The bootloader problem at the end of my video was MY fault. Firmware 2.29 is now flashed to my LP-500. With the next firmware upgrade I demonstrate the process and what I have done wrong! It is really easy....

Thanks for the nice review Peter, I'm looking at both items for my shack. I appreciate that you have a 'steady' mount for your camera and good microphone placement for good audio pickup. Your videos have always been informative, for some they may not fit the 'I'm in a rush, get on with it' impatient folks, don't let them bother you, your pace is fine :)

Thanks Peter for the review. I imagine you probably didn't "take it apart" but I was wondering why there is a plastic or rubber plug on the top cover where you'd expect the fourth screw to be placed (left front). Also, can you set the peak hold function to actually hold on the highest peak? The way it appears to work is that the peak hold indicator on the bar display remains momentarily and then moves downward for example to a reflect a lower peak. I would think the peak hold would indicate the highest peak until perhaps you manually cleared it for further measurements. I hadn't really noticed that before but that's the way it works on the LPA100 as well. Small issues but curious. 73 - Dino KL0S

BTW, the other thing I noticed was that the front panel control knob appears to cover the silk screen label for the knob.
@TRXLab7 жыл бұрын
Hi Dino, yes I have seen the plastic plug as well, seems to be a kind of warranty seal I believe. In the menu you can adjust the peak hold time and then it appears that it holds this peak until you release the PTT or a higher peak arrives. In my unit the peak hold time is adjusted to 0,5 s. May be a bit to short.

Hi Peter, You may want to correct your math in minute 56. Each peak has less than 1/10 of power your are speaking about because modulation two tone signal is about 10dB weaker than 200Hz sub-carrier as you show in minute 42. Therefore spectrum shows IMD products radio generates in SSB mode when driven by two tone signal to less than 10W PEP, not 100W. At 100W it would be different, usually much worse. 100W PEP value shown in lower right corner is bit misleading as is generated by sub-carrier which has very low contribution to shown IMD products and is filtered from display. Otherwise nice video, thank you. regards Joe
@TRXLab7 жыл бұрын
Joe, okay let's discuss it this way. The LP500 is a very accurate test device and from this perspective lets approach the reading. Don't ever let you confuse by the algorithmic which is needed to get the meter doing what it should. In minute 51:40 you see that the setting is put to 55dbm max. That means that the zero line is full power = 55dbm. On 55:36 you see the both fundamentals on -11dbc That means it is 55dBm-11dBm= 44dBm. And we can agree that 44 dBm is 25 watt per tone. As we have 2 tones that means we have 50 watt on average power thus it is 100 watt PEP output. And trust me the radio was set to full HF power and it was transmitting with 100W PEP. In video#42 you can find the answer how it hangs together if you like. Thanks for watching and comment . 73
@joeorange93917 жыл бұрын
Thank you for response Peter. Unfortunately you are missing point, probably because I wasn't exact and my initial figures were rough. So lets do math again exactly. In spectrum mode you set output of your radio to 100W (99W to be exact). It is 50dBm, not 55dBm. 55dBm is 316W ... Actually, LP-500 shows 99W/49dBm. 49dBm is 79W but it is probably error of truncating decimals instead of rounding. Let's not hair pick there ... Assume that 100W/50dBm is set as zero reference, both fundamentals are -11db lower what is 50dBm - 11dB = 39dBm. 39dBm is 7.9W. So two tone signal has 2*7.9W average power, 31.6W PEP. Rest to shown power 99W, exactly 67.4W (99W - 31.6W) is hidden in the sub-carrier. Therefore IMD products obtained as difference between two tone fundamental levels and their IM3 siblings do not provide correct IMD figures as if radio was driven by pure two tone signal to 100W PEP, radio is driven by two tone signal only to 31.6W PEP output power and by sub-carrier to 67.4W PEP. So algorithmic matters a lot. I'm not confused and understand that sub-carrier must be there to pass two tone signals in SSB mode through simple envelope detectors originally invented for AM detection, not SSB. Results obtained in Spectrum mode need to be properly interpreted to not make bad conclusion whether radio generates clean or dirty signal. There is no 50W PEP power in each tone but only 15.8W, and that's an error I wanted to highlight in your otherwise very nice video. Thanks for reading. Merry Christmas Joe

Joe, nothing wrong with your math BUT LP500's reference zero line is 55dBm! I f you would do your calculation with this setting... Other than that all is fine :^) Merry Christmas Peter

Hi Peter, You are right, according to LP-500 manual, reference can be set to 45/55/65dBm. Seems spectrum amplitudes are intentionaly manipulated to hide drawback of used sub-carrier algorithmic. Bummer ... regards Joe
