I found it does not take ut it is just the radio itself causing this issue it is not the amp alone . I am going to try toroid coil.

Here is what I found...

I got new cable seems to fix radio messing with HRD. Before new cable just the radio alone just 50 watts would mess with HRD. Now that problem is fixed I can even run the Amp no issues with HRD except on 40 meters. I also orderd toroid coils when they arrive i will place them on new cable. The new cable fixed 95% of the issues i was having. Thanks to everyones advice. Be safe.73s

Does anyone know of other programs such as HRD  that controls the Icom 7300. Is HRD  the best program or are there better ones. Thanks for any Advice. 73s

What is your shack/antenna configuration? You should not be having all these problems with RF in the shack at 100w unless something is seriously wrong...

Icom 7300 Question:

If I want to notch out a signal can I do it by touching on the screen or do I have to go to menus and dial in the notch?

New Firmware: v1.30

http://www.icom.co.jp/world/support/download/firm/IC-7300/1_30/

Changes in this version

    A SET MODE item is added to expand the transmission passband width for the SSB data mode up to "100 to 2900 Hz".
    A SET MODE item is added to make the USB SEND/USB Keying function active immediately after USB port connection. The Menu structure is changed accordingly.
    Other performance improvements and bug fixes

There are multiple pieces to this. There is a notch hard button on the front panel.  One single press is auto-notch.  Good for SSB operation.  It will find and notch, multiple carriers in the passband automatically.  Useless for CW, or digital modes as it tries to notch them out!

Next press of the button is Manual notch. Good for all modes.   If you press and hold it will bring up the mini menu and you will have some choices as to width, and  frequency of the manual notch.  press each item on the menu to change the parameter with the multi knob.  However If you wish to have a visual indicator to help to tune and notch out that annoying signal, bring up the Audio menu first and look at the lower left hand display scope, and locate the carrier and move your "notch" over the carrier and watch (and hear)  it disappear into the black hole.

It is satisfying to see and hear that offensive carrier disappear into total oblivion.  :)

I read the specs and several reviews.  Several mention the antenna tuner, but I've not been able to find out the actual specifications.  Anyone know the range that the antenna tuner can handle?

My plan was for a 66 foot OCFW and was hoping to use it on 10, 20 and 40 meters.

I/Q Signals --  IC7300?

I would like to use HDSDR with the 7300 but from what I can see there is no way to get the I/Q signals it  needs to display the spectrum??

3 to 1.
And it seems more limited then other 3 to 1 tuna's.
My Flex has a 3 to 1 tuna and it tunes almost everything, the 7300 would tune very little.
Ignore the built in tuna and buy a good one, auto or manual.

In normal mode (100 watt output) 3:1 SWR is all it will do.  You can sort of "fake it out" by tuning at a frequency that is no more than 3:1 then you can move out of the 3:1 range with the VFO as long as you don't do a retune it will continue to work with a small SWR rise  on a frequency that the tuner will not tune. Does that make sense?  Kind of a hard concept to verbalize. BUT it will work.  

If you go into Emergency mode (50 watt power limited) it will tune much broader loads, some of mine I believe are about 7:1 but kinda hard to prove as my meters don't go that high. But much more than 3:1 for sure.

You have to choose Emergency mode from the menu, and reboot the transceiver.  Whole switch-over process takes about 10 seconds.

I hope this helped. Oh, your OCFD should work in normal mode without any problem.

I have a new 7300 and I like it, but one thing bothers me.  The TX indicator in the upper left side is always visible and get brighter red when in transmit.  Why would not they have it be GREEN and say RX when rx mode and go Red TX only when in transmit?

Anyone found a way to get rid of it or change that?   The Green/Red TX/RX LED next to the tuning knob works as you would expect.

Well, that indicator is NOT the tx/rx led.  As you know they are near the tuning knob.  That indicator also will have a dotted line around it when you are "out of band" indicating that transmission is not possible.
