Re: Request for help with satellite capable old rig ECHO 70 by KLM
by Prof. Arnaldo Coro Antich 20 Jul '12

20 Jul '12

Dear amigos : I am new to this list. My very good friend CO6CBF Hector asked me to make a comeback into the ham satellites world. I found an ECHO 70 KLM transceiver that was in bad shape, but that could be repaired. Now it is receiving , but on transmit the power is only 1 Watt. The receive sensitivity is not great, but enough for Hector to make a two way contact with it... Hector has a very good 70 cms band antenna system that really helped. The 70 cms signal level at the input of the first of two output filters is 10 Watts, measured with professional test instruments, but after the filters there is only 1 Watt. I suggested to Hector that he blew hot air over the ceramic trimmers of the two filters in order to remove humidity ... It worked on one of the filters... now there is good power output on the 435 megaHertz segment , but 432 megaHertz is still at the low power output level. FYI, we are not authorized to operate on the 432 megaHertz segment used by the Oscar 7 AO7 ancient satellite... but do have permission to operate on the 435 megaHertz segment that other satellites use. Any information about the ECHO 70 KLM transceiver that can be found will be most useful, as once the rig is in good working conditions it will be used frequently from my EL83td grid square location in downtown Havana, and possibly by mini dx satellite expeditions to other nearby grid squares too. If the files that contain the information about the ECHO 70 KLM rig are large, please send them to: arnaldo.coro at gmail dot com Thanks in advance for your help and hope to make many new friends in my return to the amateur satellites world after many years of absence * I am from the days of Oscar 7, RS 10 and RS 12 and RS 15 * !!!! 73 and DX Arnie Coro CO2KK

CQ European western coast & South America
by Hector Luis Martinez Sis 20 Jul '12

20 Jul '12

Hello there! This weekend EL92sd will be into the FO-29 footprint with the European western coast. If any station wants to try a contact, please drop me an email directly. There are some opportunities to try long contacts with South America also. If you are into any footprint and want to try, please drop me an email. The Cubans cannot operate on AO-07 mode B, So FO-29 is our only opportunity for long contacts. 73!

KCT Tracker Tuner

I have a Kansas City tracker tuner. Cleaning off the "Stuff not in use shelf". If you have an old computer with an ISA slot or just collecting Satellite relics make a reasonable offer. Original box, manual and the like.

Dear All, I have two units of stuck Yaesu rotators (G-5500 azimuth unit and G-2800) that I use for satellite and terrestrial communications and have been finding it difficult to locate repair services around this region. As I will be heading to Sydney, Australia next month, I wonder if there are such repair services available. If anyone has any info, kindly drop me an e-mail off the list. Sorry for the bandwidth and appreciate any help or pointers given. Thank you. 73, Sion Chow Q. C., 9M2CQC, WQ2C

Teachers Institute July 24 at W1AW
by Mark Spencer 19 Jul '12

19 Jul '12

Hi All, Thanks for your support of the teachers institutes in Sacramento and Dayton last week. Next week is my turn in Newington. For those wanting a contact with W1AW, I will be testing my portable set up for the TI on Sunday July 22 during the 1741Z pass of AO27 in the League parking lot with call W1AW. After the contact, if you would like a card, send me an e-mail to my address below and I'll take care of it. I'd appreciate it if you could give us some demonstration contacts on Tuesday July 24 during the 1824Z pass of AO27. The TI curriculum is packed full of activities, therefore I can only spare that time for the satellite demonstrations. Thanks, Mark Mark Spencer, WA8SME Education and Technology Program Director ARRL, the national association for Amateur RadioTM 43 Pinelock Dr. Gales Ferry, CT 06335 860-381-5335 860-460-1139 (cell) mspencer(a)arrl.org
