Kenwood TH-F6A

I have a TH-F6A and just got the Arrow Antenna with Duplexer. I can't set my offset to 1.31 according to Kenwood this radio doesn't do that.

Anyone got any ideas to how I can listen to the ISS? I want to see if I can do it and I can work on talking later.

I have not had any luck contacted any sats or ISS yet. I am trying the AO 51 pass over Hawaii tonight.

Thanks and 73s

Hello WH7LH (sorry my english). I have a th-f6a too, using a homemade Arrow antenna and a duplex. I've done contact with satellites AO16, AO51, SO50, VO52 and I was already heard by ISS, and have heard the AO7 (not transmit). This radio has two inconvenience: 1 - FM steps are 5 on 5 kHz, 2 - is not full duplex. So to operate the ISS in repeater mode takes into account the Doppler on the uplink UHF (it is more critical than the downlink) use the reception - 145.800MHZ (downlink) in "A" and transmission - 437.800MHZ (uplink + - Doppler) in "B" not forgetting the squech. This procedure can also be used for operation of the other satellite. Good luck, anything send me an e-mail and we exchange some ideas. 73 de PU9WIL - WILMAR

You can try for cross-band duplex mode

Hi Stacy,

Since the ISS is now in cross-band duplex, you can try to program for that also. You might have to program two consecutive memory channels to do it.

You always get the trivia correct on the net.

What do you mean by in cross-band duplex? What are the freqs for that?
I did, I think, get the radio set up by using the off-set repeater mode.

Problem solved

Will try this tomorrow. But here is what I did.
Storing Odd-Split Repeater Frequencies:
For example, if you want to store a 1.31 offset to talk
to the ISS. (This is a - offset with a 1.31 and this radio
will not do this, it will only go to 1.30 and 1.35)

The Down-link Freq is 145.800
The Up-Link Freq is 144.490
Press VFO
Turn the turning control to the down-link (Receive) freq
Press F
Select a blank channel to store the down-link freq in.
Press MR to store the freq in the channel.
Turn the tuning control to select the desire Up-Link freq
(Transmit) freq.
Press F
Turn the tuning control to select the memory channel you
programmed for the Down-Link
Press PTT + MR or PTT + MNU
To check to see if it is correct, Press REV
