Sorry, I guess I'm just hopelessly dense, but this follow-up post did nothing to help me understand the first post. Perhaps if you explain it to me like I'm a six year old. Well first, you have to c
Who designed the RX320. IMO, it's a very elegant design and quite a radio for the $. meant my reply for Bob only. still not used to this reply to sender replying to list business See the rx320d for
Consider this. A bunch of guys invested in BPL. The value of their investments was sharply decreased by interference issues. Instead of bailing, they buy up investments from others at a cheap $ and t
It would be kind of fun to mess around with 6kc-10kc bandwidth digital modes. Would take up no more space than the HiFi SSB. HF 16 QAM anyone? Given the high level of concern for broadband SSB shown
<<<I love it when all these people stand up & criticize the Orion. I bet that 75% of the critics have NEVER turned a knob on a Orion.>>> This same situation certainly exists concerning enhanced SSB
Missed your reply. Incorrect time applied somewhere enroute. Friend who attends standards meetings for codecs says 2kbps by tokenizing speech components. With 16QAM that's what 500Hz? Competitive wit
Curious. How did you distinguish ground wave from other modes at 100 miles over salt water. 73, -Bob ah7i Paul, Ground Wave not there above 3 MHz? It is there, in fact an antenna we developed here at

Stuart Yes, but there is also tropospheric ducting, atmospheric refraction, and scattering. Ducting and atmospheric refraction are pretty common, specially over the ocean. Was wondering, in your expe
Many tubes are cooled with finned heatsinks, which also double as shields. I'm sure many of you have seen this done. For that matter, many tubes have metal cases. Any idea if a 572B or similar tube
Wasnt the SB-230 the allegedly mobile linear, or am I thinking of a different one? Also, I seem to recall it from the era of the late 60's and/or '70's, not the '80's. 73, ron wn3vaw you are thinkin
It was the 70's and the mobile amp was (as I recall) the HA-14 using 2x 572B's. The problem with the SB230, apart from the tube being highly poisenous, is simply the cost of a new tube and the extre
Both amps work great. I wish the idea behind the SB230 could have been pursued. I don't think it is impossible to have silent operating There is no reason one could not take a pair of the surplus GI
