I've had a chance to tinker with the VT-111 and test it at night. I have some noteworthy observations about this set.

1.) No bleed-over channel-to-channel 1080/1090 kHz for example is good... no bleed from 50kW 1080 local (35km) on 1090 400km.
2.) With the bar outside the set, the iBOC is diminished.
3.) Subject to deep fading w/o a loop.
4.) Unusual for a DSP... tune to a station, and let it sit there 1 or 2 minutes.
Apparantly the the set "tunes" the various factors for RX. Stuff I thought was dead, was not: it actually RX'd quite nicely when allowed to "tune itself".

Other OT stuff of note. I ordered a Tecsun R9012 as my R-911 of 7 years finally is having trouble with the band switch (loose and not a good CNXN). The knob on the 9012 is a pleasure and is not as stiff as the wheel of the R-911. The old set returned to box for storage. /OT

Oregon Cliff (Rockwork 4) Ultralight DU's for 7-6

Gary DeBock
 

What started off as a pretty mediocre session ended up with a turbo boost in Kiwi propagation, resulting in one of the wackiest ocean cliff mornings in recent memory. It was almost like someone turned on a switch at 1220, giving every New Zealand station on the band a serious energy surge. The exotic Kiwis on 576, 585 and 936 suddenly came out of the noise to reach respectable levels, after having been MIA since the start of the trip. The only problem was that there wasn't enough time to go after all of them before the wacky propagation collapsed around 1300.
 
Although the "sleeping squatters" left Rockwork 4 alone this morning it seemed like exotic DX would do the same-- at least for the first hour of the session. Four mega-FSL's were all set up and ready to record, but Longwave from the South Pacific was again dead, and only the Kiwi big guns had any readability on MW (and even they were sounding anemic). High priority frequencies like 558 and 729 were barely registering carriers, and as if to rub it in some splatter from a domestic 530-TIS station was dominating 531. Suddenly around 1220 the Kiwis seemed to get a resurrection call, with Tony W.'s 684-Rhema suddenly coming up out of the KNBR splatter to sound pretty healthy at 1231. The NZ big guns on 702, 1035 and 1386 started pounding in at awesome strength, and a check of the rare 936-Chinese Voice (1 kW) at 1243 found it with music and speech at a decent level. The Rare Kiwi rush was on, but checking the parallels for low power stations like 576-Star and 585-Radio Ngati Porou takes time, and time was running out on sunrise enhancement. 576 (the "Dwarf Star") and 585 were logged for the first time on this trip, but by 1250 the Kiwi turbo boost was starting to collapse, and only 738-Tahiti was holding up at a potent level. 702-Magic, 1035-Newstalk ZB and 1386-Radio Tarana managed their best-ever signals for me during this freakish surge, which would have been legendary if it had continued throughout the entire session.
 
531   PI   Auckland, NZ   Good-level Samoan male and female speech at 1205 (with trace of 4KZ underneath). This frequency seems to have its own special propagation, often running contrary to the rest of the MW band (there was no Kiwi propagation surge) 
          
684   Rhema   Gisborne, NZ   Sounding pretty healthy (despite an impending eviction order) with Christian contemporary music // 594 at 1231
 
702   Magic   Auckland, NZ   Best-ever strength with oldies music during Kiwi propagation surge at 1240
 
738   Radio Polynesie   Mahina, Tahiti   Participating in the Kiwi propagation boost with potent jazz music just prior to the 1300 TOH
 
765   Radio Kahungunu   Napier-Hastins, NZ   Strong Maori music from this 2.5 kW station  // 603 at 1218
 
936   Chinese Voice   Auckland, NZ   Rare 1 kW Kiwi was a major beneficiary of NZ turbo boost with good-level music and speech at 1243
 
1035   Newstalk ZB   Wellington, NZ   Best-ever strength with NW political talk show during start of Kiwi turbo boost at 1225
 
1386   Radio Tarana   Auckland, NZ   Another Kiwi big gun with best-ever strength, pounding in with S9 level Hindu music at 1246

Oregon Cliff (Rockwork 4) Ultralight DU's for 7-5

Gary DeBock
 

A bizarre collection of monster FSL antennas crossed the bridge into Oregon at the wacky hour of 0145, after having been crammed into an overloaded Toyota Corolla for a one week trip. As such, the July 2016 Rockwork 4 International DXpedition kicked off with an early start (most of the participants, including Japanese DXers Hiroo Nakagawa and Satoshi Miyauchi, will arrive later this week).
  
As is common at this wacky ocean side cliff (notorious for Murphy's Law), a "sleeping squatter" occupied my usual antenna setup space, but four huge FSL antennas were deployed anyway at the northern edge of the turnoff. One FSL was used to record 531 kHz, two were used for South Pacific MW-DX reception and the fourth was used for Longwave (which unfortunately was a propagation dud from the South Pacific this morning). After the recent demise of Vancouver "traffic" 729 was also a prime target, but it failed to cooperate. The session was fairly good for New Zealand reception, although the really exotic Kiwis on 531, 576, 585 and 936 stayed down in the noise. A couple of Australian big guns (531-4KZ and 774-3LO) managed decent signals in and out, although others on 576, 702 and 891 were missing in action. 567-RNZ seems to have demolished most of its signal along with its old tower-- it's now running a poor second to 675-Christchurch as the RNZ flagship. Stars of the session were 531-PI with potent Samoan speech for most of sunrise enhancement, and 603-Waatea with a 25-minute run of beautiful Maori music from 1206-1231.
 
