Terms
by Arthur Feller, W4ART 19 Mar '16

Hi!! Seems that many folks need clarification of some common operational terms. Here are definitions from the radio regulations (2012 edition). RR 1.125 simplex operation: Operating method in which transmission is made possible alternately in each direction of a telecommunication channel, for example, by means of manual control2. RR 1.126 duplex operation: Operating method in which transmission is possible simultaneously in both directions of a telecommunication channel2. RR 1.127 semi-duplex operation: A method which is simplex operation at one end of the circuit and duplex operation at the other.2 2 1.125.1, 1.126.1 and 1.127.1 In general, duplex operation and semi-duplex operation require two frequencies in radiocommunication; simplex operation may use either one or two. I hope this helps. 73, art….. W4ART Arlington VA To thrive in life, you need three bones: a wish bone, a back bone, and a funny bone. - Reba McEntire http://afeller.us <http://afeller.us/>

Re: [amsat-bb] Trouble programming a TS-2000
by Rick Tejera 18 Mar '16

18 Mar '16

Tom, Craig, N6RSX has been corresponding with me off list and mentioned that the radio in sat mode is cross band. That turned on the light. Exactly what you noted. When i was trying to enter the 2m downlink into VFO A, VFO B was already in 2m. So i set VFO B to 6m and bingo, VFO A was able to go into 2m. Once I put in the downlink, I was able to switch VFO B to 70cmnd program that in. Thanks to Craig for a lot of other good advice and You as well Tom for confirming the problem for others. Now to see if I can get on the air....... 73 Rick Tejera (K7TEJ) Saguaro Astronomy Club www.saguaroastro.org Thunderbird Radio Club www.w7tbc.org 623-572-0713 623-203-4121 (cell) SaguaroAstro(a)cox.net From: Tom Moretto [mailto:[email protected]] Sent: Friday, March 18, 2016 7:59 AM To: Rick Tejera Subject: Re: [amsat-bb] Trouble programming a TS-2000 Hi Rick, just a tip, because it happened to me ;-) When you're going to program one vfo, make sure the other is not on the same band or you won't be abble to enter the qrg. 73, Tom F8COD 2016-03-16 5:22 GMT+01:00 Rick Tejera <saguaroastro(a)cox.net>: All, Cross posting from the amsat-na fb page: OK TS-2000 users, I finally have some time and decided to program the sat memories in my TS-2000. Now according to the manual you put the downlink into VFO-A and the uplink into VFO-B. Straight forward enough, problem is when I select VFO-A on the sub receiver to add it, I can't seem to make it find the 2m band. It goes from 70cm to 6m. I have no idea why it's doing this.

Re: [amsat-bb] Squelch setting on TH-D72a for FM birds - newbie question
by Rick Tejera 17 Mar '16

17 Mar '16

Sounds like you're ready to transmit. Two things to add. First, And I presume you've already done this, but make sure you a 67.0hz PL tone programmed on the uplink frequencies and on with a 74.4hz tone, so you can turn it on if needed. Next, I set the Audio balance (menu 120) to A band, mute the Tx band. A headset is a good idea for the reason you state. You can use a set of ear buds and still use the Mic. I use a Heil traveler head set with boom mike. I like it since it has interchangeable interfaces for different radios. I've got the adaptors for all my radios. Unfortunately Heil realized they can sell more headsets by discontinuing this model rather than just selling $10.00 adapters. I fashioned a Y cord for mine so i can plug a digital recorder into the downlink side of the headset. Fits between the headset and the radio. Enjoy yourself, trust me, the only thing better than the first time you hear your signal on the downlink. is making your first QSO. Still remember mine like it was yesterday.
