Do you know where I could find a copy of the Ham Brew article? Is it on the
web someplace, or does Dan's include instructions? I didn't think of Ten-Tec -- when I hear Ten-Tec I think "really expensive American made radio", not "good cheap kit". That is my problem and no one else's, of course. "Howard" wrote in message om... "Keyboard In The Wilderness" wrote in message news:21ANb.23933$zs4.10105@fed1read01... Lots of kits and projects at URL: http://ac6v.com/kits.htm Here is some info that may be of interest: IMPROVED NEOPHYTE RECEIVER This receiver was featured in the spring 1994 issue of Ham Brew Magazine Designed by Wes Baden, K6EIL This is a nice 40 meter receiver and uses a NE602AN OR NE612AN mixer chip and incorporating an AF pre-amplifier and bandpass audio filter will drive a 2 1/2" to 3" speaker to room level volume. Kit includes etched circuit board and all board mount components included is a very nice 20pf air vairable capactior..double bearing type has built in 8:1 reduction and 1/4" shaft copy if artical included with kit...price of this kit is...$32.95 You can find the site where this is offered by doing a Google search of "Dans Small Parts and Kits." Ten-Tec also has a kit in their T-Kit series that sells for $29.95 and comes with all of the parts to put it on any band from 80 thru 10, and this also has an audio filter that works quite well. The Ten-Tec also has a very fine instruction manual, so that would seem to be a better kit for a kid. Hope this is of some help. 73 de WA2AFD |

I didn't think of Ten-Tec -- when I hear Ten-Tec I think "really expensive
American made radio", not "good cheap kit". That is my problem and no one else's, of course. That is what I usually think also. I did put together their 6 to 20 meter transverter several years ago and it seemed to work fine for me. Receiver converter part was very sensitive and I received good audio reports from it using a Yaesu 757 lowband rig. |

Receiver converter part was very sensitive and I received good audio reports from it using a Yaesu 757 lowband rig. ================================= Question : Is the Ten-Tec 6m transverter also available for 28 MHz e.g. RX : 50 -- 28 MHz ; TX : 28 --- 50 MHz or can the 14 to 50 MHz transverter be readily modified for operation from a 28 MHz base unit ? Reason for the above question : I have an old (but almost unused) Yaesu FT901DM HF transceiver with a FTV901R transverter with 2m and 70cms modules but without a 6 m module. The system works through the HF transceiver's 28 - 30 MHz band . In Europe the 6m band is from 50 - 52 MHz. TIA for any advice. Frank GM0CSZ / KN6WH based in Scotland. |

The system works through the HF transceiver's 28 - 30 MHz band . In Europe the 6m band is from 50 - 52 MHz. The 20 to 6 meter converter is made to operate in the low end of 6 meters. The US band is 50 to 54 mhz but TT does not recommend operating much above 52 mhz with their transverter. They do make a 2 meter to 6 meter transverter so you could run you equipment and feed it to the trtansverter to get on 6 that way. Converting from 10 meters to 6 meters is not done very often as it is difficult to keep the 2nd harmonic of 10 meters out of the 6 meter output. By changing crystals and a few tuned circuits I don;t see why you could not make the converter work with a 10 meter rig. It might be difficult to filter out the 10 meter signal. Go here and look at their products. http://www.tentec.com/ I was having trouble reducing the lowband rig output to 5 to 10 watts needed by the transverter. I finally designed a hard keying circuit and also bypassed part of the transverter padding and fed the low level (milliwat) signal into the transverter. It worked fine by doing that and no worries about blowing out the backend of the transverter. 73 de ku4pt |

The Ten-Tec 20M--6M converter can be easily modified to 10M--6M. I have done that and it works fine. Essentially, you change the LO in the transverter to 2 selectable LO's - one at 22 MHz, the second at 24 22 + 28 = 50; 22 + 29 = 51 24 + 28 = 52; 24 + 29 = 53 You need 2 xtals and a few components to change the bandpass filter after the LO to 22-24 MHz The xtals can be selected via relay or diode switching. With a simple homebrew outboard filter, the thing is pretty clean, according to a friend. I never used the filter or put mine on a spectrum analyzer, so the cleanness of the signal is hearsay. |
