would be to calculate a capacitor value with approximately 100 ohms of reactance and stick it in series with the load. If the reactance doubles, it was capacitive. If it drops to near zero, it was inductive.
Often a more convenient method is to translate the impedance into parallel notation and do the same thing, using a T connector on the analyzer and connecting the test reactance across the open end. You don't even need a precise capacitor / inductor value: by adding any reasonable capacitor and watching the change in measured reactance you should be able to tell whether the reactance magnitude increased or decreased.
It's much easier, of course, when the analyzer can resolve the sign of the reactance.
I see now what you're up against. Are those N connectors at the tops of the cavities? If so, perhaps it would work to put an N tee on it with a 50 ohm load on one side and an antenna analyzer that incorporates a VNA on the other. For example, I have the Rig Expert AA-230 ZOOM analyzer and it will measure return loss. It may not hurt just to check one cavity to see if you get reasonable readings.
The Sinclair brochure doesn't spec return loss but it does note that the maximum input VSWR is 1.5:1, which works out to a return loss of 14 dB. Obviously, the higher that number is (greater than zero), the better.
I just got this power supply (supposed to be working) I put my meter on it 0vdc, checked the fuse it was good, transformer hums I took the case off and everything and it looks good to me no shorts on the board. I need to know where to start getting this going again.
