Tenna Dipper, part II...
 
|
Now That I have finished my basic Tenna Dipper Kit. I need to put it
in an enclosure with a little bit bigger switches, buttons.... BUT, BUT... one thing.... In this kit, if you need to know the frequency that the Tenna Dipper is, you could just listen to the CW tones, but you will not be able to know too easely at which frequency you are..... very anoying... :-( Why do not make an external connector on the K2 that is link to the frequency counter probe connector on the control panel. After you have selected the CAL FCTR function, connecting the Tenna Dipper External frequency test point to the K2... you will be able to use your K2 to display the actual frequency of this little antenna anylizer.... and now be able to use more easly the Tenna Dipper on many different frequencies instead of using it always at a pre- defined frequency, because it is too hard without proper external indication. What an idea ???!!!! Let me guess.... I will do it tomorrow !! I let you know "by picture" as soon as possible. 73 ============================================= /¯\/¯\/¯\/¯\/¯\/¯\ JEAN-FRANCOIS MENARD V A 2 V Y Z [hidden email] \_/\_/\_/\_/\_/\_/ Elecraft K2 #4130 Elecraft KX1 #999 http://homepage.mac.com/jfmenard ============================================= _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Jean-Francios,
It is quite possible to use the internal counter (CAL FCTR) for external measurement - just don't forget that the ground must be connected to the Device Under Test too - the normal K2 counter probe does not connect the ground at the probe end when measuring inside the K2 because the ground is continuous inside the K2 - and external probe would need a ground (similar to a 'scope probe ground). I had had many thoughts about providing a connector on the left side panel that would accept an external probe, but I acquired an accurate frequency counter before I got around to implementing that 'feature'. 73, Don W3FPR > -----Original Message----- > > Now That I have finished my basic Tenna Dipper Kit.

I'd agree that the Tenna Dipper is a simple, inexpensive alternative
to the antenna analyzer. Another simple and inexpensive alternative is an antenna noise bridge of the type that uses the transceiver itself as the frequency determining element. These gadgets are broad- banded so they cover the whole HF spectrum continuously. Palomar Enginners, Heathkit, MFJ, and perhaps others made them. Ten Tec sells one in kit form for $19: See: http://radio.tentec.com/kits/Accessory I found another kit at : http://www.qrpp-i.com/KA8MAV_NEQRP_NoiseBridgeKit_Review.htm Dick, K0KK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Small Wonder Labs also has a noise bridge available, $17 < http://www.smallwonderlabs.com/noisebrg.htm > 73 de dave ab9ca Lambs, Dick & Judy wrote: > > I found another kit at : > > http://www.qrpp-i.com/KA8MAV_NEQRP_NoiseBridgeKit_Review.htm > > Dick, K0KK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

In reply to this post by JEAN-FRANCOIS MENARD-3
There is also the KD1JV digital frequency counter kit that could be used
to modify your Tenna Dipper, so that it has a digital LED for the frequency. http://www.qsl.net/kd1jv/Ddial.HTM I don't have either kit, yet. Has anyone tried adding the KD1JV frequency counter kit to the Tenna Dipper? 73, - Rob KE7EAG K2 #5004 (under construction) On Tue, 27 Sep 2005 16:06:48 -0700, JEAN-FRANCOIS MENARD <[hidden email]> wrote: > Now That I have finished my basic Tenna Dipper Kit.
