Best HT for satellite operation?
Message: 10 Date: Thu, 9 Mar 2017 14:17:14 -0500 From: Tucker McGuire [email protected] To: Andrew Glasbrenner [email protected] Cc: "[email protected]" [email protected] Subject: Re: [amsat-bb] Best HT for satellite operation? This is a loaded questions and every HAM I've ever met has opinions... It is better to ask what HT's fit SAT OPs functionality:
Everyone wants 'full duplex', I've not seen a dual-band HT that can do 'real' RX while the PTT is pushed, period!
Nest shoot for - What dual-band HT can program SAT offsets (in the SAME single memory)? My definition: in one memory can program both 2m-RX AND 70cm-PTT or vice-versa. Why: you only need say 4 or 5 memories per SAT for AOS/LOS OPs - one less hand needed and far less hassle. I know Yaesu and Wuoxon can do this via PC Program. Kwood TH-F6, Icom IC-91/T8, Alinco G7 cannot they can do it only via flipping the A/B Bands (pain in the butt) - they do not allow cross band offsets in memory.
Now another BAD issue with Yeasu & Wuoxun is they both have a high discharge rate of battery when in the OFF state. I found if I leave my HT's on the shelf for +60days I must isolate the battery for the radio to eliminate wasteful discharging dropp[ing a B-Meter bar. I do this by using a 'paper' business-card cut it to size, sandwich between the battery and HT - isolating the battery contacts. Easy, simple, effective, cheap - what HAM Radio is all about.

You are simply wrong. The Kenwood TH-D72, D7, D7(G) as well as the Yaesu FT-470 and FT-530 all are excellent full-duplex HTs with no desense.
It appears you are suggesting that people operate half-duplex. That can work somewhat, but is definitely not something I would ever recommend.

Dear friends
Do not forget the yaesu FT-51R, works perfect in full duplex mode.

Even the $30 Baofengs support cross-band memories for sat operations. That's how I started, but as Paul said, half-duplex on FM should not be condoned now, especially as our FM birds get more and more crowded and it becomes just an additional source of QRM.
I've been very happy with my D72A. Packet is a nice feature to have to work ISS and NO-84.

My FT-530 most certainly does true full duplex on mode B and mode J. You must be misinformed on the features of these HT's.

I find it annoying that lots of the American HT's don't support cross-band channels. For sure, not the new Icoms, don't think the TH-F6, but all Chinese radios I have played with will do split band channels.

FT-51 will do full duplex on satellite. Duplexer isolation leaves much to be desired. Moderately usable on AO-51. Useless on SO-50, though.
I vote for the FT-50 and FT-51. Personally use both.

I find it annoying that lots of the American HT's don't support cross-band channels. For sure, not the new Icoms, don't think the TH-F6, but all Chinese radios I have played with will do split band channels.

My FT-530 most certainly does true full duplex on mode B and mode J. You must be misinformed on the features of these HT's.

Even the $30 Baofengs support cross-band memories for sat operations. That's how I started, but as Paul said, half-duplex on FM should not be condoned now, especially as our FM birds get more and more crowded and it becomes just an additional source of QRM.
I've been very happy with my D72A. Packet is a nice feature to have to work ISS and NO-84.

Kuby,
When was the last time you were on the satellites? I had a Yaesu FT-51R that was full duplex. I could transmit and hear the downlink of the satellite simultaneously. The Kenwood D72 and the D7 also do it, or are you going to toss some engineering stuff at us to say it's not so?

Dale,
As has been pointed out, there have been many HTs over the years that allow for cross-band full-duplex operation. This was actually a more common feature in the 1990s, and has gradually disappeared from HTs since then. A few years ago, Andrew KE5GDB had a list of HTs and other radios that supported cross-band full-duplex operation on his web site. That web page is gone, but lives on in the Internet Archive's Wayback Machine at:
http://web.archive.org/web/20090724094403/http://www. thathamkid.com/website/ham-radio/full-duplex-radios
For HTs, you could add the TH-D72 to this list, which came out at the end of 2010.
In addition to those HTs, there are a few others that allow for cross-band full-duplex operation in one direction, where you are transmitting on 70cm and listening on 2m. I wrote a bit about a few of the Chinese-made HTs that are able to work AO-85 full- duplex in a series of posts here on the -BB in late 2015. One message I posted in December 2015 that had links to the other posts I made about those radios is available at:
http://amsat.org/pipermail/amsat-bb/2015-December/056269.html
The 70cm receivers in these Chinese-made HTs suffer from desense whenever you transmit on 2m. These radios can be programmed with groups of memory channels to work V/U FM satellites like SO-50 half-duplex, or you could use the two VFOs to do that without the need to program memory channels.
Using separate radios for uplink and downlink is also a good way to have a full-duplex setup. Many have even used a pair of the inexpensive Baofeng-type HTs to have a station capable of full- duplex operation, or one Baofeng-type radio paired with an HT from one of the traditional ham manufacturers.

I've used two Baofengs to work SO-50, and the V transmission from one still desenses the U reception in the other one, even though they are two separate radios.
Do I put low-pass filter in the transmission line to squash that third harmonic?

That should work, though it may not be enough depending on the front end of the other Baofeng.
You may find you need to use a receiver with a better front end to eliminate desense, or two filters.

You may also want to consider adjusting your power level. SO-50 can be worked with very little power and this may help with your desense.
