I must be stupid!! I have read the manual over and over and I still cant seem to figure out how the split works!! If I set my spilt to 500hz that means that my rx is 500 lower right? If I set my spilt to 500+ and the freq is 27500 then I will tx on 28000 and rx on 27500. If this is right then the other person has to set his spilt reverse, he will tx on 27500 and rx on 28000 right.
Help me I am going nuts!!!! |

Radio.....
MOST offsets work like this
29.620 offset -100 ( transmitt 29.520 )
29.620 offset +100 ( transmitt 29.720 )
reverse split -100 recieve 29.520 transmit 29.620 However i also have seen where it means that a -100 becomes a +100 like a 29.620 -100 split would give a 26.720 xmit frequency.
So radiodude break out the keg im on the way and we can go nuts together!
PS PET PEVE you buy a VX-5 HT for 6, 2 and 440 radio its 1/2 the size of a pack of cigaretts but the owners manual weights 22 lbs. Radio ..... make that 2 kegs! |

No Radiodude... Easy mistake/mis-understanding. The confusion starts with the missing digits that your frequency display isn't telling you about. Your "27500" is actually 27.500000 (three more digits not shown tor each the "hz" value). Your display doesn't show the "hz" digits... minus 500hz would be 27.499500...plus 500hz would be 27.500500.
Example:
Lets say you are listening to a station on 27.555 and they say they're listening to 27.550...your split should be minus 5000hz (or 5kHz).
Hope this helps! |

Man O man Am I confused!! I have a "gentleman" around here that dead keys me and I want to get away from him and drive him nuts. I was tring to figure the darn thing out but I just dont get it!!!
My 2995DX is the best radio I have ever had but it makes me crazy that I cant get the spilt to work!
You dont have to be going through a repeater to make it work do you???? |

Working a split can be the most enjoyable QSO.
While some will racking thier brains to figure where that DX station is, you are one of the few who has figured him out and having a nice QSO with 'em. ( I have founf it is between 500, 600 and some times 800 being used, up or down :
not using 2mtr just HF ) And of course , you can get used to the split by , , using that
nasty wored . . . morse code ! It always uses
a split. ( P. S. I have VX5. Nice radio 0

Radiodude,
No, you don't have to go through a repeater to make it work. Although you do need 2 transmitters that are capable of working split frequencies.
You answered your own question in your first post. Lets say one radio is on 27.385 and the split is
-20khz, you would be on 27.385 (rx) and 27.365 (tx). The other radio would have to be set on 27.365 and the split being +20 khz. So it would be on 27.365 (rx) and 27.385 (tx)
These are just examples of frequencies.
The first time I heard someone using split frequencies, I thought the guy was a few cards short in the deck. Talking to himself that is. Then I ran across a 2970 that I picked up, and seen what was going on. Hope this helps, just my $.02. Have fun, and enjoy!

Radiodude, the "split" frequency operation has two popular uses:
1. Repeaters...to receive and retransmit a signal at the same time you must use a dirrerent transmit and receive frequency...more commonly referred to as "Repeater Offset"
2. Some DX stations use "split" frequencies...again, meaning different receive and transmit frequencies.
Example:
Lets say a station is calling "CQ DX" on 27.555 MHz and he/she says "listening down 25 kilohertz (or 25000 Hertz)".
- That means they are transmitting on 27.555000MHz and want you to transmit on 27.530000.
- It's a simple math problem...27.555 - 25.000 = 27.530
Also, sometimes they may say just the numbers >>> "listening down 5" or "down 10", etc. They mean 5kHz (5000 Hz) or 10kHz (10,000 Hz). etc. |

Those splits are great to use when you have a buddy that has the features as well. It comes in handy when you have a local that likes to try to cause problems. You each plug in those TX and RX freqs you want and away you and your bud go and enjoy the conversation with no problems..!!! What will really get the clowns confused is to use the splits on FM!!!!! LOL! |

Ok I got it! My pal has to be opposite me.... like this, if I rx on 27500 and have a + 200 then he will have to set his radio to rx on 27700 with a -200 so I can rx him
RIGHT??? |

Hi Team,Radiodude you are right on for simplex.But if you go to use a repeator both stations must be set up the same.
