flex 6600 and satellite ops

  • Question
  • Updated 2 months ago
I have many radios and trying to trim down.. I currently run SATELLITE ops on TS-2000X one evening I ran into a using his FLEX 6600 on satellite. I started to ask question how to do it.
I currently have my TS-2000X up for sale so I can fund two transverters. The question I have is this a wise decision? what advantage will I gain? Having a waterfall on Satellite would fantastic!
thanks in advance

I upgraded from a 6500 to a 6600 so I could run two transverters at the same time. Bought a UHF and VHF Ukrainian transverters and got them working ok. The water fall is nice.


I had an ICOM 910 for SATS, then a ICOM 9100 for SATS later. The 6600 was nice. I LOVE the 6600 for HF.

I bought a ICOM 9700 VHF/UHF/SHF/SDR/water fall/SAT tracking/DSTAR/100 watt radio. GREAT SAT transceiver. 


Sell your TS-2000x and buy a ICOM 9700 for $1450 on sale.

I agree with Kent, I also sold my IC-9100 and got a new IC-9700, a radio that is designed to operate Satellite Comms!!! I use Ham Radio Deluxe with the 9700..

That being said, Transverters for the Flex is also a good option for relatively BASIC VHF and UHF operation.. Glad Flex gave this option especially when operating remote,, but a decent HT radio can also serve one well...

Having a dedicated radio like a IC-9700 has a ton of operational advantages, not to mention the Terminal Mode and D-star operation + Picture Mode you get when on the XLX Gateway!!

But in the end it is what "YOU" think is best for your daily and weekly operational needs!

Full duplex is the feature that matters the most.
I have my Flex-6600 for my base station and use a IC-7300 for portable ops together with an IC-9700 for base/portable satellite ops. 

I know this is a dream but what I would like -

- 2M/70cm/23cm full duplex "box" from Flex
- Flex SDR software would support both radios... One UI but local/remote radios would support respective bands.- Full duplex between different bands.

I have a 25W, Q5 transverter for 70cm, and one of the Ukrainian 2m transverters hooked up to my Flex-6600.  This works very well, and you will really love the panadapter for visualizing what is happening while running full duplex.  I thought the Ukrainian transverter was underpowered on 70cm, so upgraded to the Q5.  It is a very nice unit.  Getting the transverters working with the Flex is very easy.

I use PstRotator for tracking the satellites, controlling the G-5500 Az-El rotator, and providing doppler frequency control for the Flex.  A very powerful software tool for very little $$.  Good luck!

Thanks Joel, tonight I paid for the PstRotator and have got a agreement on my TS-2000X , when ordering the Q5 I see a lot of selections I have a 2m amp for the birds that have 2m uplink, but the T/R rate is a little slow. thanks for the info.

Can you share the purchase parameters you used for the Q5’s ? There are a bunch of options!

I have a Flex 6600, so a configuration that works well for me:

- Common RF
- Common IF
- Keying, PTT-L
- Power - your choice, low power for Sats, Higher for terrestrial work.

The common RF and IF allow you to plug and play without adding external relays.

Here were my Q5 ordering choices:
Common IF
Common RF
IF Drive level : 0dbm to +20dbm
PTT polarity : Low
Filter Tuning: Wideband 430MHz to 450 MHz (so I could also use it for repeaters if needed)
Local oscillator stability : standard
Standard IF : 28 MHz

Good luck! 73, Joel

50 W is plenty and is it’s good operating practice you should always use the minimum required power to communicate. The power is going to vary based upon the quality of your antennas, coax, and the elevation azimuth of the bird.

It depends on your antenna gain.  My antenna, as I recall, is an 8Dbi yagi.  For that, I never use more than 3 watts on the uplink.  Often I need to reduce it to near zero to keep from overloading the Sat.   Antenna gain is really only useful on receive, considering the SAT's TX outputs are in the 10 milliwatt range and coax losses on the ground to the receiver.

Currently, on the AMSAT discussion group, there is a lengthy discussion on this same subject.

For terrestrial, I read that on 2M, anything over 25 watts is wasted due to the necessary power for a line of site range.

I can highly recommend using a Flex 6600 or 6700 for full duplex satellite operation. You can see my setup here: https://www.qrz.com/db/W4AX . I use DEMI transverters for 220, 440, 900, and 1296. For 144 I use a DEMI amp on the 6700. If you use FlexSatPC32 as the software driver it is a great experience. You of course have two panadapters to see all the voice and CW signals.

Good luck,

Mack

Hi Mack - 

I see the article copied from AmSat on the Flex website, but is there anywhere that FlexSatPC is available? Or do you have to get it directly from W0DHB?

id love to try this out, I’m currently using MacDoppler which works great, but I’d like to try this out too. 
Thanks!

I'll also 2nd buying an IC-9700 for Satellite use.  Its simple, clean, gives you everything you need all in a single box.  I'm into keeping things simple and clean these days.

when I ordered my IC-9700 , it came I upgraded to 1.21, then I tried to connect to SATPC32 on Win-10 computer and it was not successful until I change the radio from IC-9700 to IC-910H and then everything worked. I sent a email to the German that wrote SATPC32, 3 weeks later I trade a guy for the IC-9700 for TS-2000X.

So just a follow up to this thread. I have been using a IC-9700 for remote satellite ops and have been happy with it. I was considering the purchase of a second 9700 as a base station with my existing 6600.
When others mentioned that they are using transverters with their Flex for VHF/UHF/Satellite operations, I deployed the two transverters I have had sitting on the shelf but not being used. I purchased them 2nd hand as they seemed like a good idea at the time but did not get around to installing them.
Long story short, I am a dork... Transverter use on my Flex has been an outstanding experience and although the current units I have are 10W units, they hit all my simplex and repeater stations in my geography with no issues. I will start working on Satellites in the short term with the Flex. 
Thank you Flex Radio!

I'm a big Flex fan (own a Flex-6700 and PG-XL) but on this matter I concur with Kent's comments.  Sell your TS-2000X and buy a IC-9700.  It's a much simpler way to go.  The IC-9700 is an excellent Sat rig.

Icom destroyed the used radio market with the IC-7300. I ordered Q5 transverters for my 6600. Started with 2M/70CM to upgrade my Ukrainian transverters and will add 23CM in the near term.

just ordered a Q5 432 transverter and going to use transverter-stores for the 2m I have a pre-amp to plus up the signal
