[AMRadio] Heath tubes
Does anyone have NOS tubes or recent tubes for the HR-10 RX by heath. Basically I think I need a 6X4 and 2 6BE8's to start with to clean things up. When I turn up my RF gain the frequency shifts. The RF gain is going to ground via the cathode of the first 6BE8 in the circuit. 73, Alan VY2WU __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net

Re: [AMRadio] Heath tubes
Alan: I have a friend whose HR-10B does the same thing. A new tube may not fix the problem. We have speculated that the voltage regulator for the converter tube might not be stable enough or changeing the gain control setting may cause the load to the HF oscillator to shift which would indicate the need for a buffer between oscillator and mixer. Again this is just speculation but I would expect this low cost receiver to shift a bit. My Drake 2C does the same thing but only when I turn up or down the volume! Not the same circuit but similiar results. Good luck.

[AMRadio] 10m AM Calling frequencies?
The band is just too dead to monitor 10m with only my Gonset G28 :-( I have 5 memories to program on my htx-10 a 10m all mode xcvr. 29.0 is a known AM calling frequency. Any others? So far I have programmed 28.2 IARU cw beacons 28.4 ssb calling 29.0 am calling 29.6 fm calling Do I have them correct? Any 10m cw calling freq? bob...w2ami x wn2ami 1962 FN31ar __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
Re: [AMRadio] 10m AM Calling frequencies?
10 meter SSB portion was alive all day(10/28) with many signals. Lots and lots of DX and U. S. stations. 10 meter AM dead.

[AMRadio] 10 meter frequencies
It sounds like you have the voice frequencies covered well. One possible cw frequency is 28.060. That's the QRP operating frequency. Those of us who operate qrp will often call cq there just to test the propagation. Most of the other cw is in the first 25 khz of the band unless there is a contest.

[AMRadio] 15 10 meters
Ever wondered how a contest will cause the bands to open for the duration of the event, then immediately die again? Excluding 6 meters, you rarely see the bands dead during a contest, and full of life afterwards. As was mentioned in another post, both 15 and 10 were open today. Judging by the strength of the ssb signals into Mississippi, AM would have probably been marginal at best. However, I suspect some good AM contacts could have occurred on 15 if we could have plowed through the piles of contesters. I'll try to monitor 21.425 as much as possible on Sunday just in case any AM appears. Then, I'll move up the band if necessary. How's that for optimism?
