Ron, I can't help you with transverters, but I do have a Flex-1500 and have never had a problem running from TBolts or a DEMI 10-4. Here are my 10 MHz amplitude readings, measured by a HP 53131A Counter set to 50 ohm input. These amplitudes are zero-to-peak Volts.
TBolt-A 1.09 TBolt-B 1.19 TBolt-C 1.39 DEMI 10-4 (with 50 ohm loads on all output ports) Port A 1.30 Port B 1.32 Port C 1.32 Port D 1.32 These amplitudes range from +11 dBm to + 13 dBm John Stuart, KM6QX -----Original Message----- From: FlexRadio [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Ronald G. Parsons Sent: Sunday, November 04, 2012 11:11 AM To: FlexRadio Reflector Subject: [Flexradio] 10 MHz input to FLEX-1500 I hooked up a 10 MHz source to my FLEX-1500 and my two DEMI transverters (L144-28HP and L432-28HP). I heard satellite stations on both FO-29 and VO-52. But when I tried transmitting, I got no drive from the FLEX. After a lot of fiddling around. I noticed that if I used an 18" BNC jumper connected with a barrel to a 36" BNC jumper, the FLEX produced output, but with either jumper alone, I got nothing. Why? I have the 10 MHz source (Trimble Thunderbolt) connected to a DEMI 10-4 amplifier/filter/4-way splitter. Without the DEMI splitter, I get drive from the FLEX. But with the splitter, I needed the two cables in series. Do you suppose I am getting too much 10 MHz signal from the splitter for the FLEX-1500? And the extra cable length gave me some attenuation? Is the drive level of the 10 MHz signal to the FLEX-1500 critical?
