Yep, the Sirio specs say it can handle up to 900W CW for a "short time", but I wonder if it was around power for a particularly long overs. Seems unlikely to put so much power into an ML145, but who knows. Maybe it's a different fault or I've missed something. I'll see if I can get it apart to be sure it's not the coil or cap. Cheers.

They weren't bad at all when running right, but a HF set is better for the money today imo. Statistics: Posted by Transwarp — 09 May 2024, 22:41 ..read more

Had a 2970 DX-150 since new in 2007. Same digit size throughout. Solid performer. For mobile it dispensed the need for any further "help" so to speak and coupled with a 575-m6 and a megawatt 4k I had many a happy DX pedition. I have a faint memory of the FM issue but I rarely used FM so not an issue afaic. Since 2007 there was the N N2 and more it seems, no idea what they are like. If I was being pedantic about the design, id say the knobs and control were too close together for sausage fingers but I'd buy another, so there's that.

300W is no biggie for that antenna. Chris Statistics: Posted by ch25 — 09 May 2024, 15:33 ..read more

Thanks, Chris. In my experience, it's perhaps 2-3 ohms for a DC grounded antenna, but of course it all depends on the specific design which is why I was seeing if anyone measures zero or a few ohms. It's not an exhaustive test, but I am not sure if it's possible to open an ML 145 to check for certain. It has a nut of sorts at the tapered end, but it doesn't seem to want to budge. Anyone managed to get one open? The original magnetic base is completely fine. I found the RG58 had its centre core detached inside when I first checked it, but even after I re-soldered it on the SWR stayed high. The ..read more

FM receive was awful on the ones l had and SSB was off frequencies on TX, all sorted when sent off for aligning. They may have got better on subsequent revisions / better QC before leaving the production line, the ones l had were pre e-chip models with all same size digits readout.

If you buy a brand new 2950 / 2970 that's straight from a supplier they need to be aligned and tuned, untouched from the manufacturer they are rubbish. It depends I suppose. I've had a few untouched 2950's over the years. Some have been better than others. The one I have now I've had since new. I only opened the bottom lid to do the expansion mod with the plug in dongle thing which came in the box. Nothing else was touched. It's by far the best 2950 I've owned/used. If it wasn't It's doubtful I'd still own it. Statistics: Posted by astradyne — 09 May 2024, 09:03 ..read more

In ML145 coil is shorted for DC and that's the way it supposed to be. DMM should show 0. Problem is elsewhere. Most probably magnet base, which should be original CTE. Also if you opened magnet base pay attention to put it back correct orientation. Shield connector should be on proper "hole" Chris Statistics: Posted by ch25 — 09 May 2024, 07:01 ..read more

Hi, Just measuring the base input of an acquired ML 145 and as it's DC grounded I expected it to measure almost a short, but it's pretty much zero. Does anyone have a known working ML 145 on which they could measure the input resistance (without the mount/mag mount and cable) to give me an idea of the low resistance I should expect. I am getting a SWR quite a bit over 3 (where I would expect 4 to be) and I am thinking the coil may have a short. Thanks Statistics: Posted by Phuture — 08 May 2024, 22:30 ..read more

Hi all I have a few more back in stock now and can program pagers again. Only downside is the pagers are more expensive now and it might Be to pricey to continue Each pager holds 16 stations but your only Get local ones within say 20-40 miles, and your get the requests to launch and the paging crew ones The total cost is over £200 unfortunately as the pagers that are compatible are rare and have to come from Taiwan. PM if you need pics and videos of the pager working and any questions. Sent you a pm if you could include a video of the paget working that would be great . Thanks for your ..read more
