A quick Google search of "kenwood TR9500 satellites" came up with several citations of hams using that rig successfully on the birds! Clint, K6LCS >> ... Has anyone used a Kenwood TR9500 70cm all mode on the satellites?

Re: G5500 Elevation Rotator Short Circuit?
by Clive Wallis 06 Nov '11

06 Nov '11

Many thanks Tim for your comments. From what you've said it sounds like a faulty motor. In the ones you've repaired have you been able to determine the cause of motor over heating? The problems I've had in the past have always been due to water getting into the units. 73 Clive G3CWV Hitchin, North Hertfordshire, UK On 07/10/2011 18:50, Tim Cunningham wrote: > The common failure of the motor windings is caused by heat which > causes the enamel coated wire to breakdown.

CM86 for one more pass
by Patrick STODDARD (WD9EWK/VA7EWK) 06 Nov '11

06 Nov '11

Hi! Thanks for the QSOs on the last AO27 pass. I did not hear the first 2 minutes of the repeater time, but was able to make 12 contacts in the remaining 5 minutes. Maximum elevation was only 9 degrees, which I saw as the repeater shut off. I am parked on the municipal wharf in Santa Cruz CA (grid CM86xx), and there has been alternating sun and rain in the past hour. I hope to add more to the log on the upcoming AO27 pass around 2118 UTC. Then back up to San Jose. My current location is showing up via APRS at http://aprs.fi/wd9ewk-9 if you'd like to see where I'm hanging out. Most people are walking around or they have their fishing poles out, but I'm doing a different type of 'fishing'. 73! Patrick WD9EWK/VA7EWK - Santa Cruz, California http://www.wd9ewk.net/
