ICOM M800/AT130

[SilentOption]

Does anyone know if the AT130 will work with an ICOM M800?

It was originally connected to an AT 120.

Thanks

I am not sure on this one and I do not have manuals for the M800. Try calling ICOM Marine Technical Support at 425-454-8155 or by email

If the 710 will I would think maybe the 800 would. If you go to the IcomAmerica web site they show the AT 140 as the tuner option for the 800.

Thanks for the replys. I sent ICOM a message about this and the response was less than positive. They said it was impossible to say becuase they didn't have an M800 to test.

Not exactly what I wsa expecting to hear.

At any rate I am going to take a chance and use the AT 130.

Thanks again

I believe that the AT130 is "backwards compatible" with the M800. Regardless, nothing "bad" should happen when you connect the two.

I really can't believe ICOM can't say one way or the other. I don't want to buy the 130 only to find out it isn't right. Not like I don't own a few hundred other boating items I bought only to discover they don't fit, don't work, or have some other issue that renders them useless.

Bill and Sali-
"I sent ICOM a message" You'll often find that when a company like "Icom" is involved, there are two very different companies you can contact for assistance.
"ICOM" as in "ICOM of Japan" often knows more than "IcomAmerica" which is a separate distribution and service company that owns their rights in the US market. If you dig up the Icom home page in Japan, IIRC there's an option for English version, and they answer questions in English as well. It's often worth asking the REAL company.<G>

Sending a question to ICOM Japan today

Good Idea

Thanks

The tuner differences between the tuners targeted for the amatuer SSB users and the commercial ones are relatively small and may be insignificant to cruisers. For instance the older AH2 and the AT120 differed mostly by the addition of a plug-in LED board on the AT120 which allowed installation techs to log down the reactive component relay positions for each memory location or for a particular frequency once tuning is achieved. Should the auto tune feature become damaged then one could merely set the switches manually to light the appropriate LEDs for that freq and have a "tune". The AH2 would not do that.

The later tuners have slightly different power handling capabilities and some reactive (mostly inductor) value differences mostly to allow lower source impedance at or near 2 MHz (where small vessels have almost no "reach" with their small geometry antennas).

So, in general, cruisers using 4MHz and above with either relatively short transmit times at full power or power limited to around 120W PEP will probably not notice any differences between the AT120, AT130 or AT140.

Thanks Rick

This is the answer I was looking for.
