I have just about done every combination of mistakes – leaving a cable disconnected, confusing the cables and trying to listen on 2m and transmit on 440, etc. I did I good one last night.... I was about 2 minutes from flipping the switch and seeing if the digi I just put up worked. I got everything hooked up (supposedly), powered everything up, my adrenaline is pumping, and ............... its not receiving anything. I thought a good test would be to beacon with the D7 and see if it would get digipeated, and it did. I watched the S-meter on the digi radio peak, TNC receive and transmit lights come on, and all appeared fine, except for the fact that it wasn’t receiving anything other than my packets. I stuck my head around the backside of the radio (and it was dark), and I realized I hadn’t connected the antenna coax to the radio. Needless to say I quickly powered everything down. The radio is fine, just gave me a good scare. \n\nI would love to put together a blooper reel of all of the dumb things I get into... Trying to contact Europe and the dog starts doing laps around me, trying to listen to a low audio station and a Harley Davidson flies by, stabbing my face with one of the Arrow elements, slipping in the snow and mud, and the list goes on and on.\n\nOperating outside with the Arrow – you can’t beat it. ;-)\n\n73!\n\nZack\nKD8KSN\n\nFrom: Tom Deeble \nSent: Saturday, January 29, 2011 12:32 AM\nTo: [email protected] ; [email protected] ; [email protected] \nSubject: Re: [amsat-bb] Re: 2 ht vs. 1-duplex ht\n\nZack,\n\nIn the discussion of two vs one - I found a new way of screwing things up today. I was trying to operate via AO-51 this afternoon\nand was never making it into the bird even though I was receiving fine. Turns out I still had the 440 side of the IC-W32A selected\nas the \"main\" radio which makes it the xmit as well. Each time I tried to xmit the radio displayed out of range (found out at the end\nof the pass) So, now I have one more thing to check before the sat comes around! Other than that the W32A with a 440 preamp\nhas been working well for me.\n\nAnother time, when I was running late, I wasn't making it into HO-68. That time it ended up being a disconnected BNC to the 440\nside of the Arrow antenna.\n\nSo it seems that with each new hobby I can find very creative ways of messing things up. Hope you have better luck.\n\n73's\nTom - KA6SIP\n\n\n\n\n\n-----Original Message-----\nFrom: Zachary Beougher <[email protected]>\nTo: amsat-bb <[email protected]>; amsat-bb <[email protected]>\nSent: Thu, Jan 27, 2011 6:02 pm\nSubject: [amsat-bb] Re: 2 ht vs. 1-duplex ht\n\n\nHi Patrick,\n\nYou are the go-to guy for any Kenwood HT questions - have you owned/used all \nof them??? ;-)\n\nThe toggling between VFOs was not as big of an issue for me (like you say, \nsmall price for a full duplex HT), but the receiver seemed weak. I know I \ncommented a few weeks ago about the 8800 having a weak receiver, but I think \nafter using the G71As for so long, I got spoiled with the receiver in it.\n\nThe s-meter is also practically useless on the D7. You have to toggle back \nand forth between bands to see it, and it also never goes above approx. \ns3-s5, on a good pass. It makes it difficult, especially when a bird is \nquiet, to tell if you are on it or not. You need to have keen ears to tell \nwhether you are listening to the carrier or noise.\n\nI didn’t use the D7 for much satellite work before I went back to the G71A \nfor receive, so I probably need to try the full duplex again and give a more \naccurate observation.\n\n73!\n\nZack\nKD8KSN\n\n-----Original Message----- \nFrom: Patrick STODDARD (WD9EWK/VA7EWK)\nSent: Thursday, January 27, 2011 10:24 AM\nTo: [email protected]\nSubject: [amsat-bb] Re: 2 ht vs. 1-duplex ht\n\nZack,\n\n> I have the D7A (full duplex), but I don’t like the receiver sensitivity. \n> I\n> went back to using one THG71 for the down and the D7 for the up.

I have heard things about the D72.\n\nIf someone is looking for a single HT for full-duplex satellite work, I \nwould\nrecommend the D7 despite having to switch VFOs for Doppler adjustments.\nI have the TH-D72A, which works the same way as the TH-D7 regarding\nthe need to jump between the two VFOs to adjust the receiver. It's a small\nnuisance, but a small price to pay for not having to deal with two radios\nwhen working full-duplex on FM satellites. I've picked up a couple of old\nD7s (one appears to be a TH-D7A(G), and the other may be an original\nTH-D7A), that I hope to get new battery packs for and make a couple of\nFM satellite stations when combined with Elk antennas.\n\nYour TH-G71A is a good dual-band HT. Not capable of full-duplex operation,\nbut worked well for me using groups of memory channels for FM satellites.\nThe receiver was pretty good, and some would notice that I changed to a\ndifferent radio from my normal radios when I used that HT.\n\n73!\n\n\n\n\n\nPatrick WD9EWK/VA7EWK\nhttp://www.wd9ewk.net/\n\n_______________________________________________\nSent via [email protected].
