Sure! I´ve worked very low passes (5º and less) using a TH-F7E and a CJU antenna (even a dual band whip). Lots of transatlantic QSOs from mobile. My F7E is quite sensitive, but the bandwith is somewhat wide for SSB: http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20via%20FO29%20desde%20movil.html http://eb4dka.laserenadigital.com/Amateur%20Satellite%20Articles/FO29_MOBILE.pdf http://eb4dka.laserenadigital.com/Imagenes/EB4DKA_FO-29_MOBILE1.jpg I even used it for the AO-40 downlink in my mobile setup (glory days!!!): http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_Kenwood%20THF7%20recibiendo%20el%20AO40.html 73 and happy new year!

[amsat-bb] Re: Active FM Sats
There is an easy way to work linear birds from mobile. All you need is a single band SSB mobile radio (FT-857, FT-897, etc), a portable SSB receiver (TH-F6, etc.) and very simple antennas for the downlink (like the CJU for mode J, 1/4 whip for mode B, etc): http://eb4dka.laserenadigital.com/Amateur%20Satellite%20Articles/FO29_MOBILE.pdf http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20via%20FO29%20desde%20movil.html I´ve made hundred of QSOs via FO-29 using this little station. It also works nice on FM birds. Best 73s Pedro EB4DKA http://eb4dka.laserenadigital.com Show me an all-mode HT that retails for the same sort of price and is the same sort of size as an FM HT and I might be interested. Otherwise, to get UHF and VHF SSB I'm stuck with an inconveniently large radio which is only really useful for the twenty minutes a day that a satellite is overhead. Not to mention the difficulty involved in tuning the radio and aiming the antenna. Doesn't the Doppler shift mean you need to constantly retune? How do you manage to do that, key the mike and point the aerial, *and* have enough brainpower left to make a contact? Gordon MM0YEQ ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: TH-F6A tip request
Hello Scott and all, I've used my TH-F7E (european version of the TH-F6A) to work satellites in many ways: -As a portable HT station for the FM birds using either an AL-800 telecoping whip or a dual-band beam antenna (Arrow, IOio...). Although full-duplex is the best way to go, You can work fine using half-duplex. See video for details: http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20portable%20via%20AO27.html -As the receiver side of my mobile station using a CJU antenna to work FM and SSB birds (FO-29, HO-68). I use an old Kenwood TM-255 all mode VHF transceiver and a 1/4 wave mag mount VHF whip for the uplink. This setup allows me to work full-duplex. See video for details: http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_EB4DKA%20via%20FO29%20desde%20movil.html -As IF receiver for my AO-40 base (and mobile!) station: http://eb4dka.laserenadigital.com/Videos%20AMSAT/VIDEO_Kenwood%20THF7%20recibiendo%20el%20AO40.html http://eb4dka.laserenadigital.com/Imagenes/EB4DKA_AO40_MOBILE.jpg I found the B receiver as sensitive as A receiver in FM. In SSB I've compared it with a TS-790 and a PCR-1000 and the sensitivity is almost equal. The big downside is the bandwith filters in SSB (they're pretty wide), but you can work quite well if you stay away strong adjacent stations. Just my two cents... 73 de Pedro EB4DKA http://eb4dka.laserenadigital.com - Original Message - From: Greg D. ko6th_g...@hotmail.com To: scott@gmail.com; amsat-bb@amsat.org Sent: Thursday, February 03, 2011 7:17 AM Subject: [amsat-bb] Re: TH-F6A tip request Hi Scott, I haven't used my F6 much for satellites (my D7 is better, but mostly I use my FT-736r. Warm, in side the shack. The F6 is an interesting beast. I have used it with an after-market speaker mike, the kind that clips over your ear and has a short boom for mike pickup. It works ok, I suppose. The audio volume (from the mike pickup) wasn't all that good. It's kind of short, and as I don't like talking loudly into thin air, I kind of cup my hand over the boom and mouth, which kind of defeats the whole purpose of it. Also the VOX didn't work, and I think one of the PTT buttons (the one on the speaker mike cord, or maybe the one on the rig itself, would key up the rig but no audio would come through. I just use the other one. The volume in the ear piece itself is fine. You're going to ask me what the make/model is, and I really don't recall. It was from one of those vendors you see at swap mets year after year. Nothing is written on the unit itself. Fortunately, one of the wires got run over by something and it's in need of repair. Instead of doing that, I picked up a Pryme SPM-301B at a recent club white elephant sale. Seems to work in a quick smoke test, but I don't have any on-air results yet. The ear bud doesn't clip over the ear like the other one does, so I'm concerned it might keep falling out, but the price was right. The F6 itself, at least mine, is somewhat deaf on the B side. If you're on an FM bird, use A for receive, and if you want to transmit, do that on B. For SSB/CW, you will have to use the B side, of course. Note that it is a half-duplex rig, so you will not be able to hear yourself without a second radio. Also, the B side is pretty wide banded and weakly filtered, so you're going to get some imaging effects and intermod in high RF areas. If you haven't yet, do invest in some sort of protective cover for the keys. The lettering on mine is almost totally gone, just from sitting in the side pocket of my backpack/laptop case. If you find, one day, that the rig doesn't power up, take the battery off and give the two spring power clips a little tug. Mine seem to not make good contact sometimes. That's all I can think of, off the top of my head. Definitely a cute little rig, with lots of uses. The B side's wide range and SSB/CW capability makes it a portable instrument, an IF receiver (for on-roof tuneup of my AO-40 downlink), and the AM/FM radio comes in handy from time to time. Once I even checked into the regional SSB Net on 2 meters, receiving SSB on B, and using the PTT on A for crude CW. (Hey, it worked!) Pity we can't listen to TV-audio anymore. The Li-Ion battery has very little self-discharge, so it's always ready to go.

