Used Icom 140 or new 130

Reading the threads every day during lunch has kept my spirits up now its time for me to tap in to the well of knowledge.
I have been gathering the pieces to a departure this Fall -- acquired an ICOM m710 and have the choice of a new in the box ICOM (old) A130 antenna tuner or a used A140 (no connecting wires) ---- which one should I chose ---- do they cover the same frequencies?-- what are the differences and how significant?
Thanks for helping the electronically challenged

Re: Used Icom 140 or new 130

I have an A130 and an A140 ( or maybe 141... not sure).

Specs are identical, only difference I can see is the conections to the radio.... 140/141 have a plug and use a dedicated control cable, you have to open the case of the 130 and wire it up inside.

I have the 130 hooked up to the 710, the 140/1 to an IC-706.

Specs here for all three...

■ Specifications
• Frequency coverage
• Power supply requirement
Current drain
• Operating temperature range • Weight
Antenna connector
• Max. Input power •Automatictuningtime
• Automatic tuning accuracy
: 1.6–30 MHz (with 7 m; 23.0 feet or longer antenna element) : 13.6 V DC (supplied from HF transceiver)
: Max. 2 A
: –30C to +60C (–22F to +140F)
: 2.5 kg; 5.5 lb
: SO-239 (50 Ω)
: 150 W (PEP) 100 W (continuous) :Approx.2–3sec.(generalcondition) Max.15sec.
Approx. 1 sec. (re-tuning for a memorized frequency) : SWR 2.0:1 (after tuning, except for multiples of 1⁄2 λ)

Details for connection of the 140 to the 710 are in the manual.....

D When connecting to Icom IC-M710/RT, IC-M700PRO
Use the optional OPC-566/1147 (either the connector to the AT-140 or the transceiver requires assem- bly), or assemble the desired length 4-conductor shielded cable and the connector kits supplied with the transceiver and the tuner.
To AT-140
[STAR] : White [KEY] : Green
[13.6] : Red [E] : Black
To transceiver

Hope this helps
