Grids and QSL´s
by David Maciel 21 Jul '10

I have a question maybe silly to many, I have traveled three times in the past two months to the grid EK34 and EK44, take my portable radio equipment, do not work because my GPS was damaged and another time I forget, but I'm sure the position where I was, may be valid if these grids work and send my QSL with the coordinates where you work? no photo of my gps? I have received many cards from American stations QSL writing grid over your home to put the new grid that time. this is valid? can be done? I have also contacted many stations and sent my QSL card with a photo of the coordinates, I think is best, but not always possible, this'm glad because I think that means that the word amateur is a great value. not if I explain.I had no problems for the ARRL accept these cards an American amateur, whatever the same if that makes a Mexican ham? or any other country? thanks for help.

Wouxon KG-UVD1P
by andy thomas 21 Jul '10

21 Jul '10

has anyone any experience of using the Wouxon KG-UVD1P on AO-51 and the FM birds? I have looked at eham etc and it seems to be a single vfo with channel watch on both V and U; I'm not sure if a carrier on the uhf downlink would just switch the vfo to uhf listen and transmit, ie you could never tx on V if the carrier is on U... can someone confirm that it works/does not work with an Arrow, please? But "cheap as chips", and could be quite interesting? 73 de andy G0SFJ

Four Grids from one location
by Lee Ernstrom 21 Jul '10

21 Jul '10

Hi folks, I was wondering if anyone has operated from one point where four grid squares meet. There is a location just a few miles to the west of where I operated portable from yesterday in Idaho where DN31, DN41, DN32, and DN42 meet. The terrain looks a little rugged but in about a week or so I'm going to drive back up there and check it out with my GPS. It looks like the location is off the dirt road about 1/4 mile so there will be a little hiking involved. WA7HQD Lee Ernstrom Syracuse, Utah DN31xb

Portable power source
by Andrew Glasbrenner 21 Jul '10

21 Jul '10

So I'm trying to move away from my big, dumb, heavy sealed lead acid batteries for portable work, at least when I have to lug the gear very far. Has anyone had any experience with something like these: <http://cgi.ebay.com/Portable-12V-li-ion-Rechargeable-Battery-Pack-9800mAh-/…> ? That looks like it's pretty compact, and will run a pair of 817s a good while. Any suggestions for a more domestic source would be appreciated as well. 73, Drew KO4MA

Hi, guys, A group of radio amateurs including BA4TA, BA4TB, BA4RS, BD5RV, BA4RN, BH4REQ, BH4RLO will activate Pingtan Island (AS138) from July 24-30. This operation is going to include all operational satellites that are capable on V/UHF. That will cover HO68, AO51, VO52, SO50 AO27 etc. Callsign will be B4R/5 during IOTA contest and homecall/5 in regular operaion. QSL via homecall. We are looking forward to having you on the birds.

First Satellite QSO
by Rick Tejera 21 Jul '10

21 Jul '10

All, I finally did it, made my first QSO on the birds this afternoon. Worked W6AJP on A051 on the 0100UT 21 July pass from DM33, Thank you for the QSO. I was also worked by WC7V in DM45, again thanks for the QSO, I hope I didn't sound like too much of a rookie :-). QSL's will be in the mail tomorrow. I did hear someone else call me, I think it may have been K6SIP, but before could reply the bird went below my radio horizon and I lost the signal. My station is pretty simple: a Kenwood TH7D handheld using a homebrew dual band yagi from plans by Kent Britain WA5VJB. Simple to build and works like a charm and only $30.00 in parts. I attached a digital voice recorder to the radio and used my Ipod ear buds (A Heil headset is on the short list of things to get next time I'm at HRO :-)). Again thanks for the QSO's and hope to work more of you in the future.

Re: pole mounting Az-El sysetm
by WILLIAMS MICHAEL 20 Jul '10

Scott, This is how I did it. I purchased a 6 in. X 6 in. X 8 ft. treated wood post and put 3 ft. into the ground without concrete. If I move, I can pull the post out and just fill the hole with dirt. The az rotor rests directly on the top of the post. It is held by four 90 degree (6 in.) angle brackets which bolt to the rotor's bottom and then secure to each side of the post. The 5500 was purchased with a separation kit so a 32 in. mast separates the rotors. This puts the horizontal boom and rotor at about 8 ft. If you like this idea, I can send pictures. GL Mike (K9QHO)

pole mounting az-el system
by Scott Townley 20 Jul '10

20 Jul '10

I was planning on pole-mounting an az-el system: > KLM CP yagis (the shorter ones) > TekSharp 1.2m dish with dual-band patch feed > 8' fiberglass boom > G-5500 az-el rotator with mast brackets. The G-5500 can accept a 2-1/2" mast. And the 2m KLM is about 13' long so I need to get it up at least 7' in the air. So I was thinking of using a piece of electrical conduit. Not EMT (the thin-walled stuff), but rather IMC, which is thicker walled (0.095" vs. 0.065") and readily available at home improvement stores. 2" trade size is 2.36" od so it will fit the mast brackets on the rotator fine. There is an even thicker electrical conduit GRC which is 0.146" wall, but at twice the price and a trip to Grainger (not out of the question but not convenient either) I can't help but wonder if that's overkill. The conduit comes 10' long so I'd put 3' in the ground, say a 12"x36" hole, filled with concrete. Maybe filling the conduit with concrete as well. I'd appreciate any comments as to the feasibility of doing this...particularly the conduit size and hole size for concrete fill.
