Sprotnik Posted August 1, 2016 Report Share Posted August 1, 2016 Hi. Here I am again asking for your help and knowledge... I had a shooting last week and a friend of mine borrowed me a comtek system (one transmitter M-216, and two recivers PR-216). I had work other times with comtek and no issues, but this time... the comtek system was useless... the system seems to be a little weird for me because the transmitter had the usual antenna, but one of the reciver had it too and the other one doesn´t. first time I see that! the point is that the RF noise is almost the only thing that the recivers recive I can´t guess if the system is wrong, the transmitter is broken or what... other issue is that Comtek hasn´t a dealer or technical support in europe and I would have to send it to the USA just to guess what happens I´m attaching some pics, maybe you have some clue from it... one reciver the transmitter the transmitter transmitter again the other reciver with antenna a closer one of the transmitter with antenna I would appreciate any help regards!

Philip Perkins Posted August 1, 2016 Report Share Posted August 1, 2016 I think you have 2 transmitters there.... Quote Link to comment Share on other sites More sharing options...

The receivers come in the option 7 flavor as well. The labels in the pictures identify one transmitter and two receivers. As for your RF noise, did you try switching to a different frequency?

Sprotnik Posted August 1, 2016 Author Report Share Posted August 1, 2016 No, it's just one transmitter and two recivers (see model spec. PR-216) But, being the same model... One has antenna and the other one doesn't!! Isn't it weird? Yes, I haven't mentioned it... I have tried changing frecuencies, and nothing, it doesn't work 47 minutes ago, Patrick Farrell said: The receivers come in the option 7 flavor as well.

Sorry, Patrick, I don't understand what you mean with "the option 7 flavor" Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted August 1, 2016 Report Share Posted August 1, 2016 Option 7 is the Comtek mod that adds that antenna. Standard 216 stuff doesn't have them, they are an add-on. If they really are two RX from the 216 series and one works on the designated TX freq and the other doesn't then the non-working one might be broken. Have you tried going "around the world" on the RX freq selector dial to see if another setting finds the TX better? Quote Link to comment Share on other sites More sharing options...
carbonhobbit Posted August 2, 2016 Report Share Posted August 2, 2016 Maybe a case was broken and a transmitter was cased in a receiver's case. Plug the input cable into it and see if it transmits to the one working receiver. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted August 2, 2016 Report Share Posted August 2, 2016 Both the M-216 transmitter and PR-216 receiver are available with option 7: http://comtek.com/m-216-option-p7/ http://comtek.com/pr-216-option-7/ Quote Link to comment Share on other sites More sharing options...
Daniel McIntosh Posted August 2, 2016 Report Share Posted August 2, 2016 I can see a potential problem: were both transmitters turned on at the same time? Quote Link to comment Share on other sites More sharing options...
Sprotnik Posted August 2, 2016 Author Report Share Posted August 2, 2016 So, it has to be one reciver with option 7 and another one standard. It both recive the same weak signal, and I think it's not about the freq or channel selection (I have tried several of diferent configurations) Quote Link to comment Share on other sites More sharing options...
carbonhobbit Posted August 2, 2016 Report Share Posted August 2, 2016 The option 7 receiver says it is a line level output. I would think this wouldn't work with headphones. Quote Link to comment Share on other sites More sharing options...
Christopher Mills Posted August 2, 2016 Report Share Posted August 2, 2016 can you borrow another system to compare? just a single transmitter and receiver. You may have a bad transmitter. You still won't get a headphone signal out of the receiver with bnc antenna Quote Link to comment Share on other sites More sharing options...
Sprotnik Posted August 4, 2016 Author Report Share Posted August 4, 2016 yes, you are right I´ll try to get another transmitter to check the system. I think I have a bad transmitter and it is all what happens... thanks a lot Quote Link to comment Share on other sites More sharing options...
PhforAndAfter Posted August 6, 2016 Report Share Posted August 6, 2016 I had a Comtek Tx go down on me last month. I shipped it to Comtek and they replaced it with no charge. Apparently the crystal had broken somehow.Sent from my XT1096 using Tapatalk Quote Link to comment Share on other sites More sharing options...
