I'm surprised no local licensed electricians jumped in on this one...Anyways K4SAV is certainly right,there is a rigid conduit riser for physical protection,then it could be either URD direct burial cable or pvc conduit,depending on what the local utility requires.The reason for the one ground rod at the meter socket only, is you should have a 4-wire run to the service panel,2 ungrounded conductors, one insulated grounded conductor(Neutral) and a bare wire Ground.By the way, PSNH requires 2 ground rods at meter socket,8' apart,regardless of NEC. I have driven hundreds of ground rod in the tri-state area (NH-VT-MA),and what I use is a Hilti TE-72 hammer drill with a special "ground rod bit", and the trick is to drive the ground rod at a slight angle,trying to drive it straight down often leads to a cut ground rod,as it will not go over or under a rock,instead trying to go "thru", not good. I'm sure you can rent a hammer drill at a local rental shop along with the ground rod bit,if not, I'm sure the local electrical contracter will come out and drive a couple of ground rods for you at fairly reasonable cost. good luck Neil AE1P p.s. Being an electrician and a Ham does have its benifits, I get a "great" deal on my ground rods : )

Thanks to all who replied; And yes,the only reason I'm mounting it on the mast IS so I can have radials,not getting into particulars,but if I mounted it on a tripod on the peak of the roof ,it would be nearly impossible to get any longer radials(30' & 60'),planning on at LEAST 2 radials per band,starting at about 16' high and tied off about 10' in the air;hopefully more on the higher bands; thus the question of sleeving the mast with a non-conductive material; 73, Neil,KB1KOX

I'm going to be putting up this antenna(5-BTV) this weekend;unfortunately I'm not able to ground mount it as there is no good location and can't mount it on the roof with a tripod either,wouldn't be able to use any radials,what I'm going to do is mount it with 2 - 12" wallbrackets and a 15' piece of 1-1/4 alum. IMC,the antenna will end up about 4 to 5' above roof line, has anyone else done it this way,and if so,was the antenna insulated from the mast with a sleeve?Trying to save some time tuning it up,and the instructions do mention isolating the antenna from a tripod,wondering if a mast driven into the ground a foot or so would give me problems,or maybe help if I cut the mast to a certain multiple?? At least mounting it this way I'll be able to get a bunch of aerial radials up. Any and all thoughts welcome, 73, Neil, KB1KOX

<What are YOU doing to support ham radio? I've got two young children, a wife, a house, 3 aging vehicles and a yard to take care of, and a 65-hour-a-week job. No way you're busier than I am. GET CRACKIN' !!> So true Steve,I'm in the same boat myself ! If its a passion,you'll find time to get on the air,or elmer,or whatever it takes to be involved. This weekend is a perfect example;There is no reason as far as I'm concerned,that anyone who holds a license shouldn't be on the air,and try to get someone who "isn't " licensed involved with field day,and even on the air!!

Thanks Mike for the e-mail,and Thank you Steve for the Technical advice.Thanks to everyone who replied infact. I'm not really looking for perfection,was just trying to get something up for this weekend,and figured if it was easy enough building one loop,why not do 2 and stack them;and was having a hard time finding any info on the phasing harness,still not really clear on that yet,one source says 2 - 50ohm cables with an 75 ohm feed,another says 2-75 ohm with a 50 ohm feed,I guess they would work the same,anyways, I think I'll just go with the one loop for Simplicity, Hi-Hi... 73 all neil, KB1KOX/AG

Ok, thanks Chris & Webster...... Will give the Quad some thought,Though don't you know, I have all the materials for the "Sloops" I do have the 20th ed. Antenna book and Cd,and my guess is I'm looking in the wrong spot,been concentrating on ch.18,VHF-UHF.Where would I find some info and drawings on the Quad, Chris? A trip to the hardware store is still possible,Thanks in advance, 73 KB1KOX/AG

eHam Forums / Elmers / TS790 does supply a mike ?

Now that you mention it,I did have the batteries in it. I've since replaced that mic with a MC-60,which I run without the amp battery! There is a schematic of the MC-80 mic on www.mods.dk if you don't have one.I would think the mic would still work without the batteries,(Just like a d-104) but can't be positive and can't test that for you as mic is gone. Good luck Massimo, 73, Neil

Planning on putting together some of K0FF's 6-meter loops,I would like to "stack 2 of them together",but having a hard time finding some specifics(Did a google search and looked through joe carr's antenna book) Anyways,I believe if I cut 2 pieces of 75 ohm coax at 1/2 wavelength,and stack the loops at 1/2 wavelength,I should be close enough of a match for this weekends VHF contest. But any input from an elmer would be much appreciated,Time is Short and don't want to be way off, Thanks all, 73 KB1KOX/AG

I have had a MC-80 hooked up to one of my TS790's,worked fine.You should have 8V/approx 10 mA on pin 5,hopefully you have a bad mic.Good luck KB1KOX, 73

Make sure your cable is a RS-232C cable and not a Null-Modem cable(pins 2 and 3 swapped) Also Make sure your "port"settings are:1200 baud,7-bit,even parity.(that includes in Device Manager) And make sure to do a Loop-back test with the pin #1(green wire)and pin#2(white wire)twisted together.If that doesn't work,you might have problems with the PK-232. Good Luck,hope this helps, Neil...KB1KOX

WB2WIK Thank you Steve,that post put a grin from ear-to-ear after a rough day of electrical work-I think we're getting the fuses for our disconnects from the same depot!  Neil,KB1KOX

Hello Doug, congrats on passing your Tech exam! Speaking from my own very recent experiance,I have a TS-790,fused on both leads hooked up to an astron rs-35A,(with the "open" lugs on back)and while fishin wires down behind the desk to PS for Acc's,shorted between both posts(OOps!).Blew the 8A fuse in the PS and the 15A fuses in the lines to radio,and undoubtable saved my radio any harm by its being fused!As the saying goes,an ounce of prevention is worth a pound of cure,definately fuse the leads!I would much rather replace $2.00 fuses than an $800.00 Transciever!Good luck! and give a shout on 6.805 when in Swanzey! Neil, KB1KOX
