Houston AMSAT Net now on Echolink
by Bruce 22 May '09

22 May '09

The Houston AMSAT Net is now being carried live every week on Echolink in the conference *AMSAT* on Tuesday 8PM Central Time (Wednesday 0100z summers and 0200z winters). If I get word that there is an ARISS contact and the *AMSAT* conference is being used, it will preempt the net. After June 1, 2009, Echolink will be the only method of receiving the live feed. We will no longer feed the live internet feed that we had been doing on SkyScanner Satellite Radio Network. Our podcast and mp3 files will be available as usual after the net is complete. 73...bruce kk5do

Pre Fab Coax sections
by Jim Sanford 22 May '09

22 May '09

All: I'm hoping to get my 2m - 3456 antennas erected this summer. To help, I've decided to throw $$ at the problem & save time thru purchase of coax jumpers to go between antennas ans preamp or switch. I seek recommendations regarding fabricators of tested LMR 600 sections with N-connectors installed. Lengths would range from 7 to 27 feet. Thanks & 73, Jim wb4gcs(a)amsat.org

Re: FT-817 Transmit Inhibit
by Clint Bradford 21 May '09

21 May '09

>> ... Is there a hidden menu option or some other way in software of preventing the radio going into transmit. You can transmit inhibit via the ACC JACK. That 8-pin, mini-DIN jack provides a closure to ground during transmission, ALC, a transmitter- inhibit pin, and “band data” for connection to an external amplifier. Clint Bradford, K6LCS

Flex-5000 as a satellite radio
by Michael Pfeuffer 21 May '09

21 May '09

Hi all, It looks like Flex is adding a VHF/UHF option to their Flex-5000 with us in mind: * Transmit Frequencies: 2m (144-148 MHz) and 70 cm (430-450 MHz) * Receive Frequencies: VHF (132-165 MHz) and UHF (420-465 MHz) * Low noise preamp: 1 dB NF * Frequency stability: ± 0.5 ppm (internal) or external 10 MHz reference * Standard Version: 30 watts on both VHF and UHF * High Power Version: 60 watts on both VHF and UHF (must be factory installed) * All mode support- supports SSB, FM, FM-N, CW and digital modes (ASFK) * Full duplex cross band operation mode - Satellite ready: B and J modes supported * Separate transmit and receive antenna connectors on VHF or UHF for satellite or transverter operation (requires power attenuation). "available late 2009" / price TBD Full details here: http://flex-radio.com/Products.aspx?topic=F5K_upgrades Now, picture that bandscope displaying a HEO passband... --Mike, WQ5C
