Turn on your swr meter and watch that. Wet can make a wire antenna go all woogy, plus, wind can stretch them. The transmitter might have gotten hot too. You need to watch power out, swr, alc, and muf

The tuning of the antenna can have an effect. If its raining or snowing it can alter the tuning of the dipole, lowering its resonant frequency.

Very strange : You have the 8V regulator, then R2011 and C501//C502 ... So you can find suitable replacement on eBay with words like : 100?F SMD Best regards, Ludovic - F5PBG.

...and check to make sure you have clean connections on the head/radio separation area. If you are separated, make sure the screw is present in the connector. That's way too much SWR. Fix the

I was contesting today and toward the end of the day my ALC meter would only go half way to where it usually goes which is to the edge of the line. It then would go to the edge again, drop again etc.

With an SWR of 3:1 or greater ... I can see why the 7K is acting funky. RF is getting into the radio. Ground the radio with a flat braid or flat copper strap and fix the antenna. The 7K is not going

RF is getting in to radio. Try to route coaxial cables away from other power or microphone cables, or any other cable that might provide an inductive path for rf energy to reenter radio. The same

SWR Is "3 or more"??? That's bad. -g-

Good news: Only C501 was shorted. No other damaged parts. Just removed it, and the radio came back from the dead. The sad part is I can’t find a suitable replacement for a while.

Sorry... HS means "hors service" in french... That is to say R2011 is dead... Best regards, Ludovic - F5PBG.

tnx for your info , ill try to check by dummy load as soon as possible , 73 by is0aga...

Sounds like an R.F. feedback issue, more than likely into the power supply or microphone cable. Try and substitute a known good 50 OHM dummy load in temporary place of your antenna system, and I

hi guys , i have a strange problem in 80m when push ptt full or about middle pwr the radio change band automatically for example 20m or change operative mode , practically goes crazy, only in 80m this

Hi, HS may refer to HS Electronic Ltd, a major supplier of SMD and other reeled components in China. Roger, G4PUM Sent: 14 December 2013 04:50 To: ic7000@... Subject: Re:

I don't know what HS stands for, but I assume the resistor was discolored due to overheating. I wouldn't recommend using the DIP leaded caps, as you will probably end up ruining the circuit board

What HS means? I've read over the net cases where this resistor remains intact. I'll begin with the capacitors. ? I guess I have some 100uF tantalum DIP capacitors around.? (for stats) Not available

Yes, it is a classic failure : http://radioamateur.forumsactifs.com/t1516-ic7000-clic-de-relais-a-l-allumage-mais-le-poste-reste-eteint (use Google translate) => Change C501 and C502 (even if

To clarify, C501 & C502 are on the Display board, not the Main board. Getting to the display board isn't too difficult. Just don't lose the little button that sits on top of the Headphone/Speaker

Hello there! I have a 7k with the “click-click no power” problem. I’ve found a good start about it here: http://www.s21rc.net/?p=49 Tested for the C501 and C502 in the main panel board

I can live with the monochrome (though the colour screen of the IC-7000 looks great), but the sloped front panel would be a deal breaker for the mobile station (would slope the wrong way). Useable in