531   PI   Auckland, NZ   Strong female Samoan speech at 1214; trace of 4KZ underneath at end
 
531   Innisfail, Australia   Pop music fighting it out with PI throughout session; the usual ID jingle at 1209
 
603   Radio Waatea   Vibrant Maori music at 1226; part of 25 minute potent run
More beautiful Maori music at 1230
 
657   Star   Wellington/ Tauranga, NZ   Christian music at decent level // much weaker 963 at 1232
 
675   RNZ   Christchurch, NZ   Strongest RNZ outlet after the demise of 567's old tower; good level Kiwi English speech at 1257
 
738   Radio Polynesie   Mahina, Tahiti   The usual African music at a potent level at 1251
 
765   Radio Kahungunu   Napier-Hastings, NZ   Maori male speech // 603 at 1229; not a bad signal for 2.5 kW
 
774   3LO   Melbourne, Australia   The strongest Oz station this morning, // a much weaker 828. The usual ABC network interview at 1222
 
792   Radio Sport   Hamilton, NZ   "Fox Sports Radio" ID (as relayed by Radio Sport after local midnight) with promo at 1220
 
1503   Radio Sport   Wellington/ Christchurch, NZ   Fox Sports Radio ad with Yankee English accent // 792 at 1244

The PAR antenna probably uses a 9:1 unun so it may match well with that radio.  The only way to know if it would overload the radio is to try it.  I make all of my baluns and ununs...very easy...and for receive only baluns or ununs I use alligator clips so I can always unclip the thing and use just the long wire if it overloads, if it still does I unclip that and use the telescoping antenna.  I rarely use the antenna jack if the radio has one and just clip the lead to the base of the telescoping antenna.  The VITE doesn't have an antenna jack but some of the radios I have do.

THANKS FOR THE REPLY.  I WILL TRY THE ANTENNA  AND REPORT HOW IT WORKS.  I HAVE BEEN USING A SHORT WIRE WITH ALLIGATOR CLIPS ATTACHED TO THE
 
CENTER PRONG OF THE COAX AND TO THE WHIP ANTENNA, WHERE THE RECEIVER HAS NO ANTENNA PORT LIKE THE VTE VT 111.

These are nice end-fed antennas. Usually, they are matched to a specific Amateur band. I guess it could work OK on the off-bands such as SW.

For AM/LW attatchment would be to the ferrite bar antenna, either direct or loop-inductive link.

Folks,

I wonder if an outdoor PAR EF SWl   antenna attached to the whip would overload this receiver.  Does not overload the Tecsun 390 or the Kaito 1103  portables.
 
Anyone have an idea about this on the VITE VT- 111. I would like to use this receiver for MW  LW   SWL Work.

Thanks for the reply Paul. The original inside Loopstick is so bad that on our local sports radio (1290 kHz) I can hear squealing. Its unfortunate because the radio itself with all its great digital features even has Longwave Band capability when MW Button is pressed twice.
Question - how did you and Ryan secure the original Loopstick to the outside of the radio? i.e. did you reglue it to the back of the outside of the radio?

I have the ferrite bar just sitting outside the radio (using kickstand) as far as the wiring allows. I did not attatch it to the case at all.It needs to be a few inches away from the radio. The closer to the set, the more noise there is.

Re: VITE VT-111 ordered

Yes Jerry, thats the idea. Remove the ferrite AM antenna bar and wiring from the radio so its external.

This mod passed a rather important (to me, anyways) test. 550 WGR in Buffalo, NY is about 300 miles at 5kW. Compared to WKBW on 1520kHz its rather weak at night. Well all of the Tecsun DSP's I've had are loaded with digi-noise, and do not receive WGR... just noise. The Sangean ATS405 has the soft-mute off by default (it can be enabled). That radio receives WGR. Last night for giggles I tried the modified VT111, and it too received WGR, with some local noise (not internal). Fair copy here in Central Conn. WGR is running ESPN sports, and Freddie was on at the time. So for $14 and a little elbow grease, it did almost as well as the $85 Sangean, and better than the Tecsun DSP's, and did better than a R911 and R9012 using a Loop (9") at a similar price of $15-20.

Once afgain, a tip of the radio cap to Ryan for breaking open the case, this is a good mod.

Re: VITE VT-111 ordered

Good job on the writeup Paul. I guess you are saying to remove the entire Loopstick  outside of the radio case for better reception? 

Also for those wishing to see a video of the actual inside of the VT-111 and the yellow wire Paul is talking about see: Потрошки VITE VT-111 HAM Radio Channel

I replaced the pdf version of the modification with a text file. The file is in a VT111 folder. Unfortunately, the responses did not say which of the files was generating an error or format error.. The version in the 6.) file was removed completely. There's a problem with uploading to yahoo, it wants double-clicks sometimes, and other times single clicks. Not very friendly.

I realize that all pdf readers are not equal.
