I can't answer your SDRPlay questions... Just be aware there are 3 current versions of the MFJ-1708...? ?The base 1708 is a true T/R Switch for old boat anchor rigs...? I don't think you want that

I bought DL5AL’s OPC-1443 alternative separation kit in May 2021 for 50 Euros. Attached is the manual. If I needed another, I’d buy one from him again. Contact him for one. https://dm5al.de/

Any updates on the opc-1443 or a substitute? Thomas McCainKC5ETW

Has anyone used the MFJ-1708 T/R switch and a SDR with the IC7000?? Also were they able to control the radio thru SDRPlay?

Hi I have ordered a new UHF fet, it should be with me in about 2weeks time, I will let you all know when it arrives and I have fitted it, I hope it will not be a fake, Thanks all for your help Thanks

I agree with Steve. When you can not get 2.5 Ampere with UHF Adj, you have UHF mosfet with any issue. You can get power (often 15-25 watt….) but you need to fix with new mosfet RD60HUF. 73s

Hi Steve Thanks for the info, Like I said I am getting full output power now, but the data sheet does say it is a 60w item, so that is probably why I am still seeing 35w, but I do want it as it should

Dave, The UHF Idle Current definitely needs to be set to 2.5 amps for minimum distortion and spurious emissions.? I would suggest replacing the UHF PA FET.? There are other possible causes, but

Hi Steve All the bands are now set to output power as specified, But as I could not set the 430mhz final Ideal current to 2.5amp above the 00 setting, as I could only get 400ma over, but I am now

Hi Steve Yes I have just realised what I was doing was incorrect, I have just done it correctly, I could not get the 430m final ideal current to 2.5a above the 00 , reading, I could only get it 400ma

Dave, Set the Driver Idle Current adjustment reading to "00", then note the current draw.? Rotate the? dial to INCREASE the current draw by 1.0 amp above the previous reading.? That establishes

Hi, in the adjustment menu i can not get the driver idle current down to the 1 amp setting? the lowest it will go to is 2.56 amps but it could be some leakage on any of the other output transistors

Are there any variable caps in the TX lineup that MIGHT be touched up to equalize the output across the whole band? VERY small adjustments to avoid screwing EVERYTHING up if you mess with it! 73 -

Hi what power are users getting out of there radios on uhf, are they seeing 35w as per icom specs, Thanks Dave 2E0DMB

Thanks ,I always like updates, some times I read a load of posts on forums, and then I do not find out what has happened, There was a lot of good ideas, so I had to let all know how it went, Thanks

Well Done!!! Thanks for the updates. Hoffy - VK4OY

Hi have not done the driver heatsink compound yet, but i have now got the remote socket working correctly and i can put the radio into Adjust Mode, Thanks for all of your help and ideas, Thanks Dave
