Hi All.

I have had an Icom IC-7000 for over a year now, having bought it second hand. Today I went to use the for a few SSB QSOs on 20 metres when I realised I couldn't get more than 40 watts out.

Initially I thought that the PA amp may be at fault, but after playing around some more, I learned that the power I get varies wildly with band. Setting the radio to 100% power out, I get the following measured powers with a Bird Thruline into a dummy load:

- 160 metres, 1 watt.
- 80 metres, 1 watt.
- 40 meters, 10 watts.
- 20 metres, 40 watts.
- 12 metres, 60 watts.
- 10 metres, 90 watts.
- 6 metres, 30 watts.
- 2 metres, 49 watts (fine).
- 70 cms, 37 watts (fine).

It seems the issues are in the HF PA, i.e. anything on Antenna 1. I'm not sure what the issue is. I think something like a capacitor gone down, or a relay stuck? I'm not sure.

Any help would be greatly received.

Thanks in advance.

Hi,
I'm interested in this portable antenna (MP1 SuperStick Portable Vertical) to use when on trip.
Anybody have this antenna using with IC-7000 ? Could give me an opinion ?

Other option is ATX-Walkabout, but this one is just for QRP operation and MP1 accept 100W without problems.

Thanks.

I'd like to use my THP 550 watt amp with my Icom 7000. The diagram on page 21 of the Icom 7000 manual is not very clear. The amp has the ALC and STBY inputs, as shown in the diagram. And I have the13 wire cable supplied with the IC7000. Connecting the blue wire to the ALC is clear. The THP manual says, ""Connect the control cable from the ACC terminal (or SEND, TX GND etc.) of the transceiver. The center pin is to be shorted to ground through the relay circuit of the transceiver." Does the IC7000 have an internal relay? Do I connect the orange HSEND cable to the center pin of an RCA cable and the gray to the shield? Appreciate any help. Dick, K1MGH

Found the answer to my problem this weekend by fooling around and adjusting the output attentuation level in DM780 to its highest setting. Transmit power stays pretty steady now allthough I still show a couple small bars on the ALC meter on the radio, I havent had any complaints. Apparently my soundcard in my computer is extremly sensitive and by adjusting the output attentuation level to it highest setting its more easily controlled.

The ergonomics of the 7100 are all wrong for me as a mobile user.
My IC7000 control head is mounted face up on the centre console just behind
the gear lever. I have a remote 4" monitor on top of the dash for the
display. This way I can keep my eyes on the road and operate the controls by
feel. My arm rests on the centre arm rest and so makes controlling the radio
very easy.
The angled display would not allow me to do this. Also, the touch screen
would be very difficult to use without looking at it so not happy about the
safety issues doing that. I use my mobile a lot on rough roads (or off road)
so having to reach for the controls on a dash mounted control head would be
difficult and touch screens almost impossible to use without stopping first.
I need the separate head but with a separate (from the controls) screen. I
will be keeping my IC7000. Maybe a 7100 with a flat non touch display and a
remote display option instead of the angled set up should be considered by
Icom. It wouldn't have to be a colour screen though that does help with all
the information available on the IC7000 screen.

I'd rather have the 7000's color display and have the control head on the radio. More stable that way. Although there are a lot of D-Star systems around here I am still undecided on whether it's worth the extra cost; for me the VHF/UHF on this radio would be for SSB, satellites, JT65 etc rather than FM repeaters (which I already have other radios for). I'm told receiver sensitivity may be better on the new radio though.

The 7000 didn't replace the 706 series right away. But there were some pretty good close outs on new 706's when they finally stopped making them. Give a couple years after the new radio is out and they may do the same with the 7000.

Lot's of discussion about the 7100. I'm wondering what the destiny will be for the 7000. I'm really surprised that the display on the 7100 is not in color. Also with the must be detached faceplate I'm not sure that will work for everyone unless it will be used for mobile only.

Wondering what your thoughts are on the future of the 7000. Do you think it will be phased out by the 7000?
