Paul,

I scanned the two pages of the PL-368 manual which explain the ETM function and have attached them here. It is the same as the PL-330 ETM and I have attached that entire manual for other details, many of which are the same. Recent Tecsuns share many similarities so this should give you the info you want.

I just got my PL-368 and will write it up fully after a few weeks of testing and comparisons.

Let me know if I can provide any more info...my review is in progress.

Wow, your scans are much better than mine. Would you scan pages 1-5 showing the keys and display?  Thanks

You are fast, Jay.  I had just scanned the page too but you beat me to the upload.  Good job.  Looking forward to your review.

Re: Common Interference Sources

Well after spending some time over the long weekend on this, I have tracked down the source to be our dishwasher, specifically when it is first turned on and is running. I have checked this the last few nights and confirmed it via two radios.

Strange Band Behaviour

Paul Blundell
 

Over the long weekend, I have noticed some strange behaviour of the HPON station on 1593kHz. During one of my long term DX project sessions I was tuning past this station and thought I had scrolled too far (to our local 1611kHz sports station) as the signal was so strong. Below is a break down of some stations at both ends of the band that are all 5kw and around the same distance (I have included the 50kw station for reference).

531kHz (3GG) = 384km - 5kw (3,3,4,4,5,3) 22
594kHz (3WV)= 679km - 50kw (4,4,5,5,5,4) 27
1503kHz (3KND) = 445km - 5kw (1,2,1,3,3,2) 12
1566kHz (3NE) = 572km - 5kw (2,2,3,3,4,3) 17
1593kHz (HPON) = 459km - 5kw (4,4,4,5,5,3) 25

What I am seeing is that this station is performing at a level which is much beyond what I would expect. I normally expect that the stations at the lower end of the band will put out a better signal and normally be received "better", when compared to stations at the top end of the band which are the same distance away and transmitting the same power level.

Good work, sometimes you just need to give things a try and see how they work (or don't work).

I have a problem: when my radio room was in the front of the house (on the east side), it was easy to run a feedline to a large RF-hungry SWL dipole with various stubs and feeders.

Monitoring VHF/UHF is no big deal because of high-performance scanner antennas. HF, however, presents challenges. My main receiver is a Satellit 800, which has the guts of a Drake R8 but also has a large telescoping vertical antenna. It works okay, but I wanted more signal.

I've been looking at small loops and got some great recommendations on another thread, but then I had a thought: what if I turned the 8' x 12' room into a giant horizontal passive horizontal loop?

So I called a ham friend and ran the idea by him. Sure, he said, give it a try. He gave me 25 feet of 4-conductor phone wire. The better half helped me to strip it. I ran a single strand -- about 50 feet long -- around the perimeter and hooked the ends to the clip-in terminals on the back of the Satellit 800.

There's a switch on the back of the 800 that allows me to quickly compare the loop with the radio's built-in vertical antenna. And . . . it works! It pulls in more signal than the vertical, but there is not noticeably less noise on the higher bands -- 15 megs and above.

Tomorrow, I'll be checking the lower bands early, but so far, so good. I did check and it seems to work well on the lower bands as well.

Re: CCrane CCSkywave vs CCRadio2E (Warning! Informal Rookie Testing!)

Hi Jay,

Thanks!  Very helpful!

I had not considered some of what you have written.  I will take these factors into account as much as possible next time I do my testing.  Great points. 


Johnny


Re: CCrane CCSkywave vs CCRadio2E (Warning! Informal Rookie Testing!)

radiojayallen
 

I have found that the main reason for different results like this is that local conditions are often the limiting factor in reception and mask the differences in the radios. For example, if the noise floor is too high you can’t hear the difference between a radio with an excellent RF dynamic range and one with a higher noise floor. Also, AM/SW sensitivity is best measured in a low noise environment midday when signals are weakest. At night with many stronger signals, it is much harder to see differences in many radios. It is also good to understand that RFI is not always audible as such…sometimes you may or may not hear outright buzzing or whistling but the radio will be desensitized overall. In my own house some locations are much more revealing of differences in radios…in other parts of the house they all seem about the same…understanding this is key.

In order to more accurately assess how radios compare it is essential to be sure local conditions are not the limiting factor.

Certainly appreciate more controlled methodical testing (e.g. Jay Allen) but I find these these field observations to be very interesting too.

For one, it emphasizes that overall performance differences between some models can be really very small until you dig more deeply.

Second, always the possibilite influence of sample-to-sample variation especially in factory alignment and the impact on receive sensitivity.

Hi Larry,

I will absolutely let you know, I may get one in the next few weeks.

I will be careful to not "imagine" that it is better than the Skywave, because it costs double!  ;)
