Re: Kenwood THD7E Problem with PC connection.

Hi Paul, A second shot in the dark: I recall that a few years ago new SW was released that had to overcome delays in serial communication due to Windows XP (and 2000?). Basically you had to start the SW, do a 'write to radio', turn OFF radio, turn ON radio, and then the actual writing/reading starts. But: that was to overcome an "communication error", not "radio invalid". Nevertheless I wanted to mention this. Did you try with older SW versions or running on older PC's/OS's ? You could also try other SW, I used LINK7 in the past as well. Henk, PA3GUO (owns also the 'old' THD7) =========================================================== Hi Kenneth, I tried all ways, TNC on and off etc etc, the comms starts ok but reports "The radio is invalid" every time? I hate programing up the radio via the front controls!

I thought I would fire up my THD7E and the arrow to work some sats mobile and tried to program the required frequencys in with the PC lead and software. PC and lead are ok as I can talk to the internal modem no problem. However when trying to use the Kenwood THD7(G) software version 1.10 it returns the fault of "The Radio Is Invalid" I tried the newer version of software with the same result "The Radio Is Invalid" I'm sure my radio is the older THD7 and has worked to upload/download without problem before. TASCO Radio Modem AX.25 Level 2 Version 2.0 Release 08/18/98 2Chip ver 1.00 This is the info the modem outputs in TNC mode. Can anybody give me any pointers to what's causing this or do I need to talk to Kenwood? 73 Paul Luggar M0SCI Website WWW.M0SCI.CO.UK Amsat-UK Member 6484 www.m0sci.co.uk/forum Devon and Cornwalls Amateur Radio Message Board _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Yaesu G5500 rotor parts
by Ken Swaggart 13 Jun '07

13 Jun '07

I've removed my G5500 AZ/EL rotor to replace the elevation pot (part no. Q9000408 - used for both the Az and El rotors). Got the part number from Yaesu tech support, then went to place an order and found out they are obsolete - no longer carried! So... anyone have a replacement part number / alternate source for the pots before I try working my way through the Yaesu voice mail system. Also, the elevation bearing retainer rings (S8000208) as out of stock - 4 to 6 weeks to get them from Japan. FYI - I've got some pictures of my last G5500 rotor repair in 2005 posted at: http://webpages.charter.net/k.swaggart/W7KKE/rotor/rotor.html The 2005 elevation repair / bearing replacement held up pretty good - just a bit of rust on the retainer ring and a couple of the bearings. 73, Ken, W7KKE

AO51 & Kids Day using a TS2000
by Henk, PA3GUO 13 Jun '07

13 Jun '07

All, During Kids Day AO51 will have the uplink at 145.880. With my TS2000 I work AO51 always using memory channels. So for Kids Day a new set needed to be programmed. If you have a TS2000 as well, you can use MCP2000 to read/write memory channels using your PC. Do a FILE / SAVE and insert in that file the following new channels: 015200435312000401010800000000600000000AO51a 115200145876000401010800000000600000000AO51a 015300435309000401010800000000600000000AO51b 115300145877000401010800000000600000000AO51b 015400435306000401010800000000600000000AO51c 115400145878000401010800000000600000000AO51c 015500435303000401010800000000600000000AO51d 115500145879000401010800000000600000000AO51d 015600435300000401010800000000600000000AO51e 115600145880000401010800000000600000000AO51e 015700435297000401010800000000600000000AO51f 115700145881000401010800000000600000000AO51f 015800435294000401010800000000600000000AO51g 115800145882000401010800000000600000000AO51g 015900435291000401010800000000600000000AO51h 115900145883000401010800000000600000000AO51h 016000435288000401010800000000600000000AO51i 116000145884000401010800000000600000000AO51i Just make sure you did not use channels 152-160 yet.

looking for DX on AO-7
by w7lrd＠comcast.net 13 Jun '07

13 Jun '07

Hello On some AO7 passes I can "see" a piece of northern Europe and most of UA0 and northern JA from Seattle (CN87). I am looking for a chance to try to "stretch" the foot print just enough. I did a lot of this with RS-15. It can be a bit of a challange, but that's what this is all about. -- 73 Bob W7LRD AMSAT member 28498 Seattle

Yaesu FT-817ND as a satellite 9600 receiver
by Douglas Quagliana 13 Jun '07

13 Jun '07

Has anyone ever tried a Yeasu FT-817ND as a satellite 9600 baud receiver? For example, taking the "9600" audio from the 817 and feeding it to a TNC or a soundcard modem? If so, how did it perform? Douglas KA2UPW/5

Re: Full band transverters for satellite operations?
by Alan P. Biddle 12 Jun '07

12 Jun '07

The 28-30 MHz is rather arbitrary, as most rigs do not transmit out of the ham bands without some sort of modification. I am sure we will hear from the FlexRadio contingent, but I doubt there is any problem in general RX/TX coverage, unless the PA block is so limited. Certain the RX should not be a problem.

Everyones Best wishes
by Steve Raas 12 Jun '07

12 Jun '07

I have to admit I am glad to see the amount of support for people trying to get me to keep things up and running here. However as I see it it's a chance to stream line the station into a portable set up, all be it FM only.. and work the birds in that manor. My very 1st love is VHF contesting.. and as much as I tried to pull off a semi-operable station that could pull double duty (sats as well) it just isn't possible here. There is nothing more frustrating than not being able to point your antennas in a certain direction due to a house in the way or put them up at a reasonable height above the houses ( Tower ) However.. Like I stated before being QRV on the sats does not mean I must have the latest and greatest. I can easily pull it off with an arrow/HT or mobile radio.. and in addition its portable!! In addition as far as the VHF terrestrial operations go.. I will actively look for a group/club that can fill this portion of my operating likes. I will also add its not about winning or loosing with the home owner's assn.. I can win that with 1, 4 minute phone call.. it is however a matter of not being able to enjoy what I had built to its optimal possibilities.. and in my mind.. that is a waste of my hard earned dollar. For fractions of what I put into the previous station I can have a very capable station that I can take with me anywhere.. and operate. I do thank all of you for your good intentions and suggestions .. but this is the direction I want to go to for now. Again Thank You all :-) N2JDQ Steven J.
