Wolf River Coil SB 1000 Platinum - 213" Whip Antenna Tuning Guide W0DHZ - Dale Henninger

-

 Love my Wolf Rive Coil Antenna for POTA use but I haven’t marked it up (yet) to facilitate quick band changes while out in the field.   Here are some notes to use as a starting point based on the work by W0DHZ Dale Henninger:


102″ Telescoping Whip

BandWhip LengthCoil Position
6mOnly 1st section of whip extendedNo Clicks – Top of Coil
10m3 sections out + 6″ of 4th sectionNo Clicks – Top of Coil
40mAll sections out3 Fingers Down

213″ Telescoping Whip

BandWhip LengthCoil Position
10m8 sections out + 1″ of 9th sectionNo Clicks – Top of Coil
20m9 sections out + 13″ of 10th sectionNo Clicks – Top of Coil
40mAll sections extended16 clicks down






Reminder to subtract the length of the Wolf River Coils SB-1000 coil from the 1/4 Wave lengths above.

Remote CW with RKI 1.05 and Sparkfun FT231X breakout board

-
Image
I've created a workable solution for sending CW via a "straight key" to my remote Flexradio 6600 at the lake using RemoteKeyerInterface (RKI) and a simple Serial/USB circuit.   RKI is only available for Windows. RKI enables you to use paddles or a straight key to send CW through a remote Flex‑6000 transceiver.  After several iterations I've settled on a design using the Sparkfun FT-231x breakout board and RKI v1.05 that was originally posted by Gary KT7AZ on the RKI  groups.io forum .   However, to send CW reliably via a straight key - there were two main problems I had to solve. First,  I had to resolve the network latency and buffer bloat in my shack's network by setting up a router with Smart Queue Management.   The Ubiquity EdgeRouter  was recommended by a friend of mine (Larry N1FG) and has been working great.  I'm using the 4 port Edgerouter X which was only $50 at microcenter (open box special).  No more audio stutterin...

Update 11/19/23 - Tribute for Bill Crane, SK 10/26/23: https://youtu.be/Znyqq9f93r0?si=bxPV0zVmGN7oWo_u ++ Update August 22, 2022.   I was able to find Bill Crane W9ZN on the air by looking for his spots on RBN .   Took me a while to see the pattern on when and where he's be on frequency, but not only did we make the QSO, we exchanged cards as well!  This is one of my favorite QSL cards that I've collected so far.  Thank You Bill!     73 Chris de WX7V ==================================== Last month I asked a members of the Straight Key Century Club  what was their favorite way to warm up before sending morse code.  I got a lot of input - from, "Just jump right in" to sending the Alphabet and the Numbers 0-9.   My favorite answer is to practice sending Bens Best Bent Wire, with the letters and numbers run together so that the code produced sounds similar to a march.  Apparently this was taught by the RAF,  merchan...

FTdx3000 - configuring external panadapter using SDRPlay RSP1A

-
Image
 The panadapter on the FTdx3000 is fine but not great.   I'm using SDRuno with the SDRPlay RSP1A  which is a significant upgrade!   Cost was minimal since I already had a RSP1a stored in a  drawer waiting for a problem to solve.   Hardware configuration is straight forward.  On the back of the FTdx3000, connect the IF OUT (RCA connector) to antenna input on the RSP1a.  I needed a cable with RCA to SMA adapter.  Plug in USB connections from the RSP1a to the computer, and another from the FTdx3000 radio to your computer. Download and install OmniRig from dxatlas.  Omnirig provides CAT control for the Yaesu radio - allowing you to automatically tune into any frequency by clicking signal in panadapter waterfall.   Find the SiliconLabs Enhanced Comm port (use Ports in Device Manager)- you need to use the same com port and speed settings in the omnirig and sdruno configurations. Start sdruno, click on settings - the...
