That is what I have done, built a cheap antenna. I have a Chinese radio and I have made contacts on SO-50, half duplex. I DO NOT get on the linear birds because primary I do not have the means to run 2M/70CM SSB. I can also understand that it would near impossible to effectively make a contact But newbies can/should be given guidance in the form of Elmers. Not being told they are not welcome if they don't have the equipment others have. By the way check the prices an arrow antenna that will give someone the best chance to get into AO-85 with a Cheap Chinese radio is about $150.00. I love VHF/UHF but I can't do much more than be a spectator at this point due to the equipment required. I will get there eventually.
I am just trying to point out that not everyone has the ability and may never have the ability work the satellites with the gear that others have. I would love to have a way to do so but for now it is not in the cards in my household. I am OK with that.
So when the arrows start flying try not to hit the people that you should be trying to bring in the fold to help, in any way they can, put more satellites in orbit for us all to enjoy. Just my viewpoint from down here. 73 Jerry W4JWC

The financial argument is a weak one at best. A WA5VJB Cheap yagi is about 10 dollars of materials (you can skip the diplexer with two radios), and I have recently seen and purchased older full sized 2m HTs and UHF analog only scanners for as cheap as 5 dollars at hamfests. Add a $30 Baofeng and you have a satellite setup for next to nothing.
Don't want to build or can't? The price difference between an Arrow antenna with a diplexer, and one without is about $60, or the cost of TWO cheap HTs. Use the extra $30 to buy some good cables.
I certainly don't mind if those getting started try half-duplex at first, and it has it's place in some situations. I even wrote an article 10 years ago about half duplex ops with the FT-817 on FO-29, which I plan to update soon, but the linear sats are different animals, with different challenges.
Once you try full duplex and realize the benefits of being able to hear if you are causing or being QRM, and being able to twist the antenna during transmit to get a better uplink signal, you won't want to go back to the old way.

Then what I am hearing, "AS A NEWBIE" is that I am not welcome on the Sats because I do not have the financial resources to invest in all the equipment needed to run full duplex. It is more than two cheap Chinese radios, it also involves an antenna, which at the very least it is almost double the cost of the two Chinese radios.
Money that some of us have a hard time pulling together.
I have a hard time with all the purest, my way or the highway mentality I am hearing.
Just my 2 cents

I could care less whether you have ever uttered it or not in one of your live presentations. It is printed in black and white in your handout. You just quoted it yourself. The minute you typed that phrase and began giving out handouts or telling people to print it out you became guilty of spreading ignorance as far as satellite operation is concerned. You are leading newbie sat operators down a path they should not be on. If one does not have the means to hear their own signal coming back from the bird so as to insure they are "making it there" then they should not be on the satellites. End of story.

You've never attended one of my sat sessions. I have never uttered the sentence to groups, "It is not mandatory to work full-duplex. - PERIOD." My standard mantra for the easy FM birds is all over the place:
"Ideally, we should be working the satellites in full duplex mode, where we can simultaneously listen to the downlink as we are transmitting. Although this method is preferred, it is not mandatory: Carefully monitor the downlink, and wait for a break in the conversations to announce yourself."
People you might be hearing stepping on others are not following those instructions.
And all my audiences are very graphically shown and told the reasons why working full- duplex is preferable.
I didn't work full-duplex when speaking with Commander Wiseman - who was aboard the ISS at the time during Field Day 2014.
If you haven't already given a presentation to your club on working the easy birds, I am available. Just send me an email message.
