Kenwood tk-270

[jfpolacko]

I got a Kenwood TK-270 that I just got and I'm fairly new to... My issue is that I can key up to transmit but no voice! But you can hear the thump if you tap on the mic.. Me and my buddy was trying to talk on a simplex channel but every time i go to transmit (No Voice) is there a setting that might be off? or does anyone have any ideas as to what that might be?

 

[krokus]

Is that with a speaker mic, the built-in mic, or both?

 

[mmckenna]

How close are you to your buddy when you are trying this?

 

[jfpolacko]

Both the built in speaker and with plugged in mic and speaker... and we are doing this pretty close and we even tried to talk on a repeater...

You may be close enough to the other radio to be completely overloading it. Try getting a few hundred feet apart and see what happens.

That don't explain why we can't talk on a repeater? I can transmit but no voice but we can hear tap tap tap when we tap the mic bot built in and plugged in....

It does depending on the input and output offset. A strong radio signal, even if not on the same frequency, can overload the front end of the receiver.

Other things to look at would be if the radio is really transmitting on frequency or not. TK270's have been around for a while. Could be that it's in need of a tune up.

Okay makes more sense.... I'll have to take it to someone that can tune it up... on another note i got these instructions for field programming

Pressing (TA) will allow you to program Frequencies

Use selector to choose channel
Press PTT

Enter Rx frequency using:
- the Selector Knob to change kHz;
- the Selector Knob + (light) to change MHz.

If no channel is Shown press the (LO) button.
Press PTT

Enter Rx CTCSS code
Press PTT

Enter Tx Frequency as above

Hi

can anyone walk me thru some of these instructions

Okay makes more sense.... I'll have to take it to someone that can tune it up... on another note i got these instructions for field programming


Press and hold (light) & (dial) while turning on radio.

Hold until (SEL) appears on the display.

Pressing (SCN) allows you to program the following

1. Monitor Key
Off = off
1 = Monitor momentary means that it will open squelch while you hold the monitor button if it is set
up to open with a tone like a minitor pager

2 = Monitor Lock open squelch and leave it open till you push the button again
3 = Squelch off momentary basically the same function as 1

2. Scan Key
Off = off
Co = carrier operate locks on ch until the carrier closes then resumes scanning
To = Time operate stays on ch for determined set time in secs set up down further in the list

3. Dial Key
Off = off this is if you have a interconnect system for ph calls or to call another radio if it requires a tone to open the squelch
On = enable

4. TA key
TA = talkaround if you have a repeater and a direct channel you can use this rather than programming 2 chs if it is set for TA when pushed you will tx on the rx channel
RV = Reverse Set for RV you will TX and RX on the TX channel
Off

5. Lo Key
On tx power if you set a ch to transmit on Hi you can temporaly tx on Lo
Off

6. Priority
None
1 = fixed Fixed is determined in initial programming of your freqs or you can set it as selected so that whatever ch your selector is on is the priority ch
2 = selected

7. Fixed Priority Channel
Turn selector to channel this is if you have step 6 set for fixed priority

8. Look back time A steps 8 and 9 are for the look back times when scanning for the priority channel
Turn selector to time in seconds

9. Look back time B
Turn selector to time in seconds

10. Revert Channel (similar to a home channel or while scanning if you transmit and it goes back to scanning when you key up again this is what channel it would go back to)
1 = Selected
2 = Last Call
3 = Last used
4 = Selected + Talkback
5 = Priority
6 = Priority + Talkback

11. Tx Dwell time steps 11-16 I haven't messed with ask an expert lol
Turn selector to time in seconds

12. Drop out delay
Turn selector to time in seconds

13. Time out timer
Turn selector to time in seconds

14. Tot Pre-alert
Turn selector to time in seconds

15. Tot Rekey time
Turn selector to time in seconds

16. Tot reset time
Turn selector to time in seconds

17. Squelch Level this is the overall squelch level for the radio 0-9 is the level options I believe
Turn selector to Squelch

can anyone walk me thru some of these instructions

hope this helps probably clear as mud right lol I use TK270's almost exclusively got several of mine from fire guys over the years off of ebay