I usually work the FO-29 using a TH-F6 as the downlink receiver from mobile.

My sincere thanks to Ed, N4ALE, who loaned me his TH-F6A for the weekend. I picked it up Friday afternoon and returned it Sunday afternoon, giving it a pretty good workout in the interim – well, part of it. I can’t tell you how it performs on AO-27, AO-51 and SO-50 because I never tried it with any of our FM satellites. In fact, I never keyed the radio’s transmitter. Instead, I focused on its receiver. The TH-F6A proved to be a capable receiver for use on AO-7, FO-29 and VO-52. If you have an all-mode radio that will operate in CW and SSB on the UHF and VHF bands, you can use the HT as your receiver for a full-duplex station that will work our linear-transponder satellites. For the record, I believe the current-production all-mode transceivers that are NOT full duplex include two Icom models (IC-706MKIIG and IC-7000) and three Yaesu models (FT-817ND, FT-857D and FT-897D). Anyone with one of these rigs and the Kenwood can do what I did last weekend. Just add antennas, or a duplexer and a dual-band antenna. There are plenty of workable options, including a good number of homebrew antenna designs to consider. I started out Friday evening just listening because I discovered I needed an adapter to connect my headphones to the receiver jack on the radio, which takes a 2.5 mm connector. Full-duplex contacts in SSB wouldn’t happen until I had that, so I connected my Elk and configured the radio’s B-Band to receive SSB in the 2 meter and 70 cm pass bands. It’s easy to set up, and the fine-tuning feature permits tuning steps in CW or SSB as low as 33 Hz. I chose 100 Hz, which worked well. Switching from CW to SSB took only a few seconds. Through the evening, I copied AO-7 on multiple passes to the east and west of my location, and had reception below 4 degrees at the end of the passes, which was encouraging. Just before 03:00 UTC Friday evening, I had a VO-52 pass that reached a maximum elevation of about 70 degrees here. I copied practically the whole pass, hearing K8YSE work AA5PK and KB1PVH, and also clearly copying CW from W8IJ. Here’s the fun part about that pass – I was standing in my driveway, using a Diamond SRH-789 telescoping whip for an antenna. Having the ability to copy pretty much the whole pass with just a whip helped me to see that the TH-F6A probably would do OK as a satellite receiver. After picking up the headphone adapter I needed Saturday morning, I started working passes. Using an SMA-to-SO239 adapter, I connected the HT to the Elk using a Diamond duplexer. I used either a Yaesu FT-857D or a Yaesu FT-817ND as my transmit radio. The earliest afternoon pass of AO-7 hit 3.8 degrees maximum elevation here, but I heard my CW signal and called CQ a few times with no answer. The next pass of AO-7 was well over 30 degrees here, also to my east. I worked N3TE in CW, then switched to SSB and moved up the pass band for a voice contact with K3SZH. By then, AO-7 was descending to my north, so I switched back to CW and started calling CQ – primarily to see how long I could hear myself through the HT on the downlink. I was thrilled when K4YYL called me. When we finished that contact, AO-7 was at 2.6 degrees elevation according to the computer. I should mention here that I was manually tuning for Doppler throughout the weekend, which also gave me a chance to use various software packages as my “guides” for finding myself at the start of a pass. Ham Radio Deluxe’s Satellite Tracker, Orbitron and SatPC 32 all proved very helpful. After launching one of the programs and getting the Doppler tuning on screen, I just followed their lead and found myself quickly, then stayed where I needed to be – evening tuning up and down the pass band to call others I heard. On the next pass of AO-7 (the last of Saturday evening for me), I worked K4YYL again – this time in SSB, and this time using an FT-817ND at 5 watts out for my transmitter. Think about that – a fully functional all-mode satellite station that I could fit in a day pack with room to spare! FO-29 later Saturday evening was frustrating only inasmuch as there weren’t many folks around. The first pass here hit less than 20 degrees maximum elevation to my east, and I called CQ in CW without a contact. The next pass was about 70 degrees maximum elevation, and I talked to myself for the first 2/3 of the
