[amsat-bb] Re: Have a TS-2000 and wonder if the Flex or a Icom-9100 , mm
My concerns about the Icom IC-9100 are as follows: When you add HF to a satellite radio you reduce the performance of the satellite bands. What we want for Satellite, EME and DX Terrestrial is a very high performance VHF/UHF receiver, with excellent sensitivity and selectivity. We do not need or want HF in a VHF/UHF DX radio. A good satellite radio should not contain HF. IC-9100 Receiver is only a Double Conversion, (better than the 910 which is a single conversion) IC-9100 TX power output is too high for 2-meter and 70cm for satellite work. 2-meters 100 watts, 70cm 75 watts. Let me explain: For serious Terrestrial DX and EME you need to run more than 100 watts. The output level of the 9100 is too high to match most solid-state and tube amplifiers. Most VHF/UHF amps are designed for 25 or 50 watts maximum input. Since the IC-9100 puts out 100 watts you will eventually forget to set you TX power level and you will destroy your external amplifier. The manufactures of Transceivers and Amplifies need to agree upon a set of standard power level so the amplifiers and transceiver can be properly matched without worrying about destroying the amplifiers. Suggested standards for VHF/UHF bases stations: 6 Meters 50 watts 2 Meters 25 watts 70 cm 25 watts 900 mc 10 watts 1.2 gig10 watts External Preamps: Again for serious DX and satellite work, most use very high quality external pre-amps. The Icom IC-910 required Icom externals pre-amps to compensate for the Single conversion receiver. The Icom preamps did work, however there specifications (Gain 15 dB 2-meters) were not as good as other external third party pre-amplifiers (20-25 db 2-Meters), and they were also limited to 100 watts of RF. It is not known if the Ic-9100 will also required similar Icom external Preamps. Dated Design: The design of the IC-910 was dated when it went into production. The IC-9100 has built-in DSP and a few more bands, however it is still out of date for what the EME/Satellite/DX community needs for this century. IC-9100 Potential Good features: Built in IF-DSP (32 big and 24bid ADC) What do we want for this century for Terrestrial DX, EME and Satellite: Dedicated TX and RX for VHF and UHF. Digital filters (similar to a Ic-756 pro III and newer radios) Band Scope. TX power to match external amplifiers. RX Quad conversion receiver. Full USB computer control (Not RS-232, Not TTL, Interface must include memory channels with the Repeater off-set bit, which is usually omitted by Icom) Satellite mode knob 100% Identical to the Satellite mode knob on the Yaesu 736R. My ideal rig would look like the Icom IC-756 Pro III. It would not contain any HF. The whole RX and TX system including digital filters would be designed just for the following bands: 6 Meters 50 watts 2 Meters 25 watts 70 cm 25 watts 900 mc 10 watts 1.2 gig 10 watts Additional RX/TX filters for satellite reception. It would also have the Satellite Mode switch of the Yaesu 736R, placed in a similar location on the Rig. Multiple Line level audio outputs for computer interfacing to support digital modes such as JT65 and other modes. Just my wish list. wf1f Miles www.marexmg.org --- On Sun, 2/21/10, Jack KZ4USA video...@verizon.net wrote: From: Jack KZ4USA video...@verizon.net Subject: [amsat-bb] Have a TS-2000 and wonder if the Flex or a Icom-9100 would be the next best step for satellite work.

[amsat-bb] AO-51 20Feb2010 2259z Recording
A recording of the AO-51 pass on 20Feb2010 at 2259z is on my webserver: http://www.papays.com/AO-51_20Feb2010_225938z.mp3 This was a very busy pass with ND9M/p in EL07/EL08 and WD9EWK/p in DM22 at the Yuma Hamfest. Many of you are not full duplex and don't know what you sound like on the bird so here's your chance to hear yourself. There are over 30 different callsigns on this recording including: N5AFV, KD4N0Q, WA4HFN, N8RO, WA5KBH, KP4WK, KF4OTG, N5UXT, KB0RZD, ND9M/P, K4YYL, K7NN, KB0RZE, KB8ZGL, N1XED, KJ4PSU, VA3BL, N8MH, ?4NDA/HH, KD8CAO, N2BX, WD9EWK/P KZ4WAT, KB9AVO, KD0HKR, WB1AAT, N0JE, ?OF, ?QYH, VE7CNA, KE7DOV. K8YSE KE7DOV appeared at the end of the pass operating portable from CN76 a rare coastal grid. Although there was a lot of instances of several stations transmitting at the same time, overall the number of successful qso's was good. It is rare when more than 30 stations are heard on a single pass of AO-51. It was a 32 degree elevation, 13 minute horizon to horizon pass for me. AO-51 is a great bird. Those who had a hand in designing and building this satellite can be very proud of their accomplishment. 73, John K8YSE EN91dh ___ Sent via amsat...@amsat.org.

Hello All, Yes, it will be held on Easter weekend...but the event is on a Saturday :) I will be hosting an AMSAT table at the RARSFest in Raleigh, NC on April 3. Would really appreciate some help. Demonstrations are possible, but this depends on how much help you all provide. It's a nice hamfest, and the RARS club is always very hospitable to an AMSAT table and workers. http://rars.org/hamfest/ If you can commit to helping me on April 3, please contact me directly off-list n8mh AT amsat dotorg Thanks! -- Mark L.

[amsat-bb] Re: HO-68 and FO-29 common uplink
Hmmm... Interesting. That means that we all need to check both satellites before using either one, to be sure the orbits and modes are compatible, and avoid the passes that aren't (no matter how tempting). Dual-bird SSB/CW ops may be confusing, but accidentally running high power FM into FO-29 could be far worse. That bird is too delicate and precious to abuse.
