I was thinking of calibrating ic-910h so the sensitivity isnt so low but i did not have all the SSG's and whatnot so i shelved that idea. But now i just remembered that i had an IF tap installed so i calibrated for IF gain and now i actually have a decent signal strength(?) and there is no longer a lot of HF signals coming through lol (IF frequency is 10.85).

trying to get g-5500 to communicate with kr-600 but the rotor only goes one way. to make things complicated kr-600 uses terminal 2-7 and 7 is connected to 3 somehow? while g-5500 have separate circuits for terminals 1-3 and 4-6. why cant it just be number x go to number x???  also the socket on kr-500 was switched out for a mil standard socket so the 7 pin rotator plug i ordered didnt fit. had to order a new socket. thats the price for using equipment made and used by old dead radio amateurs i guess.

Reading this i am glad i just had to get 1 exam for everything all at once. Top US ham grade better than generic class Norway ham.

I ground everything. ground coax before it enters house. ground all radios. edit: and remove animals from your devices.

yummycheese posted:nice. I got a gen 1 sdrplay free from a friend and it is so much more capable than a rtl-sdr that its hard to even comprehend. i ordered rtl-sdr v4 and i hope it is an improvement over v3. but sdrplay is way better across the board, agree.

Achmed Jones posted:you probably want to read up a bit more on it. the answer is because it's not like any other device. i don't mean it's magic and special, just that: dang, all the poorly (minimum usable product) coded projects by various ham people to decode various things must be updated :/

Progressive JPEG posted:I once had a sweet ground system consisting of three ground rods spanning two sides of the house, with the rods bonded to each other with a solid copper strap that itself was slightly buried. The circuit breaker panel and water service pipe were connected to this. Antennas were grounded against this system at a wall panel where the feed lines went into the house. So everything was tied together into a single overkill system. I have been looking for a while for a metal box that i could centralize all ground and plug connections. I am looking for something a little bigger since i want to install filters etc. Not having to grovel on the ground outside in -15 celsius under the porch trying to put ground cables and switch out coax plugs and cables would be lovely.

any way it can be offline or running own server? i dabble in sambandstjenesten so i try to keep everything functional offline.

Built a cubical quad yagi yesterday. should have used thinner copper wire then it would have been easier to make a rectangle out of it. i dont know the science behind it but a common mode choke 1:1 balun made swr better.   edit: ITS TAPE! edit2: drilling by hand makes it difficult to have a true straight through alignment for the wooden garden sticks. had to stick pieces of bamboo to adjust the sticks.

BONESAWWWWWW posted:Antennas are basically magic to me. I've never heard of a cubical quad before. Looks great! What's the use case? Or is it just for fun? its just like a yagi but teoretically it would perform a little better.  The antenna i made is for 2 meter vhf band. Tested it with winlink packet and it worked great. It is relatively easy to switch between horizontal and vertical polarization by just moving the feed point from the vertical stick to the horizontal stick. or maybe i can make some complicated dual feed setup for remote switching idk. something like that is probably invented in like 1910, like almost all other radio tech lol. edit: at higher frequencies you can buy antennas like that but it is a circle instead. here is a high weed thought. magnetic loops. array stacked. O_O Someone make the science right now!

Its difficult to find crossover plate with u shaped fasteners or something in norway. It looks like vertikal to horizontal antenna mounting products died when people just use internet and not yagi antennas :/ or i just dont know what kind of norwegian words we use for such things.

I have set up rotator for satellite use and tested it. It worked but i discovered i need to use other type of clamps for my yagi antenna (square boom). and i put the antennas the wrong way so when i want more elevation it stops. classic noob mistakes. also need to consider how to put the cables for the rotator so that it can rotate 360 degrees freely. I am happy i put it 1.5 meters over ground so it is easy to test and fix things.

I am going to try greencube today and see what happens. Hope i dont burn up a hole in the satellite because of too much watt.
