Re: No transmit function on 2M

Re: No transmit function on 2M
Great news, I fixed mine when I got the radio from a seller from eBay, like I said, he said it was working fine, but it wasn't, I had a old parts ft817 so I removed it from there, I am getting fed up

Re: No transmit function on 2M
Good evening 2E0DMB Well in the end it was D3003. I replaced it and it started again. To disassemble the PA board, it is better to first disassemble the main unit because there are pins connecting the

Re: No transmit function on 2M
Hi the bad thing with mine was I had just got it from eBay, obviously the seller said it was in perfect condition, I could have sent it back, under eBays contract, but it was a good price with a tuner

Re: No transmit function on 2M
Hello and thank you for your response. I studied the schematic this morning and came to the same conclusion, it can only be D3003 or D3005. I located them on the layout and I have to remove the plate

Re: Solar panels
Hi John, You are after rather more power than I am, but because I am walking, the amount of time for the panels to be out of the pack and charging the radio is very limited. (1hr every second day) It

Re: Solar panels
Are you looking for specifically folding/portable? There are plenty of small/affordable panels available. Try to avoid amorphic unless it's a newer tech. You tend to get much better power per inch out

Re: Loosening tight screws
Hot soldering iron tip pressed into the screw can work too, if you need good localization of heat.

Re: Loosening tight screws
Hi Rich, Another trick (other than using the correct JIS driver of course) is to give the screw a slight nip in the clockwise (tightening) direction prior to trying to extract it. 73….Eric

Re: Loosening tight screws

Beat me to the punch, Neil! Thanks for informing the 817 group about JIT screws. I found out about them "rather _in_elegantly" back in the 70's when doing consumer electronics repairs. I have since
