    Heard one this evening on 38lsb. A local in southern nj or eastern penn. Can't recall his handle/numbers but, I must say with the supplied icom hand mic the transceiver sounedd very nice
    Thanks for the first part of your review. Very informative. And the transceiver seems to be easy to use for the first time HF owner and at $1500 seems like a deal. Used 756 for $1000-$1300 or a brand new rig for $500 more. A no brained IMO. If the general coverage mod can be done for 27 MHz via the menu as opposed to going inside the rig is a plus as I'm sure the important warranty stays intact. I'm not sure if I'd void the warranty. New rig designs sometimes have bugs which require a return to place of purchase or an authorized tec for warranty repairs. Looking forward to your followup.. Thanks

    it can not be done via the menu.

    depending on what you want, 1, 2, or 3 diodes must be opened.

    I'd hate to purchase one, do the 27mrz mod then find out there's a design flaw. The warranties gone and you've voided it. As long as you don't have deep pockets and short arm's you're good.
    I guess that's one of the problems with purchasing an HF and insisting on having it operate on 11 meters.
    If I'm correct there are several hf's that can be programmed through the trancevers menu.
    I looked for a list of those particular rigs but couldn't find one..

    I don't think they can deny warranty work due to mars mod, I once sent in an icom 7200 for warranty and they never said a word about the mars mod,,,, now if you screw up your radio doing the mod then your SOL

    Try to find a used ICOM IC-718, they are about $400 at swap meets. These just need a resister remove to expand the channels and are a good radio.

    Let's try to keep this thread on the topic of the IC-7300. One it wanders it won't come back :)

    Is this a different IC 718, mine has no channels or selector. It does have a VFO, A and B.

    I think I'm seeing two (2) Mitsubishi RD70HVF1C (VHF/UHF) MOSFETs in the final PA section schematic. They are rated at 70 watts each.

    https://www.rfparts.com/rftransistors/transistor-rd/rd70hvf1.html

    Hmm, interesting that they are not using a pair of the standard 100 watt RD100HHF1 (HF) MOSFETs. To save $10...wow? Maybe for the 50 MHz coverage?

    exactly, spin the VFO to 27.385 LSB or you favorite channel,

    Thanks for an awesome review. I own an IC-7100 but this has so many other necessities.

    Hello Moleculo: How does this Icom 7300 say compare with the 746 / 746 Pro radios in having the ability / selectivity to reject near by frequency strong stations, and opposite side band stations on the same frequency? Not a bad price for a new design. Great review.

    Hope all is well.
