OK so i have two Yaesu FT-60R handhelds, and i want my sister to get a radio license so we can talk, but my second Yaesu wont receive when i transmit on a repeater with my handheld, but i can talk to other people with handheld on that repeater, but not my other other radio.

Please, please, please help i have no idea why they wont receive each other!
(i just got my license like 2 months ago and i don't have much of an idea of what im doing so if there is an obvious reason that im missing that's why)

Reply's appreciated

My first guess would be that PL or DCS decode is enabled - If you have a manual, try to turn these off and check simplex between the two radios.

How far apart are the two radios? If they are close (same room) then the one transmitting is probably desensing the other receiver and preventing it from hearing the repeater. The repeater signal is much weaker than the other HT in the same room. This is a common issue.

Yes they are, but i have tried them about 500 Ft apart on my local repeater and have someone listening on the other radio but they never receive each other

So, both of your HTs can talk to other stations through the repeater but they cannot talk to each other through the repeater???

There's got to be something else going on. If each of the HTs can work other stations via the repeater there is no setting that I can think of that would only prevent them from talking to each other via the same repeater. The only thing (which is pretty common) is front-end overload on the receivers but I would not expect that to occur with a separation of 500 feet.

I'd try multiple times at 500 feet (or more) just to make sure that one of the HTs was not failing to hit the repeater during one test. Even better, get another ham to use one of your HTs so you can try it both ways and have someone familiar with radio operation at both ends.

From what I am reading, I would say the transmitting radio is overloading the receiving radio's front end.  You might try setting the two of them on simplex and see if that works.

You are too close.  Remember, the repeater memories are transmitting on a different frequency than they are receiving.  You are overloading the front end of the other radio.

Get away from each other or go to simplex.

Simon - I'm going to agree with what W4CKR said. Take your time and slowly go through both radios to make sure all your settings are correct for that repeater. Check PL tones, if after checking everything is still doesn't work try using a simplex frequency between the two radios like 146.520 just to make sure there isn't something actually wrong with either of them. I hope I'm not telling you things you've tried already but sometimes you might overlook something because you're SURE you set it up right.

Since each radio independly is able to talk with other stations on the repeater, all settings like offset, PL tones, etc have to be correct on each of the radios. The ONLY possibility is that when trying to talk to each other through the repeater one receiver is being blocked (overloaded) by the the other transmitter which is transmitting on the offset frequency. When you release the PTT on the transmitting radio you should hear the beep tone and repeater squelch tail on the other.

Any update on solving the problem?  when checking several of my radios, I put them in low power mode, i.e, 1/2 watt than both radios can be in the same room with out overloading them. As stated before, set both to the same simple freq and verify that you have communication between them.

No they still wont talk on a repeater (so far) but on a non-repeater frequency (145.555) i turned the power down on mine and they could talk so i still need to test it on a repeater, which i will do soon cause i know someone who is a ham and ill ask him to help. but hopefully turning the power down fixed it.
Thank you all for helping!

Try 'listening on the input' with one of the radios ( press the HM/RV key ) as someone talks on the other.
If that works try taking each way with one in reverse offset mode and the other normal .
When you press the PTT key you should see the displayed frequency shift.

Yes they are, but i have tried them about 500 Ft apart on my local repeater and have someone listening on the other radio but they never receive each other

I don't want to sound like a jerk or anything, but it is necessary for you to be able to talk through the repeater using one of them to talk and the other for receive? If you can use each of them separately successfully and you get good signal reports, that's all that matters. If you have to talk from one to the other, you can just switch to simplex.

I still think 500ft is to close for a real test. Give one HT to a friend and have them go across town or something - at least a mile or so away from you, and see how that works. It COULD be overload on the receiver, but I've accidentally talked on my base station (with antenna in the same room I'm in) while I had my HT on, and although there was plenty of feedback squealing from the speaker, the HT could definitely pick up the base station through the repeater.

At any rate, I hope you get everything solved. Weird problems sometimes come up with amateur radio, but solving them is part of the fun. Take care.
