2304 Transverter



8 July 2023 - Have the 2304 transverter and amp in a plastic ammo box now like my 1296 transverter and amp.






The recording below is from the Cherohala Skyway during the June VHF and up contest - first time hearing the beacon.





4 March 2023 - Went to Brasstown Bald (parking lot) today to listen for the 2304 beacon on Joanna Bald but could not hear it there.  Checked my 2304 transverter, and  I found the problem - I was using 144MHz as the IF, and should have been using 434MHz.






23 January 2023 - picked up the 2304 antenna - it's a 8' Directive Systems looper.



17 January 2023 - Received the directional coupler a few days ago and measured the power at 7W out of the DEMI PA.


6 January 2023 - Tested the 2304 transverter on the bench - adjusted power out to 1W to drive the DEMI 1315 15W PA - I still need to measure the PA output - I need to locate a suitable directional coupler to do that.



3 January 2023 - 2304 transverter arrived last week and I have tested it on the bench - I am purchasing a large Directive Systems looper antenna from a ham in S.C. for use with it.  I also changed the DEMI 1315PA to a PTT-Low to key.


21 December 2022 - 2304 transverter is in customs.


15 December 2022 -2304 transverter shipped yesterday.



14 December 2022 - Per SG Labs my 2304 transverter should be shipping today - on my SG Labs 902 transverter it took about a month to receive it of which included customs processing of two weeks.


5 December 2022 - Today marks three weeks since I ordered the 2304 transverter from SG Labs - hopefully it will ship soon.


 27 November 2022 - 2304/5760 panel antenna.



14 November 2022 - Recently I picked up a deal on a DEMI 2304 15-watt PA and so I ordered a SG Labs 2304 transverter.

Collins

 32V-1 Transmitter


4 July 2023 - Finally got around to getting the 32V-1 out of the cabinet - first task was to replace the LV & HV lamps - next will be to check the two 4uF capacitors in the LV section.

I have the replacement dial from Howard Mills and I also have velum paper and the lamps for the dial segments.



18 October 2022 - Looking at a few items before firing this up - the 4uF capacitors in the LV section look leaky and they are deformed - ordered replacement capacitors for them and the two in the HV section.  I may re-stuff them or may just bypass them under the chassis, installing the new capacitors there.



17 October 2022 - Picked up the Collins 32V-1 receiver on 10/15 - this radio is extremely heavy - looking forward to testing it and getting it operational.  I already have the replacement dial rule.



22 September 2022 - Adding a 32V-1 transmitter to my Collins collection - just won the auction at $199.99 - a steal.






75A-3 Receiver


20 November 2021 - So far I replaced the limiter pot - it was frozen.  Added another filter in the "B" position.

I ordered and received a complete tube set, capacitor replacement kit, and a SSB adapter.  These will be installed at a later date.

Tested on multiple bands and works great - even SSB without the adapter works
