New Trans Continental Distance Personal Best (MILES PER WATT)

New Transcontinental Personal Best- 

I had to a call a second time to break my personal best with margin (previous best 9800 MPW from NY4G to CE2AWW)

First Call NY4G to HA3NU - Hungary 4982 miles with 1/2 watt or 9964 MPW 0131 UTC
Second Call signed as VY2AJ/W4 to HA3NU - same 4982 miles with 0.4 watt or 12455 MPW 0145 UTC  (VY2AJ is my Canadian Call Sign)

Third Call Signed as NY4G/QRPp to HA3NU - same 4982 miles with 250mW or 19928 miles per watt @ 0154 UTC

HA3NU asked me how much power I was running - I told him 250mW.  He asked me what kind of antenna - I told him dipole at 60 feet.  His comment was that my signal was super steady  - gave me a 559 report

Made it to US Virgin Islands with 1 Watt on 160m CW.   NY4G to NP2J 1621 miles per watt

The previous days resulted  in Intra-Continental Personal Best

NY4G to W2EG 684 miles with 100mW  6840 miles per watt (40m CW)

Tried hard to beat it - but all I got was the following (40m CW)

NY4G to EI5KF 3685 miles with 5W
NY4G to WB8WKQ 542 miles with 100mW 5420 miles per watt
NY4G to W2RR 567 miles 100mW - 5670 miles/watt
NY4G to HB9CVQ 4522 miles 5 Watts
NY4G to K9OM 434 miles 100mW 4340 miles per watt
NY4G to N6AR 456 miles 100mW 4560 miles per watt
NY4G to NA8V 552 miles 100mW 5520 miles per watt
NY4G to LZ1KPO 5354 miles 1 Watt 5354 miles/watt
NY4G to N8OO 636 miles 100mW 6360 miles/watt

Till K1RM came along
NY4G to K1RM 687 miles 100 mW 6870 miles per watt 40m CW

Made it to Ireland with 1 Watt on 80m CW.   NY4G to EI5KF 3685 miles (confirmed in LOTW)

New Ones on 80m and 160m

March 27 Update

QRN was high, then all of a sudden PJ5/SP2GCJ signals went up a tad and noise levels dropped.  I was able to make contact at 0122 UTC on 160m for #118 on 160m

Worked TJ2TT on 80m for #162

March 22 Update

Worked OZ5DX on 80m for #161

March 20th Update

3B8XF Mauritius - Nigel Cawthorne confirmed for #160 on 80m

Also worked 3C0W  and PJ5/SP2GCJ Saba and St Eustatius on 160m.  Without internet can't confirm whether the 3C0W is a good QSO


March 14th Update

80m continues to be a productive band.
#154 3C3W Equatorial Guinea on 03March
#155 Z2LA Zimbabwe on 05 March
#156 XR0YD Easter Island 05 March
#157 TY7C Benin on 09 March
#158 TN5R Republic of the Congo on 10 March
#159 3C0W Annobon 13Mar

On 160m - CU2DX Azores confirmed in LOTW for #115.

Got new ones on 160m
#116 XR0YD - Easter Island
#117 TN5R - Republic of the Congo.    Solar wind effects killed 160m propagation.  It took all kinds of tricks - diversity receive and audio peaking filter to dig the really weak signal out


March 3rd Update

Was able to get 3C3W on 80m CW on the evening of 03March for #154.

3D2EU Rotuma Island DXepedition  is underway - was able to get them on 80m and 160m on consecutive days on the early morning grey line #114 on 160m and #153 on 80m on 27Feb

Receive Antennas at NY4G

Some really interesting references:

http://www.w0btu.com/Beverage_antennas.html#Beverage_On_the_Ground

At NY4G's Station are two reversible beverages on ground (RBOGs).  Both a re 200 feet long. with RG6 feedlines.  These replace the K9AY that I used to have.  These use the KD9SV feedline and reflection transformers.    The antenna switch will be the receive antenna switches from HiZ and the pre-amp for 160m and 80m are from KD9SV


A short video showing the performance of the beverage against the transmit antenna - inverted L.  One can hear that with such a weak signal, on the inverted L, the signal is buried in the noise and indistinguishable.  It is a much better copy on the beverage.


The following video gives an idea of  the front to back ratios between the different directions.  The DX station is 3B8XF in Mauritius some 10000 miles away and the bearing is 75 degrees.  The DX Op is Nigel Cawthorne G3TXF and a very very good CW Op.  The northeast beverage should be the strongest and it is. The inverted L signal is very strong, although the noise is higher, the signal overwhelms the noise.  The F/B ratio is about 12 dB or perhaps a little bit better is my estimate.

New ATNO #309 4B4B Revillagigedo, More New Ones on 80m and 160m

Interesting DXpedition - appears to be only SSB and only one Op.   I was able to make contact on 20m 14.225 on March 6 at 23:39.  This was one of those times where I had to dig for a microphone buried in my junk drawer.  I had to wipe the cobwebs off of it.


80m continues to be a productive band.
#154 3C3W Equatorial Guinea on 03March
#155 Z2LA Zimbabwe on 05 March
